......................................................................................... 90 INTRODUCTION Water in the garden. It brings us refreshing coolness on the hottest summer day. It satisfies our senses with sounds that only water can make. It delights our eyes with the unsurpassed beauty of colorful water lilies, the glimmering iridescence of fish and reflections from the sky. Water has immense attraction to all people. For centuries Europeans have enjoyed the beauty of fountains and water gardens in their public squares and private estates. Water gardens create "natural" focal points, whether located in the home garden, shopping mall, or office building. This book is written to fill a void in today's selection of gardening books. A few books are sprinkled here and there, covering specific areas of water gardening such as plants and Koi, but this book is written to cover all facets of decorative water gardening for homeowners as well as professional landscapers and architects. The word "pond" conjures up different images for different people. Some envision a farm pond with a dirt bottom, fed by a creek bed and alive with ducks and frogs. Others see a mossy-covered goldfish pool in the corner of a yard. For our purposes, the word "pond" will be used in the Webster's Dictionary sense: "artificially enclosed body of water; a body of standing water smaller than a lake, often artificially formed." In this book you'll also find some of the newer terms aquasphere, aquatic habitat, aquatic environment, or waterscape. The reasons for considering a water garden are varied. Commercial landscape architects use water in their designs for effect and uniqueness. Homeowners want to exchange their rakes, lawn mowers and weedeaters for a work free garden. Others desire a pond "just like grandpa always had," yet most of us are simply looking for a garden to enjoy, a haven for relaxation. Water does have a relaxing affect, whether it be the rhythmic waves of the ocean, a gently running brook, or the quiet beauty of a pond. While we may be unable to recreate nature with oceans and brooks, we can find pleasure in designing and building ponds. MOTIVES Before deciding on a water garden, consider your motives. Ask yourself the following questions: • • • • Why do I want a pond? Am I trying to save work for myself? Do I want a part of nature in my own backyard? Am I looking for a fishpond? Or a plant pond? A fountain or waterfall? • • Do I want to cool off in the pond? Do I want to convert a swimming pool? Am I looking for a focal point in the yard or simply a subtle blend of plants and fish? Many people think water gardening means digging a hole, filling it in with water, plants and fish, and that's all there is to it. While it's true that established ponds require minimal work, prospective water gardeners should realize that a certain amount of responsibility goes with a pond garden. When you build a pond, you're putting in a natural habitat, something that is "alive" and "breathing" with plants and animals. Plants live and grow in this natural habitat; natural gas exchanges are going on; birds, bugs, fish, frogs and animals come to visit and drink from you pond. In other words, you're doing more than just cementing an area in the yard and filling it with water. You are bringing nature into your surroundings. EXPECTATIONS Prospective water gardeners should also examine their expectations. What do you want from your pond? Before starting construction, you should decide if you want a fishpond, a fish and plant pond, a fountain, or a waterfall. For example, a Koi pond without plants will be constructed differently than ponds containing both fish and plants. Do you want you pond to be a focal point - something that stands out dramatically with waterfalls or spraying fountains? Or is your life hectic and frenzied, so you're looking for a quiet haven for meditation and relaxation? If you expect a low maintenance, relaxing environment, you'll find it in water gardening. You may wonder how water gardening can be effortless. The answer is nature. Properly planned water gardens achieve an ecological balance of water, plants, fish, and snails. Water ponds answer a multitude of expectations, but the final decision on what you want from your water garden must come from you. SITE SELECTION Once you've examined your motives and expectations, your next step is to consider location. Selecting a pond site involves more than deciding where it will look best. Several factors should be taken into consideration: sunlight, drainage, eaves, trees, plants, block walls, wind, and accessibility. GENERAL SITE SELECTION REQUIREMENTS When deciding on the best location for your water garden, consider these factors: • • • • • • • Plant selection and sunlight Soil and drainage Water and electricity accessibility Appropriate viewing Surrounding landscape Block walls or barriers Wind PLANT SELECTION AND SUNLIGHT Generally speaking, a garden pond with plants and fish requires six hours of sunlight. Measure off your prospective pond site with string, rope of chalk and note the amount of sun this area receives throughout the day. The more sun your water plants receive, the better and healthier they'll bloom. Other alternatives are available for your shady areas. For example, you might consider a waterfall without fish and plants. If you want any flowering aquatic plants such as water lilies in your pond, these dictate the site be in full sun for optimum flowering. Some exceptions are such water lily cultivars as “Comanche” and “Graziella”, which flower with as little as three hours of direct sunlight. For the best growth and establishment of all of your water garden plants, a minimum of five to six hours of direct sunlight each day is recommended. If none of these conditions can be met, then consider a quiet, cool bog garden. Far from a dark, dank, mosquito infested swamp; a properly designed and maintained bog garden can be a cool green retreat in a shady summer garden. SOIL AND DRAINAGE Good drainage is one of the keys to success in maintaining a water garden. A low spot in the yard that naturally fills with water is not necessarily the best location for your pond. These drainage areas also bring insecticides, herbicides or roof chemicals, all of which may be harmful to plants and fish. However, by cultivating the soil and using drainpipes and plants, low areas may still be used as pond sites. For the best results and ease of construction, a site with a well-drained surface and subsoil is best. A sandy loam textured soil will prevent soil saturation from floating the pond liner. If the area has good surface drainage there will be fewer problems with runoff of chemical pesticides and fertilizers into the pond from the surrounding land. The more level the site the less work in constructing the pond. WATER AND ELECTRICITY ACCESSABILITY Ponds should be free and accessible from all sides. Water may need changing, or plants pruned, so accessibility is an important factor. If the pond is to contain tropical water lilies or other nonhardy plants, it is helpful to locate it close to the selected storage facility or close to a level hard path leading there. The site should have access to water sources for filling and "topping off" the pond and close electrical outlets if there is to be any lighting or filtration systems included in the design. APPROPRIATE VIEWING When deciding where to place the pond, consider the place from which you will most often view it. If this is a deck or patio, be sure that this view is not obstructed by hedges or other tall landscape features. Remember that the pond is in the ground and even tall grass or ground covers can completely obscure the view. SURROUNDING LANDSCAPE Consider how the pond will fit into your existing landscape. Ponds should be located away from the eaves of the house, overhanging trees, and dirty plants such as bamboo or pyracantha. Toxic chemicals dripping from your roof or trees are harmful to plants and fish, and dirty plants generate a dirty pond. Are there any tree roots nearby from shallow rooted plants such as elms (Ulmus spp.) and willows (Salix spp.), or trees that do not tolerate root disturbances like post oaks (Quercus stellata)? Will there be any trees close enough that leaves, fruit or twigs will present a maintenance problem? Are any of the trees walnuts (Juglans spp.)? These trees have a chemical in their roots that inhibits the growth of neighboring plants. Will the reflection of existing plant materials in the pond add to or diminish its overall appearance? Will the surrounding plants eventually grow large enough to shade the pond? Will construction of the pond necessitate construction of a fence? Will the pond cause problems in the overall pattern of surface and/or subsurface drainage? BLOCK WALLS OR BARRIERS Healthy ponds require good air circulation, so they should not be built against block walls, wall barriers or houses. Without good circulation, the air becomes stymied, causing the water to get too hot and creating improper gas exchanges. Also, if the pond is sited too close for its size to a wall or other obstructions, this could cause a problem reaching the pond’s entire surface for cleaning and removal of dead leaves. WIND While circulating air is a necessity, high wind locations will bring dirt, leaves, paper, and other debris into your pond. Wind problems can be solved with design, skimmers, pumps, and plants, but the condition should be noted before constructing your pond. STYLES AND SHAPES Water gardens can take on whatever shapes you want and what your site will allow. In terms of style, they break down into two basic categories—formal and informal. FORMAL STYLES Clean, simple, straight lines and symmetrical mirrorimage arrangements characterize formal styles. Formal water gardens have straight edges and geometric shapes. Brickwork makes a functional yet highly decorative border for a formal pond, as do square precast pavers, tile, and even sod. Formal designs work well with manicured beds of roses and neat, evenly planted perennial borders accented with clipped boxwood hedges. If your landscape design is formal and you’re considering a reflecting pool—a water feature with the principal function of reflecting trees, the sky, or plantings at the edge of the flower border—square or rectangular shapes are just what you’re looking for. For lushness, add a large display of water lilies with a towering papyrus. INFORMAL STYLES Curving, fluid lines and asymmetrical arrangements define informal design. The American cottage garden or the mixed perennial border dotted here and there with bright colors provides the perfect setting for an informal pond. An informal water garden flows seamlessly, without defined edges, into the surrounding landscape. In contrast to formal designs in which plants are used as ornaments, informal styles feature plants as the heart of the design. Foliage of similar texture and form in both the pond and perennial borders casually links the pond with the rest of the landscape. Water garden edging complements—rather than defines—informal style. Use large, irregular fieldstone, river rock, boulders, logs, or pebbles to help make a pond look as if it has always been part of the landscape. POND SHAPES Rectangles and squares are typical formal shapes. Because of their simple lines, they work well when you need to define a space, whether it’s the entire garden or part of it. Oval and circular ponds are difficult to categorize. They may be either formal or informal, depending on their size and edging and the geometry of their plantings. They more a rectangle approaches—but does not become—a circle, the more it will tend to look informal. Soft-planted edges accentuate the effect. A long narrow oval pond looks formal because as its length becomes more than three times its width, it begins to take on the character of a rectangle. It is best to complement it with the hard formal edges of cut stone or other formal materials. Free forms, such as crescents and kidney and pie shapes, are informal because of their asymmetrical edges. The final shape of your pond is determined by the relationship of its size to its edging. The proportions of plants and edging predominate in a small pond, so these elements influence shape more than the original shape of the hole. You can actually make the right-angled formality of a small rectangular pond disappear by using informal plantings. Larger ponds are harder to blend in. as the size of the excavation increases—to a quarter acre or more, for example— the shape becomes predominant. WATER GARDEN FEATURES Beginner water gardeners are often overwhelmed with the choices in detail and water features that are made available to them through the multitude of supplies. One method that many beginner water gardeners should use when designing a water garden is to always start small. Starting small with a water feature will give you the ability to change and add to your water garden as your tastes and possibly even your needs change. Starting with smaller water features in your water garden also allows you to stay within a manageable budget for the first few years until you can decide what permanent features you would like to incorporate into your water garden. WHAT IS A WATER FEATURE? A water feature is simply a small water fountain, an addition or detail to your water garden that adds some type of movement to the water. No matter how large your water garden really is you can add small features to different 'sides' of your water garden or you can add to the features of your garden to where all the smaller details form to make larger looking designs. The larger looking designs could be a series of smaller water fountains that fall onto each other and then into the water garden. The great thing about using smaller water fountains and water features in your water garden is that you can also pick these items up and take them in the house easily over the winter months if needed. Small type water fountains and water features are also easy to clean and maintain each season plus they are more affordable. On of the other nice things about using smaller water features in your water garden is that you will find them very easy to find through many home retailers so you can choose and see up close what it is you want to purchase as well as how these items look in action. You can create a dazzling display with a small detailed water fountain added to a dreary corner of the water garden where you are having a problem getting a plant to grow in order to take full advantage of the possibilities of your garden. If you would like to use a small water feature or water fountain in your garden and then you choose to move to a larger type permanent fixture you will find that many of the smaller type water fountains can be used in your gardens around your home or possibly on a large stand in your home with out much difficulty at all. ADDING ORNAMENTS Every garden, even the simplest, needs a few accessories to complete the design. After the plants are in place, relax by your water feature and imagine what ornaments might best accent the style of your garden. Sometimes basic uncomplicated forms are best when it comes to choosing decorative elements for a water garden. Sculptures that imitate wildlife, such as frogs, turtles, or water birds, suit an informal or natural setting. Plaques made of painted metal, tile or wood can highlight specific plants or feature a favorite wild creature. Not all ornaments must be purchased new. Recycled materials can become treasures in a waterscape. Flat pavers can be reused as stepping-stones in shallow pools. Old pottery bowls and dishes can hold trailing marginals and add bright spots of color to a pond’s edge. Leftover chicken wire and cable sheathing can be turned into a one-of-a-kind art object, such as a heron to stand guard in the pond. If your water garden is large, a simple footbridge across some portion of it serves as a link while providing new vantage points to appreciate the view below. If most of your pondside hours are after work, consider adding nighttime lighting to your design, in the water as well as on the landscape. Illuminating a water feature adds safety as well as sparkling beauty to the scene. Water gardens lend themselves well to fantasy, too. Fairies and garden sprites are never out of style and blend gracefully with the ephemeral feel of the water. Depending on the pose, place one on a rocky ledge above a stream or waterfall, prop it up on submerged bricks among some water lilies, or tuck it among plants near the edge of the pond for a surprise that will make guests smile. If you have children at home, lighten your idea of what is appropriate decoration, and invite them to be in on the decisionmaking. Unexpected or amusing decorations can help to reflect enjoyment in your hobby. Whatever the size and style of your design, be sure to include a chair or bench nearby from which to admire your handiwork. CONTAINER GARDENS Although many people are putting in full-scale pond features, you don't need to do that to enjoy water garden plants. Container water gardens, also referred to as tub gardens, are as much alternatives as container flowers are to a fullsize flowerbed. The only difference is that you use pond plants in a water growing media as opposed to land plants in potting soil. A tub garden is easy to build and is a great addition for a deck or sun porch. Just about any container that holds water can be made into a tub garden. A small container of only a gallon or two may be suitable for one plant. If you use a 20gallon or larger container you can even add a few goldfish. Allow about ten gallons of water per goldfish. Even a bowl can hold a small water plant. A nice size container is 12-to-24 inches wide by 12-to-16 inches deep. While you can seal ceramic containers or use liners in wooden barrels, plastic containers may be easiest to use. Just as with container flowers, group various-sized water garden containers to make a big splash. Depending on the size of the container, select a spiky, erect plant, such as sweet flag, Acorus calamus, or yellow flag iris, Iris pseudacorus. Combine with a broad-leaf plant, such as Giant arrowhead, Sagittaria latifolia, or calla lily, Zantedeschia aethiopica. Add a cascading plant, such as water mint, Mentha aquatica, or parrot feather, Myriophyllumaquaticum. You will pot your plants in containers filled with heavy, packed clay and submerge them underwater. Use bricks or an old, terracotta pot to prop them off the bottom so the foliage is above the waterline. Finish off the planting with some floating plants, such as water lettuce, Pistia stratiotes, or water hyacinth, Eichhornia crassipes. Don't crowd too many plants into a container. Two to three potted plants and some floaters will make quite an impact. Locate the container where it will receive 6 hours of sun and top it off every few days as water evaporates. When plants begin to grow, add a fertilizer tablet available at the garden center where you purchased your plants. If algae develop, remove the water plants, empty the container, refill with clean water and replace the plants. Mosquitoes have not been a problem in container water gardens as the living plants keep the water from becoming stagnant. If they do develop, remove them by overfilling your container and letting the mosquito larvae run out with the water flowing over the top. Container water gardens are really quite simple and worth a try. Begin by selecting a container that you like. A container only a few inches deep will work for some plants. If you want fish or water lilies in your tub garden, look for a container at least twelve inches deep. Be sure to place the container where you will see it often. Water is heavy and you most likely will not be moving the tub garden around once the water is added. Select an area with at least four or five hours of direct sun if you want to grow a water lily or other flowering plant. However, some protection from the late afternoon sun will be desirable for your container garden. You can grow floating aquatic plants in a shallow container of water. In a deeper container pot your plants just as if you were placing them in a full sized pond. Shallow water plants can be elevated on bricks or other suitable support. Water lilies and other deepwater aquatics should be in a pot on the bottom of the container. When selecting plants for your tub garden consider the size. There are small and large water lilies. The water lilies on our web site are rated by the size of the leaf spread. A small spread should be chosen for most tub gardens. Be sure to add two or three bunches of Anachris for every ten or fifteen gallons of water to keep the water clear. LINERS There are two basic types of liners for water gardens: flexible liners and preformed liners. FLEXIBLE LINERS Possibly the most important innovation in water garden technology is the flexible liner. Designed to replace concrete and other building materials, it allows you to create pools, streams and waterfalls in just about any shape, length and style you can imagine. The flexible liner will help you build water gardens in places not possible before. They are made from a variety of materials— polyethylene, polyvinyl chloride (PVC), and ethylene propylene diene monomer (EPDM)—and they vary greatly in thickness, cost and quality. Heavier liners will generally be more expensive, more durable and more punctureand tear-resistant than lighter weight liners. A word of warning: Do not let your dogs swim in water where flexible pond liners are used, as their claws easily damage them. If you do have dogs, go for preformed garden ponds. PREFORMED LINERS Today's preformed pond liners are quick and easy to install. Long life and low cost preformed pond liners are best for smaller garden ponds. Garden pond liners in rubber or plastic materials are best for medium sized garden ponds. For ponds less than 120 gallons, preformed liners are recommended. For larger ponds (over 120 gallons), flexible liners should be installed—performed liner ponds become rather expensive. DETERMINING LINER SIZE Measure the length, width, and depth of your pond. If you have an irregular shape, say like a "figure 8" shape, you must include the widest part of the "8" as your width and the longest length for your measurements. The depth measurement should be the deepest part of your pond. Next, put your measurements into the following formula to calculate the pond liner size you need: Length + twice the depth + 2 extra feet = length of pond liner needed Width + twice the depth + 2 extra feet = width of pond liner needed For example, if your pond measurements are 25' x 30' and the pond depth is 4', here is how the formula works: 30' + 8' (twice the depth) + 2 feet = 40’ long 25' + 8' (twice the depth) + 2 feet = 35’ wide Therefore, you would need a pond liner that is at least 40' x 35'. CONCRETE If properly constructed, concrete water gardens can last for decades. However, concrete construction is much more difficult and costly than the liner alternatives discussed before. Building a concrete water garden may require hiring professionals who have the necessary expertise and tools. Ideally, concrete should be embedded with heavy-duty steel wire mesh or reinforcing rods (rebar) for stability and durability. If improperly installed, a concrete water garden will crack, leak, and cause infinite frustration. Avoid using concrete to line a stream. Not only is it expensive, but it also looks unnatural. What you can do though is combine the beauty and durability of concrete with a flexible or preformed liner. The liner eliminates the need to neutralize the concrete before adding plants or fish, and if the concrete cracks, it won’t leak. PUMPS DETERMINING DESIRED FLOW There are several things to consider in order making a good decision for a pump purchase. The first thing is to determine your required flow rate. You will want your minimum flow rate to be at least half of your pond volume. For example if you have a pond that contains 2,000 gallons of water then you will want to pump at least 1,000 gallons per hour (gph). This is a starting point. You may find that 1,000 gph is not enough if you plan to have a waterfall that is more than 10 inches wide. Generally for a waterfall you will want 100 - 150 gph per inch of width of the weir (the portion that the water spills over). This amount will vary depending on how smooth or rough the weir is. If you want less than a full flow then less flow is acceptable. You will also need to consider your filter and ultraviolet sterilizer (UV) to make sure that you are moving the right amount of water for these devices. If your filter or UV has a maximum flow that is less than your required flow rate for good circulation of your pond water, then you will need to divert some of the water around these devices and back into the pond. This is accomplished by adding a tee fitting in the pipe coming from the pump and before your filter and/or UV. A ball valve is added between the tee and the filter. Another ball valve is installed on the other leg of the tee. Add more pipes to this leg of the tee and extend the pipe to the waterfall or to the pond. Adjust the ball valves to get the appropriate amount of water flowing to your filter. CALCULATING HEAD PRESSURE The next thing that you want to consider is the amount of head that your system will have so that the correct pump size can be determined. The three main sources of head are: • • • STATIC HEAD- this is the vertical distance you raise the water above the pond surface; FRICTION HEAD- this is the resistance from pipe and fittings as the water flows through; PRESSURE HEAD- the additional pressure required by some filters, venturis, and other devices. Most pond applications can ignore PRESSURE HEAD. First, determine the vertical distance in feet above the water surface, this is the STATIC HEAD. Next, use the Friction Loss Chart below to determine your FRICTION HEAD. Add this to your PRESSURE HEAD and you can use this figure to size the pump. FRICTION LOSS CHART Total the number of fittings and use the chart below to determine the friction loss in the fittings. Add this amount to the pipe total. This section does not apply if you are using flexible PVC. It is recommended that you use flexible PVC pipe that eliminates elbows and provides higher flow rates by reducing friction loss. Even though cost may be higher than rigid PVC pipe, it is much easier to install. There is no problem in using pipe larger than required but smaller will cut your flow rate. SUBMERSIBLE vs. EXTERNAL Before you choose your pump however, there are other things to consider. Should you use a submersible or an external pump? Submersible pumps may be a better choice for flow rates around 1,000 gph or less. Submersible pumps are usually less expensive and easier to install. However, they cost more to operate and usually don't last as long as external pumps. There are a lot of variables in determining the longevity of a submersible pump. How dirty the water, how often the pump is cleaned, and if it is operated continuous or intermittently will all influence the lifespan of a pump. The Calvert stainless and bronze pumps should last four to six years, the plastic PU pumps should last two or three years. These figures are provided as a guide only. Your pump could last less or longer than this. For flow rates between 1,000 and 3,000 gph you may want to consider an external pump but you can still decide to go with a submersible. For flow rates 3,000 gph and higher an external pump is usually the best choice. The operating cost can be the deciding factor for these larger flow rates. OPERATION EXPENSE You can determine the operating cost of any pump by using this formula: amps x volts divided by 1000 x KWH cost x 24 hours a day x 30.4 days-permonth = cost per month. If the pump is rated in watts instead of amps use this formula: watts divided by 1000 x kWh x 24 hours a day x 30.4 days-per-month. KWH is the kilowatt-hour cost, which you can get from an electric bill or by calling your local electric company. FILTERS All ponds should have biological filtration to provide good water quality for healthy fish and good appearance. Generally better pond filters mean higher cost, less maintenance, and better water quality. Ultraviolet Sterilizers are recommended for most ponds to insure the clearest water. We have selected pond filters and pond filter combinations based on pond size to simplify the selection for you. These are guidelines based on average ponds. Ponds with heavy fish loads or ponds with few plants will require larger pond filters. You cannot have too large a filter for your pond. If in doubt purchase a larger size pond filter. Shown below are suggested pond filtration systems for several pond sizes. There are two or three suggestions for each pond size. These options range, as the labels indicate, from the suggested minimum to the best systems for each pond size. The pond filters systems listed in the economy and standard columns are gravity type filters (except for the 150 and 600 gallon ponds) and need at least part of the filter system to be behind a waterfall or at least higher than the pond. If you need a pond filter system to be installed lower than the pond or one that can be positioned several feet away from the pond then the Ultima II filters by Aqua Ultraviolet will be your best choice. These pond filters are pressurized and can be cleaned with the turn of a valve. Choose one of the premium systems for this type application. SKIMMERS A skimmer prevents problems associated with leaves and other debris that fall into your water feature and present a hazard to your fish. As leaves decay and sink, they consume oxygen and produce toxic gases that escape harmlessly into the atmosphere. This isn’t a problem until winter comes, when ice forms on the pond, trapping the gases and killing the fish. A skimmer removes floating matter before it decays and sinks. It helps maintain water quality by increasing the oxygen level as the skimmed water splashes back into the pond. HOW THEY WORK The skimmer functions as a mechanical filter that sits at the edge of a water feature. A lid on the skimmer top allows access for weekly cleaning. The top of the skimmer typically sits about 1-½ inches above the surface of the pond; if the water level in your feature drops too low the skimmer runs but does not filter, sucking in air instead of water. Netting within the skimmer traps debris. A pump inside the device works constantly to draw the water into it. Water from the skimmer is then pumped to a filter, waterfall or other location and re-circulates back into the pond. PLUMBING Bottom drains and bulkhead connectors are specialized pipe fittings that allow a watertight passageway for water or power lines to go through a pond liner below the water surface. A bottom drain allows you to let the water flow out the bottom of your water feature by disconnecting the pump and turning a valve. A bulkhead connection is a specialized fitting on the side of a water feature into which you screw a pipe or pipe fitting. Guard against leaks by following manufacturer’s directions carefully when installing a bottom drain or a bulkhead connection. BOTTOM DRAINS Ponds that are stocked heavily with fish, especially koi, often include one or more bottom drains. A bottom drain made for koi ponds works just as successfully in water gardens, particularly if stocked heavily with fish. Koi keepers regularly replace 10 percent or more of their pond water. Drains make this easier to do. Installing a 4-inch-diameter drainpipe greatly reduces the likelihood of clogging. Bottom drains include a removable cover that minimizes suction created as the water drains. While skimmers work quite well at keeping the surface clear of debris, not all debris will make it to the skimmer. That which does not will eventually sink to the bottom and begin its decay process. The accumulation of decaying material on the bottom and a stagnant water system here will promote algae growth and will not be a suitable environment for fish. To overcome this problem a bottom drain will move the stagnant bottom water through the filtration system, cleansing all parts of the pond, or ensure the water the pump is drawing from comes from the bottom of the pond. If the pond is greater than 18 inches deep, it should have a bottom drain. BULKHEAD FITTINGS A bulkhead fitting is a special plastic fitting to provide a watertight seal through a plastic container or a flexible pond liner. This fitting allows full flow of water and the ability to attach flexible pipe with the use of a male adapter. The fittings have left handed threads to keep the fitting tight when installing the male adapter. COUPLINGS Couplings are used to attach one piece of pipe to another. These may be the same or different sizes. Rubber couplings are also used when installing a pump, UV or other device that you may need to quickly disconnect. BUSHINGS A Bushing is a part that is glued* or threaded (Female Pipe Threads) into a fitting such as a coupling or elbow to adapt to a different pipe size. * When working with PVC and ABS pipe always use the all purpose glue. HOSECLAMPS Hose Clamps are used to keep tubing attached firmly to the barbed side of a male insert. SCREENS Signal Pond Products Intake Screen—This screen with 3" elbow is made of ABS plastic and attaches to 3" PVC or ABS plastic pipe. It will prevent leaves and other large debris from entering filter. Signal Pond Products Intake Screen 2” Straight—This screen is made of ABS plastic and attaches to 2" PVC or ABS plastic pipe. It will prevent leaves and other large debris from entering filter or pump. Signal Pond Products Intake Screen 3” Straight--This screen with is made of ABS plastic and attaches to 3" PVC or ABS plastic pipe. It will prevent leaves and other large debris from entering filter or pump. MALE ADAPTER MALE INSERT A Male Insert is used to connect flexible tubing to a pipe or a device. One end is threaded and the other is barbed to hold the tubing. FLEXIBLE PVC PIPE Flexible PVC Pipe is a very strong pipe that is, as its name implies, flexible which makes it easy to work with. It is designed to fit into standard schedule 40 PVC or ABS fittings where it can be glues into place. Flexible PVC provides more water flow than rigid pipe using elbows to make bends would allow. BALL VALVES Ball Valves are used to regulate water flow through a pipe. They allow for complete flow when fully open. CHECK VALVES Free Flow Check Valves are used to provide flow through a pipe in one direction only. When installed between an external filter and the pond, it keeps the dirty water in the filter from flowing back into the pond if power is lost. They are also used to keep an external pump primed if power is lost. Spring type check valves should never be used in a pond installation. GATE VALVES Gate Valves, referred to as knife valves by some, are easier to use than a ball valve for fully opened or closed operation. They are not used for regulating flow. EDGING Edging your pond will give it a finished look. You can hang a picture on a wall by itself but put a frame around it and you have a masterpiece. This goes for your pond. Put an edge around it and it stands out and calls to you to notice it. Edging will also secure your pond liner beneath it. There are many types of edging. Raised edging or tilting the edging slightly upward will help to discourage surface runoff from entering the pond. Your edging can be extended over the edge of the water by 1-2 inches to conceal the liner from the sun and your view, making it more attractive. Mortaring the stone or brick edging will provide a safe and secure edge. Brick or cut stones gives a formal look to your pond. A mixture of edging can create an informal look to your pond. Plants can be used to cascade over the edges to give a soft natural look. If you use plants, leave an area where you can walk close to the water. The use of plants can be inexpensive and easy to install. Place your plants far enough back from your pond's water edge so that when they cascade over the edge they won't cover too much of the water surface. Keep them trimmed back. You can grow grass up to your pond's edge but keep it and all the clippings out of your water. Dwarf and low-growing conifers, evergreen ground covers and spreading broadleaved evergreens make for a satisfactory edging for your pond. You can use tall ornamental grasses growing behind the pond with smaller grasses toward the sides. This allows you to see your complete pond from the house. The taller plants are used for a backdrop and are reflected in the water on sunny days. You will get ideas from visiting other ponds and you can see many ponds in one day by going on a pond tour. LIGHTING You can create amazing effects with water feature lighting—make a fountain glow, illuminate an entire pond from within, highlight an attractive statue, or heighten the reflection of a beautiful tree. Water garden lights are available for installation as either in-water or out-of-water lighting. All, however, should be connected to a GFCI outlet for safety, and those used in the water should be made specifically for underwater use. There are several types of in-water lights, and each creates its own special effect, depending on how you position it. Most designs call for lights that have dark, subdued casings. Stainless steel or white casings can be obtrusive, especially during daytime. Fountain lights, either in white or colors, add drama to a spray. Some fountain lights also come equipped with transparent wheels of several colors. Use colored light sparingly, however. Too much can look gaudy. TYPES OF LIGHTS • Floating Lights—Drifting on top of the water, floating lights create a festive atmosphere. Some have smoked glass, which has a more subdued effect. To hold the lights in once place, anchor the cord with smooth-edged brick or stone. • Submerged Lights—Made for underwater use, submerged lights illuminate the pool or draw attention to features outside the pool, such as special plants or statues. They also add drama when installed under fountains or waterfalls. Underwater lighting is available for both floodlighting and spotlighting effects and their lighting is diffused. • Floodlights—Use the wide beam of a floodlight to illuminate large areas. Inside a pond or pool, it can make the body of water seem to glow from within. Outside the pool, it’s best to restrict lighting to a seating area, such as a deck, because it produces a glare if directed at a sharp angle to the water. If used outside the pool, position it to shoot across the water at a low angle. • Spotlights—whether under or out of the water, the tight beam of a spotlight can shine upward to highlight a specific feature. Place it beneath an attractive element, such as a waterfall, and the element will appear to glow. When carefully positioned under the water, a spotlight can create a reflection of the feature it illuminates. Outside the water, aim it to highlight a feature in the water or place it under statues, trees, or large poolside plants. • Out-of-water lights—Low-voltage lights that can be installed along a path or at the water’s edge include spotlights, floodlights, and decorative light fixtures located outside the water. Use them to increase safety for nighttime strolls or to highlight focal points. UV CLARIFIERS Algae in the form of "Green Water" commonly occurs in ponds. The algae itself is not a problem but it looks unsightly and hides your fish. Fortunately there are a number of things you can do to rid yourself of green water. Algae requires nutrients and sunlight to thrive - so therefore the goal of the pond keeper is deny algae these ingredients. • Shade as much of the water as possible with lilies and other aquatic plants. Algae requires sunlight - so floating plants prevent sunlight from feeding the algae. • All aquatic plants absorb nutrients from the water that would otherwise be used for algae. • Feed your plants only as directed. Fertilizer tablets can be inserted into the soil - so the fertilizer is absorbed by the plant roots with very little released into the water for algae to consume. A guaranteed way to keep water clear is the addition of a UV Clarifier. Exposure to the correct wavelengths of UV light kill the DNA in algae. Once it dies and clumps together, the external filter can filter it out. This has become a very popular and effective way dealing with green water. A clarifier kills beneficial organisms only if they get into the UV chamber, but it won’t affect the beneficial bacteria that colonize inside the biofilter and on the sides and bottom of the pond. Aquatic plants should be included in a plan that uses a UV clarifier. Otherwise, you’ll end up with clear water that’s full of nitrites, which can be detrimental to fish. HOW IT WORKS A UV clarifier consists of an ultraviolet bulb inside a quartz-glass tube and PVC housing. A pump forces water through a pipe to the UV unit, which sits outside of the pond. The water is irradiated as it passes between the inside of the housing and the outside of the glass tube. (The light breaks down algae). The water is the returned directly to the pond or via a biofilter, waterfall, stream, fountain, piped statuary, or bog. UV clarifiers are labeled according to their wattage, maximum gph, and recommended pond size range. Their strength varies. If the maximum flow rate for the UV clarifier is exceeded, algae will move past the UV light too quickly to be killed. Buy a clarifier with a maximum gph capacity that exceeds the gph of the pump that powers water to it. A higher wattage means that the unit can successfully handle a greater gph. Because clarifiers kill bacteria, remember to unplug the UV unit when adding beneficial bacteria to a biofilter or directly into the pond. Resume operating it when you want to rid the water of suspended algae. A UV light bulb is good for a single season, so replace it each spring. Even if the light continues to burn for a new season, its spectrum will no longer be effective. ELECTRICITY You can successfully operate an ecologically balanced water feature without using electrical power. But most water feature owners prefer to add the visual, aural, and biological benefits that moving, splashing, pump-powered water provides. Other pond accessories require electricity as well. Outdoor lighting enables homeowners to view their gardens in the evening and at night. Fishkeepers in cold regions rely on deicers to safeguard their prized fish during winter. Before starting any electrical installation, learn about your local electrical code from your city or county inspector (department of building inspection). Also check the National Electric Code (NEC), which gives minimum standards for outdoor wiring. Local building codes may have particular requirements, depending on climate and soil conditions. For example, your local code may require underground power lines to be encased in conduit buried at a certain depth. DIGGING THE HOLE The most unappealing part of creating a garden pond is the digging. However, with some planning—and when done properly—digging can be downright fun. When planning your garden pond, take into consideration how much digging you can do and adjust either the size of the water garden or the amount you do alone. Digging even a small pool is not a job for a person with a history of back pain or heart problems. WHAT TO DO Start by marking the site with a garden hose, rope, or garden lime. Then finetune the outline with stakes (every foot or so) and twine. Cut alone the outline with a spade; then remove the top layer of sod. If you’re going to use turf as edging, cut the sod approximately four inches in from the outline of the pond. Remove the sod inside the outline and peel back the four-inch strip. After installing the liner, flip the sod back over it. To edge with stones or other material, dig an outwardly sloping shelf (six to eight inches wide by two inches deep) for the liner and the edging. The trench should be deep enough for the edging stones to sit flush with the ground or three to four inches deep for a concrete footing for edges that will get heavy traffic. With the grass removed, mark the outlines for marginal shelves; then begin digging from the center outward. Dig two inches deeper than the pool depth to allow for an underlayment of sand (less for other materials). As you dig, angle the sides slightly, about 20 degrees, and make sure the edges of the pond are level, or the liner will show. With a small project, you can place a carpenter’s level on a straight piece of 2x4 to check al around the pond. For a larger project, put a stake in the center of the pond with its top at the planned water level. Rest one end of a long straight board on the stake and the other end on the edge of the pool. Check the level. Rotate the board a few feet, again noting the level. Repeat until you return to the starting point. Use the removed grass to patch bare spots in the yard to add it to a compost pile. If the topsoil is in reasonably good condition, add it to the vegetable garden, spread it on flower beds, or create new beds and berms. If you’re installing a rigid liner, set aside the soil to backfill around the liner. Put the soil in a wheelbarrow or on a large tarp or piece of plastic to protect the lawn. Discard clay-laden subsoil or use it to build up a slope for a waterfall. Dump larger amounts at a landfill. INSTALLING A FLEXIBLE LINER While you are digging out your pond, take into consideration that you should put 2" of light sand onto each layer to help prevent rocks, roots or debris from puncturing your liner. After you have completely dug your pond out, level each of the shelves and thoroughly go through the entire pond and remove any rocks or debris that may be protruding. Add approximately 2" of sand inside the pond to act as a "cushion" and protector under your pond liner. Lightly sprinkle the sand with water and tamper it down. It is also recommend that you use a geotextile underlayment for under your pond liner as well, which helps protect the liner from any rocks or sharp objects. By adding the sand and underlayment, it also helps to provide protection and "cushion". STEPS Pond being dug working from the middle out, including bog and marginal shelves. The mound of dirt at the opposite end will be used for a waterfall. More dirt will be added later. Once everything is leveled, dug properly, bottom drains installed (if desired) and sand and geotextile underlayment are installed, it's time to put in your pond liner. Open the liner and with the assistance of some friends or family members, carefully drape the liner across the pond making sure it overlaps and has equal distance on all sides. (Your pond liner will be larger than your pond when you drape it over.) Secure the edges with rocks or bricks and start to fill it with water. Liner draped over pond ready to be filled. Gravity allows the liner to "sink" especially in a large pond. The water pressure will cause the liner to contour around the edges within your pond. By the way, you don't have to walk into your pond and manually contour the liner to the edges; the water will do that while it is filling. Try to have any folds or wrinkles out when you start to fill it. While the pond is being filled, you can tug and move the liner a bit to work out any folds that develop. Once the liner is taut, you can reposition the rocks or bricks at the edges allowing for the liner to sink down and fill with water. Continue filling your pond with water. Be sure to straighten out any pleats or folds in the liner as it is being filled. Some pleats are inevitable, but the less, the better. Take some pictures of your pond during different stages of creating it and while the pond is being filled. You'll enjoy looking back at the photos and have a "brag book" to show your friends and family! The pond is completely filled with water. This pond took approx. 40 hours to fill over the course of 3 days (it is over 26,000 gallons). The excess liner has been trimmed around the pond and will be buried and covered up with landscaping. Once the pond is filled with water, you can trim the excess liner off. If you calculated the size of your pond liner accurately and positioned the liner correctly, you should have a little excess liner that needs to be cut off. You can cut the liner relatively easy with an Exacto knife or sharp scissors. Depending on how you decided to landscape the edge of your pond, you can dig a small trench around the pond and bury it with dirt or you can hide it with coping stones, boulders, etc. One important note to consider when creating the pond is the edge of the pond and landscaping around it. Do you want a very pronounced and defined edge with bricks or coping stones or slate? Or do you want a natural border with cobblestones, rocks or boulders? The edge of your pond helps defines it's "mood" as well as the landscaping around it, so give it some thought. You will need to decide these things while calculating the size of the pond liner, in case you need extra liner. Regardless of what material your pond's edge will be, make sure that it's edge is at least 10% higher than the ground around it. This will help prevent water from rain or sprinklers from going into your pond and any chemicals or fertilizers in the soil around it. If you have your pond in part of a natural hill, you may have to create a trench on that side of your pond, fill it with pea gravel and sand, which will help divert the water from your hill from going down into your pond. In this case, you may need a professional landscaper with experience in creating ponds to do the work for you. Once again, definitely have the edges of your pond at least 10% higher than the ground around it. You can easily do this with the dirt that came from digging out your pond. This edge must be level too, or else you will have water leaking from the lower areas. Trim the excess liner off with an Exacto knife or sharp scissors. The liner can be buried in a little trench around your pond or with coping stones and boulders depending on your landscape design around your pond. This pond has a cobblestone edge, which have smooth edges. Part of the cobblestones go into the water and a "lip" was created while the pond was being dug to hold back the cobblestones from entering the pond. One important note to make about putting cobblestones or rocks around the pond's edge. The cobblestones, no matter how much you rinse them off with a hose, will add a lot of dirt to your pond and you'll be so disappointed especially after seeing the crystal clear water in your pond from the garden hose. You will have to put your liner in, fill your pond up with water, add the cobblestones to your pond and then drain all of the water out, rinse off the rocks even more, clean your pond out and then refill the pond. This is a big step and can be very time consuming and cause your water bill to go up, but you have to do it and in the order described. The cobblestones have to be cleaned and this is the only way to do it (unless you have a small pond and want to wash each cobblestone off in a bucket of water). Naturally other rocks, coping stones, etc. should be cleaned as well. The landscaping is not complete in this photo. Three waterfalls will be created at the end of the pond. You can see one waterfall in this picture and the cobblestone edge. Bog and Marginal Plants will be planted within the pond as well as landscaping done around it. Another view of the pond "in process". The waterfall is incomplete and was being constructed. The pond is 25' wide x 35' long x 4' deep. Hoses will later be buried and hidden within the landscaping. Water hyacinths are seen floating on top of the pond. INSTALLING PREFORMED LINERS Choose the largest liner possible that suits your site and your pocketbook. Preformed units appear smaller once installed, filled with water, and edged. If you want to keep koi or goldfish, the pond should be deep enough to accommodate them; if it has plant shelves, they should be wide enough to hold the pots you will use for planting. After determining where you want to install your pond, carry the preformed unit to the site. Orient the liner, topside up, on the spot where you want to install it. Use a carpenter’s level and plumb bob or a weighted string to establish the outer edge of the pond. You can’t simply mark the outline of the form’s bottom on the ground and start digging. Preformed rigid pond walls slope slightly inward (from top to bottom), making the top perimeter larger than the bottom perimeter. The plumb bob drops straight down from the top perimeter, enabling you to outline the perimeter on the ground directly below it. Mark the perimeter using a rope or a hose. Enlarge the entire perimeter by two inches to allow working room within the excavation. The extra space will be filled later with sifted soil or sand. Finalize the outline by marking it with spray paint, flour or sand. Preformed ponds can be used as built in ponds or aboveground ponds. For a superb, natural effect, the best these days are fiberglass-preformed ponds. Building backyard ponds becomes simplicity itself. The very best preformed ponds these days are made from fiberglass and come complete with rock edgings built into the preformed ponds. Such preformed ponds cost the least overall if you want a built in pond. Not only are the total costs of preformed ponds lowest, but also the difficulty of installing edgings is removed completely. The job is also finished in a fraction of the time it would take if the edging had to be done separately. The strength of fiberglass-preformed ponds allows them to be used for both inground and aboveground garden pond installations. You can also do away with digging completely by buying aboveground preformed ponds. This makes preformed ponds ideal for patio or even indoor preformed ponds. The alternative to fiberglass-preformed ponds is flexible plastic garden pond liners. These garden pond liners need much more attention to detail to complete and require some skills not required for installing preformed ponds. STEPS 1. Select an area that is sunny and has at least 46 hours of sunlight. Good drainage is a must. Root free would be great, too. 2. Standing inside the pond, mark the pond's perimeter on the ground, using an edger or flat shovel. You can outline it with chalk dust as well. 3. Dig a corresponding hole a little larger and deeper than the pond. Make sure the excavation has a firmly compacted base. Take out any rocks, roots, or sharp debris. You can put approx. 2" of play sand base under the pond and have some for around the edges. NOTE: For our molded shelf ponds, simply replicate the pond's contour within the excavation, making sure to fully support the shelf with tightly packed sand or dirt. Rinse out pre-formed pond with water real well before installing. 4. Bed the pond on a layer of sand, then level the pond. You should have the pond's edge slightly above ground level so the dirt around it slopes at least 10% away from the pond to prevent rain from washing soil, lawn fertilizers, etc. into the pond. 5. Backfill with loose dirt or sand between pond and excavation, stopping at halfway mark between excavation base and pond's flange (upper lip). Start to fill with water. 6. Commence filling with water slowly and continue backfilling with loose sand. Gauge your time so the filling of water and backfilling of sand steps are finished at the same time. If water is chlorinated, allow 48 hours before adding plants. If you are adding fish, you need to dechlorinate the water before adding fish. If you got dirt in the pond while backfilling, it is a good idea to drain the pond completely, wipe clean (never use detergents) and refill with water. 7. (Optional) A layer of washed, lightly colored stone (pea gravel, cobblestones) may be arranged within the pond prior to stocking. Dirt and sediment will rest upon the rocks, becoming less noticeable. Decorate with rocks, bridge, aquatic plants, lighting, fountains, or whatever your imagination decides. 8. (Optional) Combine two or more ponds for a stronger, more dramatic presentation. BUILDING CONCRETE PONDS BEFORE YOU CONSIDER BUILDING A CONCRETE POND, YOU WILL HAVE TO HAVE BASIC MASONRY KNOWLEDGE, OR HIRE SOMEONE WHO DOES. OTHERWISE, GO WITH A LINER. Excavating a concrete pond is done along the same lines as for liner ponds, except that some allowances need to be made for a base about 6" thick and sloping sides 4". If the sides will be vertical allow for 6" walls like the base. The depth of the excavation should include a layer of compacted hardcore like crushed stones or bricks. STEPS 1. Cover the base of the excavation with hardcore as described above. Compact it into a layer that is 6" thick. Renting a electric tamper may be a good idea if your soil is sandy. 2. Make up a dry mixture of concrete consisting of 3 parts coarse aggregate; 2 parts sharp sand; 1 part cement. Mix thoroughly. 3. Add enough water to form a consistency that allows a slit made with a shovelhead to remain open. 4. If the pond is small combine steps 5 and 7 into a single operation. If your pond is fairly large then follow steps 5, 6 and 7 separately. 5. INFORMAL PONDS: Lay concrete along base and around the sides of the pond to a depth of about 2 ½” FORMAL PONDS Lay concrete only along the base of the pond to a depth of about 2 ½”. 6. INFORMAL PONDS: Cover base and sides with a layer of heavy gauge chicken wire to prove reinforcement. Steel mesh or rods may be used if the pond is very large. FORMAL PONDS: Use chicken wire only on the base, with rods or mesh being installed later when the pond sides are constructed. NOTE: Either way, bed the chicken wire into the concrete to ensure no exposed areas protrude after Step 7 is done. Exposed Bits of wire will rust quickly and cause problems later on. 7. INFORMAL PONDS: Lay the remaining concrete to a depth of about 5 ½ " along the base and 3" on the sloping sides and shelves. FORMAL PONDS: Finish laying the base to a depth of about 5" but only if shuttering, can be installed immediately. Otherwise, do not complete the base but key the surface instead to ensure an effective joining when the final layer of concrete is added on. (Shuttering are the wooden forms you need to hold the concrete in place for it to dry and harden.) HINTS: The shuttering or forms should leave at least a 6" gap between it and the earth wall. Slowly pour the concrete and insert chicken wire or other suitable reinforcement material. 8. FORMAL PONDS ONLY: Install shuttering/forms if the pond is small enough to allow this to be done without having to step on wet concrete. 9. FORMAL PONDS ONLY: Mix up concrete of the same grade and consistency as that used for the pond bottom base and shovel this into the cavity between the form and excavation walls. Always wet the shuttering or forms with soapy water before you start. You don't want it to stick to the forms. Once you have poured a layer a few inches thick, you can place reinforcement rods or wire down in the concrete supporting it at the top of your forms. 10: FORMAL PONDS ONLY: Allow the sides to set for 24 hours. Then remove shuttering/forms. 11. FORMAL PONDS ONLY: Finish laying pond base if it was not completed at the end of step 7. The final thickness should be around 5" total. Allow to dry 24 hours. 12. FORMAL AND INFORMAL PONDS: Prepare a dry mixture consisting of 3 parts sharp sand; 1 part cement, add waterproofing powder at this stage, if you want. If you want to add concrete dye for coloring, this is the time to do it! 13. Gently add water to the dry mixture until it is like a stiff paste. Be sure to prepare enough to cover the whole pond to a thickness of 1". This is called rendering. Apply the rendering with a trowel leaving no ridges or depressions. Get it a smooth as you can. Work quickly so it doesn't dry out. 14. You may find that a small amount of water collects in the bottom. If so, it will disappear is an hour or so. If it is hot outside, you should cover the surface with most sacking to slow down the drying process. NOTES: Opinions vary as to how long you should wait before filling with water. If your weather is damp, allow it to cure for 1 week. If the weather is hot or really dry, 3 days should be sufficient. SAFE FOR AQUATIC LIFE A newly constructed pond is far to hostile to all forms of life, so you must make it safe for the fish and plants. The main danger is from the lime in the concrete. We recommend building one in the fall allowing for the winter months to achieve a safe level of maturity. You can seal your new pond by applying 3 coats of polyurethane resin to the surface. This coating dries in about 30-45 minutes, allowing you to complete your sealing sooner than other products. BE SURE that you completely cover the surface leaving NO holes or untouched areas. If you do, the lime will leech and you will kill everything in your new pond. IMPORTANT: You must fill and drain the pond several times before filling to introduce fish and plants. This removes impurities and renders it safe. Last wash should be made with a mild detergent and a good rinsing. If you want wait a few months and fill and drain the pond 2 times a week for 2 months you can eliminate the above procedure, but don't know why you would want to. Now you have the information you need to build a really nice Formal or Informal concrete pond. One last point here. Concrete does deteriorate over time if left unattended. Cracks appear and leaks develop. Some people opt for installing an EPDM liner over the new concrete, which means your pond is ready to go as soon as you fill it. No waiting! BUILDING ABOVE GROUND PONDS Aboveground pools and ponds are good options where digging would be difficult, and they’re also appealing because they bring the water up close, which is especially enjoyable near a patio or other sitting area. Raised water features tend to take longer than sunken ponds to build and usually cost more. However, they’re less likely to become cluttered with blowing debris or eroding soil. STEPS 1. Place the pool liner in position and mark out the shape on the ground around it 2. Carefully remove any turf within the shape and excavate to a level soil surface slightly larger than the shape. A long spirit level, or a spirit level with a long straight edge is essential. The shape of the pool to satisfy your landscape design ideas must be marked on the ground plumb with the outside edge. 3. From this line inwards 2 inches (5cm) and outwards by possibly 4 inches (10cm) a small 4-inch (10cm) deep trench for a footing must be excavated and filled with a semi-dry concrete 5:1 mix of 'All-in' ballast and cement powder. The width of the footing depends ultimately on the thickness of the facing stone or brick that the water feature is intended to have. 4. If the pool is to be partially set in the ground (landscape design ideas?), the base of the pool should be marked on the ground and the resulting shape excavated to the required depth at which the base should be flattened and leveled. 5. A 4inch (10cm) concrete block wall will be built up to support the rim of the pool. A single line of concrete blocks is sufficient to support the pool out of the ground at marginal shelf level. The depth of a standard concrete block (9ins or 23cm with mortar) generally corresponds the depth of most manufacture's pools at the marginal shelf. Two high, they correspond to the complete depth to the base. Slight variations can be taken up with a layer of brickwork or thick mortar joints. Leave the vertical joints of the block work partly open to begin with, in order to facilitate the backfilling with sand. 6. With the block work in place, replace the liner on a thin 1-inch (25mm) cushion of sand. If it seems well supported fill it with water. Flimsy liners can filled to the marginal shelf level. 7. Leave it there full of water over night to do any settling that might occur, before you attempt any edging. If it shifts - empty it and build up the sand support where it has sunk. Gently ramming down the backfill further at the lowest point can make up tiny fractions in subsidence. If you need to do this don't overdo it because it can buckle up the rim of the liner, which you want to keep as flat as possible to take whatever edging you might want to choose to go round it. As you backfill the pointing to the upper parts of the blockwork must be completed 8. The facing stonework to the pool can be started at any point using the blockwork as support. You could alternatively use a wider block (6inch or 15cm) and just render the face of the blocks with cement. With the stonework built level, and edge can be laid in place. 'Profile edging' or segment paving saves cutting slabs, or in natural stone, crazy paving is most popular. MAKING A BOG Putting a bog garden by your pond or anywhere for that matter makes a great project. The best part about a bog garden, other than how great it looks, is that it is maintenance free. THINGS TO CONSIDER • • • • Bog plants perform best in a sunny or lightly shaded spot. It's best to situate it in a low-lying area. A nearby hose is preferred. You can actually make your bog deeper at one end so that you can plant true bog plants at the deep end and some merely moisture loving plants at the other. A plot of land 3' wide by 4' long or smaller is fine for the beginner, with a pit of 16" to 24" deep. STEPS 1. Mark out the shape of your bog garden with a piece of rope or your garden hose. Make it informal. Remove all the turf/sod with a shovel and discard it. 2. Excavate the top soil (usually 4"-5" down) and put it on a tarp or a piece of plastic next to the excavation. You can mix this in with your " bog soil" mixture. Now, excavate the entire pit to the ultimate depth. 1 1/2’ to 2’ and discard all this soil, as you won't be using it. 3. To make the soil in the pit more water retentive, line the pit with a double layer of black plastic. Spread it across the bottom of the pit, and up the sides working it into the corners. 4. Press all the wrinkles flat and cut the edge all the way around about an inch or two below ground level 5. Punch holes everywhere in the bottom so that the plastic will retain most of the water in the bog but the excess will drain into the underlying ground. This slow drainage will prevent the bog soil from getting to water logged and rancid. 6. Bog plants prefer a soil rich in humus so we need to make a mixture of " bog soil". A mixture of 50 % peat moss, 25% compost or cow manure and 25% heavy black dirt works the best. 7. For a bog garden 3' x 4' you will need 2-3 bales of peat moss, 4-5 bags of cow manure and three or four bags of heavy top soil. Mix this all together (add in the top soil you saved at the beginning) on a tarp or piece of plastic and fill in the pit to within an inch or so below ground level. This slightly below ground level encourages rainfall to drain into the bog. 8. Top off the soil with hardwood mulch, don't use pine...and fill the bog full of water with the hose. The mulch helps to reduce the moisture loss and also keeps the weeds down. With all the humus the soil mix will be springy and almost squishy just like a bog. In the deepest and wettest portion of the bog you can use true bog plants native to this area, including Pickerel Rush, Arrow Head, Horse Tail, Cattail and Marsh Marigold. You can also use perennials that like damp soil at the shallow end. Irises, Yellow Flag Iris, Tiger Lilies, Common Ferns, Zebra Grass, Sweet Flag, etc. MAINTENANCE Maintaining bogs is almost painless. Depending upon the amount of rain received you might need to fill the bog with water once or twice a summer. Let the water run into the bog until it overflows. BUILDING WATERFALLS Preformed waterfalls allow for simple do-ityourself installation. Most preformed units are made of fiberglass or plastic; many can look natural. Sizes range from a foot high to six feet or higher. You may choose among units that include a built-in hidden filter. Use the manufacturer’s guidelines for installation and its suggested range of gph (gallons per hour) to help you choose. Keep the falls within the recommended gph because too much flow can cause water loss and too little flow can result in a loss of visual and aural impact. Fountains and waterfalls give the water garden a focal point in addition to adding beauty. Furthermore, place the focal structure in a location to get the greatest viewing impact. Fountains come in a wide range of shapes, colors, sizes, price ranges and are available at many related retail sources. A waterfall is generally created by building a slope using excess soil, liner material and assorted rocks to create a stream that is recycled with a submergible pump. Plastic tubing or a dark colored water hose is attached to lead from the pool pump up-and-under the waterfall during construction. It is especially important that the height of the waterfall or fountain spray coincide with the size of the water garden. STEPS 1. Placement of pump Secure the flexible tubing to the outlet of the pump using a stainless steel hose clamp. Submerse it at the furthest point from the waterfall. Route the tubing over the side of the pond (it can be hidden under the perimeter stones). Make sure the tubing is not pinched by the stone, and avoid sharp bends in the tubing so it does not kink and reduce flow. 2. Tubing Route the tubing to the waterfall. Bury it under soil. 3. Building waterfall pond Use displaced soil from the pond to build an elevated area for the waterfall. Consider making a small auxiliary pond in this mound. Position the spillway to flow into the main pond area. Build the small pond using the same techniques and liner as the main pond. Two layers of liner are recommended for this pond. The first one contains the water. The second liner channels the water towards the fall. Important! Be sure the liner drapes underneath the waterfall spillway stones otherwise you will experience water loss when the waterfall is in operation. You may need to use liner seaming tape in this stage. 4. Building spillway Once the spillway liner is in place, you will want to pump water up to the auxiliary pond and watch it flow down the liner spillway. (At this stage - your pond should be full of water). Carefully select stones and position them while the water is flowing over them. With the water flowing over the rock, you may replace, shift and add stones so you achieve the desired water spills you desire. 5. Adding extras Plant moss and small plants between the stones around the waterfall to achieve a natural look. Note: The discharge from the filters can be routed to the waterfall pond or into the water stream. Because the water flows by gravity out the bottom of most of the filters, it must be positioned higher than the waterfall. If this is difficult to achieve, consider a "Y" or "T" connector in your tubing or use the pump diverter, with some water being diverted to the filter and some to the waterfall. You may also want to use two separate pumps, one for the waterfall and one for the filter. OTHER CONSIDERATIONS • Building backyard waterfalls to handle more than 1,000 gallons per hour or building waterfalls for large volume flows normally should be reserved for larger koi ponds where this kind of flow rate is very important. When building waterfalls for smaller ponds aim to use gentle flow. As well as gentle flow soothing sound should also be a main criterion or concern for building a pond waterfall. • Building waterfalls high and wide on a small pond makes no sense. The outcome will look odd and be very noisy. • Building waterfalls impacts significantly upon your choice of pump for any pond. Get the FREE Excel spreadsheet above to make sure you do not get this item wrong. A backyard waterfall with the wrong pump can be very disappointing. • For every inch of garden ponds waterfall lip width allow 250 liters per hour of pond water flow (about 50 gallons). Remember your backyard pond waterfall should send out soothing sounds, not great roars. • Building waterfalls high? For most small garden ponds (up to say 500 liters or 120 gallons) building a pond waterfall 18” or 50cm above the pond surface is good enough. For large koi ponds 1 meter or 3 feet is probably high enough. • Do not switch off the pond waterfall (be it a fiberglass waterfall or any other kind) at night if you have a koi pond or a fish pond unless you run a second pump to feed the bio-filter, which keeps the fish alive. Oxygen required by fish and biofilter bacteria is supplied from circulating water flowing down such a fiberglass waterfall. • Building waterfalls is fun and easy using synthetic rock waterfalls made from fiberglass. Certainly a preformed waterfall or preformed waterfalls stacked together is the way to go. Forget digging and concrete or liner waterfalls. They are too difficult and costly and add no extra value over any fiberglass waterfall I have ever seen. WATERFALL EXAMPLES CREATING FOUNTAINS You've seen them on TV: huge, complex water features, with high-cost water fountains, installed by skilled landscape designers. Rather daunting, aren't they? You want a water feature for your own landscaping, but just a small water fountain, you say? A cheap, low-maintenance garden water fountain whose gurgling sound will soothe those frayed nerves when you pull into the driveway after a hard day at work? Well this easy do-it-yourself project for beginners tells you how to build just such a water feature. Before excavating the hole for the pond liner of your outdoor water fountain, have a certified electrician install an outdoor outlet near where the artificial pond will be, if you don't already have one. Since the cord length of the pump I selected was 6', I determined a location for my water fountain that would be within 6' of the outlet. An ideal location in your landscaping for a water fountain is near a patio. While relaxing on the patio, you'll be treated to the soothing sounds of the water fountain. STEPS 1. Your first landscaping task is to remove any weeds from the area you've selected for your outdoor water fountain, and make sure it's level. Then you will dig out the hole, into which the preformed plastic pond liner will be placed. To get an accurate measurement for the hole's dimensions, simply flip the preformed pond liner upside down and trace around it. The pond liner that I used is just a small, cheap, rigid liner, 6" deep with a diameter of 2'. 2. A water feature using a pond liner of this size will be just large enough to make a statement in your landscaping -- if you make it the focal point of a small niche on your landscape. Just use a "big fish in a small pond" approach (pardon the pun). That is, make sure your water fountain is situated in an area of your landscape where it won't be upstaged by larger elements. When you choose plants to grow around your water fountain, make sure their height at maturity is short, relative to the water fountain statuary. Draw the eye to the artificial pond by having a stone path lead up to it, by accenting it with a bright color, or by any one of a number of similar landscape design tricks. 3. Make the depth of your hole about what the depth of the pond liner is. Try to make the diameter of the hole match that of the preformed plastic pond liner as closely as possible, for a good tight fit. If, however, you find you've made the hole too wide, use sand to fill in the gap. 4. Sand will also be used at the bottom of the hole, since a sand floor will be malleable enough to allow you to play with the height of the pond liner. Put about an inch of sand in, so that the top rim of the preformed pond liner will stand about an inch above ground level -- reducing the amount of dirt that will keep falling into your artificial pond. You'll be pushing the sand around to get the level of the pond liner just right. 5. Next, place the preformed plastic pond liner into the hole. Check for levelness by placing a carpenter's level across it (see photo left) -both front to back and left to right. Depending on the readings you get from the carpenter's level, it is at this point that you'll have to remove the pond liner from the hole and adjust its sandy floor accordingly. FOUNTAIN STATUARY It's the decorative statues that really make an outdoor water fountain a focal point of your garden. But if our goal in this artificial pond project is building a cheap fountain, we'd better employ some do-it-yourself tricks to keep costs down. It's easy enough to go out and buy a costly water fountain statue with the "plumbing" all ready to go. But with a little ingenuity, we can reduce the cost of this artificial garden pond project considerably. We'll simply be making plumbing where no plumbing existed before! This also gives us more flexibility in our small artificial pond project. For in our shopping we may stumble upon just the right statue -- and at a cheap price -- only to find that it wasn't designed to house water fountain plumbing. In the picture to the left, you'll see the solution to this problem. For my artificial pond I had purchased discount plastic statuary -- a boy and girl holding a basin -- that was designed sans plumbing. So I simply drilled one hole in the bottom of the statue, and another near the top. With an Exacto knife I expanded the holes so that they'd be large enough for me to feed plastic tubing through. I used 1/2" plastic tubing, because the discharge adapter on my pump is 1/2" (the discharge adapter is the little "pipe" coming up out of the pump's hole, through which the water is pushed out). With the plastic tubing fed through the statuary, the excitement begins! For now it is time to bring your decorative water fountain statue over to the preformed pond liner. Fill the pond liner with water. Place the pump into the water, without plugging it in yet (keep the plug end over by its outlet, so that it will stay dry). The Little Giant submersible pump model that I mentioned (Page 1) should always be submerged when it's running -- otherwise, it will overheat and you'll damage the pump. Now take the end of the plastic tubing that's hanging out of the bottom of the statue, and fit it over the pump's discharge adapter. Situate your water fountain statue wherever you planned for it to stand. In my pond's design the statue sits on the rim of the pond liner (half over the water and half over the ground). And now for the moment you've been anticipating. Take the pump's plug, and plug it in to the outdoor outlet. Enjoy gazing at that first jet of water, shooting up into the sky. After this initial enjoyment, you can go back to work, adjusting the way you've situated your water fountain statuary, so that the jet goes where you want it to go. If the jet drops at the edge of the water, rather than in the middle, you'll lose water faster. Too much of the falling water will splash out onto the ground. The faster you lose water, the sooner you'll have to refill the pond. With these adjustments made, you're ready to incorporate decorations to enhance the beauty of your outdoor water fountain. Besides water garden plants and additional statues, decorative rocks placed in and around your new outdoor water fountain will dress it up considerably. If you've made a habit over the years of bringing home pretty rocks, this is the time to put them on display. Rocks and water complement each other. If a nice rock specimen looks pretty when it's dry, just get it wet -- and it becomes spectacular! FOUNTAIN EXAMPLES PUMP/PLUMBING TIPS Plumbing your pond is necessary to provide a fountain or waterfalls, and also to add pond filtration. From a cost standpoint and for ease of installation, buying a single pump to power both a waterfall and the filtration system is recommended for most ponds over 4' x 5' in size and less than about 25' x 30'. Hopefully, you will find the following suggestions and comments regarding pump installation to be helpful. These suggestions are by no means the only way to accomplish your job, but in general they will solve many of the commonly found problems and help you prevent many others. Please note that Sequence pumps are out-of-pond pumps. Do not submerge! STEPS 1. Locate the pump as close to the source as possible. It is best to have your main (longest) run of pipe on the discharge side of the pump. The pump is designed to push water, not pull it. 2. Install the pump outside the pond, and if possible below the level of the surface of the pond (flooded suction). This will help insure a proper supply of water to the pump. Remember, a pump can’t pump out water if there isn’t any available. Even if your supply line comes up and over the top of the pond wall, it will still offer a flooded suction if it has no breaks to atmosphere before it goes back down below the surface level, and if all air is removed. 3. If it is not possible to provide a flooded suction installation then: Position the pump as low as possible, and as near the source as possible. (A pump one foot above the surface works better than one six feet above the surface.) Install basket strainer on the inlet of the pump or provide some other priming source. a) Suction piping should slope gently upward to the pump or strainer inlet. b) Install a foot valve, or a check valve in the inlet line below the water level. c) Always prime the entire inlet line, basket strainer, and pump before turning it on. d) If your pipe has a high spot (as in lower right illustration), install a tee at the highest spot and use this spot to prime the suction line, (or to bleed off air if pump is higher than the tee) 4. Always have your inlet pipe diameter equal to, or larger than, the discharge line. This helps prevent cavitation. 5. Minimize friction losses by using large diameter pipe. Determine the approximate flow rate you want, and the total length of your pipe. Consult the “friction loss chart” mentioned earlier to choose the proper diameter pipe. (The size of the pump’s suction and discharge ports does not indicate your proper pipe size.) Choose a pipe diameter that keeps your friction loss below about five feet per hundred feet of pipe. Even if you have a section of small diameter pipe that you can’t change, as with a through the wall fitting, it is still beneficial to use larger pipe on the majority of the run. The following chart can help you determine your correct pipe diameter. 6. Use a filtration system that does not require a lot of pressure. It costs money to create pressure. Biological filters work well and require very little pressure. 7. Never allow an out-of-pond centrifugal pump and motor unit to become submerged. Use a GFI circuit for protection. If this ever accidentally occurs, shut the unit down, disconnect it, and have a reputable service shop examine the motor before re-using it. 8. Never run a pump dry. This may damage the mechanical seal and impeller. They are designed to pump fluid, not air. Insure the pump is full of water before you turn it on, and that it doesn’t out pump the supply. Note: if you have purchased a dry run seal, it can run without water for a limited period of time. 9. Cover the pump and motor unit with a suitable shelter. When protected from rain and dust the motor will last longer. The covering should allow the motor to have suitable air recirculation for proper cooling. 10. If your pump is producing too much flow, you can reduce the flow by partially closing a valve on the discharge line. Never restrict the inlet!!! Always allow a couple gallons per minute to flow to prevent heat build up inside the pump housing. 11. If more flow is required than a single pump can produce, consider using two or more pumps in parallel. This also offers the benefits of being able to vary the flow rates, insure partial flow if one units needs servicing, and can often save a substantial amount of electricity compared to using a single, larger pump. 12. Choose a pump that can give you the required flows at the lowest possible power consumption. Since pumps often operate continuously, the power consumption (watts - not amps), and its effect on your monthly utility bill can be very significant. 13. Check to be sure the motor electrical connections are set up to match the supply voltage. 14. Install shut off valves before and after the pump, so you can easily remove it from the line without having to drain your system. Be sure to use ball valves, as they have low friction loss characteristics. 15. Use Teflon paste (not tape) for sealing threaded joints. 16. Make sure all your pipe joints are airtight. This is especially important on the suction side. INSTALLING LIGHTS An underwater light in your fountain or pond adds character to any garden pond, pool, or fountain. It gives the needed light at night to make your house more attractive and stand out on the block. Choose a light that best highlights your water structure. Giving an area less lighting that is needed will not bring out the best of the area that you are trying to light. Some lights are sold with colored filters that create a dramatic lighting effect. Underwater lighting systems usually are low-voltage systems and are relatively safe and easy to install. Leave installation of more elaborate 120-volt lighting to a professional, unless you are an electrician TOOLS NEEDED Screwdriver Combination Tool Electrical ties for tying up excess wires MATERIALS NEEDED: Underwater light Cable Crimp-on connectors Concrete block Underwater lights usually are sold with the light, fixture, and cable in one package. Check the package to make sure it has all the necessary items before leaving the store if the package is already opened. The pre-fabricated concrete block that anchors the light to the bottom of the pond, pool, or fountain is made especially for the job and is sold separately. The cable is attached to a transformer that reduces regular 120 voltages to 12 or 24 volts. Plug the transformer into an outdoor GFCI receptacle. You can purchase this receptacle at any home improvement center also. Because you probably won't want to keep plugging in the unit, especially when it gets cold outside, place a plastic waterproof cover over the receptacle to keep it plugged in and protected all season. Most transformers have a switch that turns the light on at a preset time. Using color lights will make the fountain, pool or pond more attractive. You can buy the special bulbs and filters for your project at your local home improvement center. Make a connection between the underwater light wires and the transformer. With the type of transformer shown above, attach crimp-on connectors by squeezing them onto the wires with a combination tool. Then screw each lead to the appropriate terminal on the back of the transformer. Assemble the light fixture according to directions in the package, if necessary. A concrete block usually anchors the light in the water. Bore holes in the concrete block for lead shields, and then screw the light's mounting bracket to the shields. Put the light in place and plug the transformer into an outdoor GFCI receptacle. If there is no place to attach the outdoor receptacle to, use a piece of 4x4 outdoor post and cut it. Attach an electrical box by doing this: Place the post in the ground and attach the receptacle to it. This way the post with the needed electrical is right near your pond, fountain or pool for servicing, if need be. This project should take around 2 or 3 hours to complete. You can now add exotic fish to your pond and have them on display at night. TIPS FOR SUCCESS 1. Install underwater lights directly below a waterfall or fountain. Aim light in the same direction as the water’s motion to highlight it. 2. Install ground lighting to that it shines away from the observer. Pathway lights should focus on the ground or nearby plants or ornaments and present no visual glare. 3. Low-voltage underwater bulbs are typically 20 watts; low-voltage garden lightbulbs are usually 10 or 12 watts. Underwater and garden bulbs may be used interchangeably. However, if you are using a low-voltage garden light set that powers six ground lights and decide to add one underwater light, you will have to cut back to only four of the ground lights to avoid overloading the circuit. 4. Avoid directing lights to shine on the water’s surface—this creates glare. Use the water as a reflecting pool by leaving the surface dark and lighting the surrounding landscaping instead. 5. Periodic cleaning of submersible light lenses keeps them performing at their best. 6. Install lighting around your water feature before you finish landscaping, such as laying sod or adding mulch or gravel. 7. Spotlighting an unusual specimen such as a night-blooming tropical water lily shows off its special attraction. Avoid spotlighting a night bloomer from below; more subtle side lighting works better. 8. If a low-voltage light fails to work when you test the set, check to be certain that there is contact with the power cable. 9. Mount the transformer to a vertical stake that is set in concrete for stability. 10. Low-voltage lighting works best in small gardens because each lamp lights a small area. Standard-voltage systems prove more valuable in areas where brilliant illumination is required for safety or security. ADDING EDGING With the pump and filter in place, all that's needed complete the pond's hardscape is the edging. • For a natural look, you can select various shapes and sizes of rock, working from the waterfall to the opposite end of the pond (figure A). Tip: The more weathered the stone, the more natural its appearance. • The pond's flagstone border serves two purposes: 1) To conceal the edge of the liner and visually integrate the pond into the landscape and 2) To protect the liner from damaging UV rays that can weaken it over time. Tip: Stones of numerous shapes and colors are often included in Japanese gardens, where they represent water flowing from the mountains, islands in the sea or the transition from sea to land. • Once the entire border is in place, remove two of the flagstones to create an open area (figure B) that can be filled with soft grasses during the planting phase (featured in the next episode). Tip: Creating an opening in the border also makes filter and pond maintenance easier. • Finally, add shims -- small pieces of rock -- beneath the edges of the flagstone pieces to elevate their edges and make them more level (figure C). • The finished result is the beginning of a picturesque, serene water garden that adds beauty, character and dimension to the property (figure D). OTHER EDGING METHODS For most Installations having a necklace of stone around the pond or water garden does not create a natural appearance. If your goal is to make your pond blend into the landscape in a natural setting then you will want to consider other methods of edging the pond. Besides the traditional method of edging with a thin stone on the edge overlapping the pond you can also use one or more layers of stone built up from the shelf. This provides a more natural appearance and will allow the water to fluctuate without seeing the liner. You can also create a cobblestone beach edging by placing a large stone at the inside of a large shallow shelf and filling the area with gravel and cobbles. You can naturalize this area by planting shallow water plants. This will create a more natural edge with plants partly in and partly out of the water. You can plant bare root plants directly into the gravel or place the plant with some soil still attached into the gravel. This will help the plant to establish quicker. GENERAL MAINTENANCE While inspecting your pond, also take some time to think about the variables that affect your pond as an ecosystem. Like all other types of ecosystems, ponds will be affected by local climate and seasonal variations. Some examples of these environmental influences include: greater leaf inputs from vegetation in the fall, possible freezes in the winter, and increased biological filter load in the spring time. Fluctuations such as these and other environmental variables will influence your maintenance load. Here are some ecological variables to take note of and to keep in mind: • Determine what the climate of your region is. Does your pond freeze in the wintertime? Are summer temperatures so extreme that evaporation losses are plentiful? How do the different seasons affect your pond? • Determine the amount and types of vegetation both within and surrounding the pond. Is surrounding vegetation deciduous or evergreen? How much leaf fall gets into your pond? Is your pond mostly for keeping plants? Are surrounding tree roots affecting the pond shell? • Is your pond typically in full sun, partial sun, or is it well shaded? • Determine the fish load of your pond. What kind of fish do you have? Is your pond stocked with mostly koi, goldfish, mosquitofish, or some other types of fish? • How is the water quality of the tap water of your region? Is the tap water treated with chlorine or chloramines? Is your pond fed by spring water? • Do predators such as raccoons and herons visit your pond? • Does your pond receive any water runoff from the yard after rainfall or yard irrigation? • Take note of any other kind of environmental variable that you may think affects the ecosystem of your pond. Now that you have taken some time to inspect your pond and its ecology, let us now focus on the actual task of maintenance. The first duty that needs to be addressed from a maintenance standpoint is general debris removal. Leaf fall and fish wastes are the main sources of debris inputs and they are most efficiently removed by a combination of netting and filtration. Without this combination, a pond will begin to accumulate debris in the form of organic sludge, which can allow unwelcome anaerobic bacteria to proliferate. On top of which, debris buildup can also clog pumps, filters, and plumbing which will minimize water and dissolved oxygen flow through the system. Netting out of debris is optimally performed by using skimming nets for the floating leaves and deeper leaf rakes for floating and sunken debris. Ponds can also be equipped with surface skimmers that can automatically remove floating debris that become trapped in their intakes. If your pond is equipped with a skimmer, be sure to keep the intake basket clear of debris to keep it functioning properly. It is also advised to trim the dead leaves and flowers off of surrounding and internal vegetation to keep your pond looking good and debris levels down. Well-designed ponds are also equipped with various types of filters to help deal with smaller debris inputs. There are three types of filters: mechanical, biological, and chemical, and all work to improve the quality and clarity of your pond water. These filters need to have a good supply of water flowing through them in order to function properly. To ensure this good flow, make sure that the pump intake or settling chambers are kept free from debris. Once supplied with ample flow, your filters can function optimally with the mechanical filters trapping larger debris, biological filters converting dissolved fish wastes, and chemical filters helping to trap dissolved impurities. Due to the overwhelming variety of filters that exist, steps to maintain these different types of filters can only be generalized at best. It will eventually be up to your inspection of your filtration system to determine the best course of maintaining them. The filtration media within all of the filter types will help to prevent larger debris from flowing back into the pond with their different media types. Over time, debris will begin to collect in these filters, which will need to be removed in order to keep the system functional. If the filter media is padding, cartridges, or some other type of easily removable media, take it out of the housing and rinse off the collected debris. Submersible pond filters should be maintained the same way by being rinsed outside of the pond. Filters with smaller media such as rock or beads, will need to be back-washed in order to be cleaned. Pressurized filters typically have a valve that performs this function while the non-pressurized variety needs to be back-washed manually. If you do have a non-pressurized, external, small media filter in your system, be sure to reverse the flow and manually stir up the media to help prevent circulating water from channeling. Make sure that none of the rinsed off debris gets back into the pond. Remember to also replace the media within the filters once they appear to longer be functioning. Signs of media needing to be replaced will be obvious when it seems as if the media gets clogged too rapidly or media is falling apart. Chemical filter media will also need to be replaced at regular intervals depending upon the media type. Consult your local garden pond specialist for recommended media change intervals for your particular filter. As mentioned before, it is critical for the filters to receive adequate flow in order to perform their functions. Most typically, circulation pumps provide that flow, and they are located either within or outside of the pond. Each type has their own advantages and disadvantages, but the out of pond variety are relatively much easier to maintain when equipped with an intake basket. These baskets not only hold more debris than most submersible pump intake screens, but can also be more easily accessed for debris removal. Removal of debris from either type of intake can be done manually for the larger particles, and with a hose for smaller ones. Another aspect of pond maintenance that needs to be focused upon is the aesthetic and functional consequences of some key environmental inputs. Ponds that are full of nutrients from fish wastes and organic debris can potentially break out in a green algal bloom. This is more typical of a newer pond or a pond without biological filtration, but it can be remedied by other means if need be. Installation of an ultra-violet clarifier can control such an outbreak, but periodic maintenance to replace the bulb will be necessary. However, these clarifiers do not do anything about the filamentous, or hairy algae, which typically is found on the base of waterfalls. This type of algae must be removed manually with a brush, stick, or some other sort of tool to twirl it out with. One final item to consider is the health of your fish. Your fish live in your pond and rely on you to perform maintenance and to take care of them. Ponds with fish need to be equipped with a biological filter to help convert the toxins that they excrete and these filters need to be maintained in the way mentioned earlier. On top of which, you will need to feed them and keep an eye on them to make sure that they are healthy. Fish should be fed less in colder months than in warmer months and their diets are seasonally dependent. Foods high in protein should only be used in warmer months where as a low-protein diet should be used in colder months. Testing your water on a somewhat regular basis will also allow you to make sure that the pond water is safe for your fish. Make sure that ammonia and nitrite levels are low to non-existent, test for pH, and monitor your fish for any signs of infection. Be sure to also treat any incoming fill water from your tap if there is any chlorine or chloramines in it. Your local pond specialist or fish store can further address any of the health concerns you may have for your fish. As you can see, all of the maintenance tasks mainly consist of debris removal from within the pond and its internal components. By regularly netting out larger debris, trimming decaying aquatic plant matter, and filtering and removing small and dissolved particles, your pond should remain aesthetically pleasing and fully functional. Your maintenance load, i.e. amount of debris inputs, will vary depending upon various environmental influences, and so it is best to adjust your approach accordingly. Overall, keep in mind that the task of maintenance is an easy one as long as it is performed regularly. In return, the process will benefit all who visit the pond and your fish will love you for it. SEASONAL MAINTENANCE SPRING As spring approaches, here is a list of pond care suggestions to help get your pond off to a healthy start for the spring and summer growing season. • Increase water circulation. • Start feeding your fish again when the water temperature reaches a constant 50 degrees. If there has been an accumulation of leaves and other debris over the winter you should remove this now. Leaves can be removed with a skimmer type net that has a square end that allows you to push this across the bottom of the pond scooping up the leaves. You can also use the Leaf Eater Vac or MiniVac for smaller ponds and small leaves to vacuum the leaves from the bottom of the pond. These devices use fresh water from your garden hose to create the suction. You could also try to use a shop vac but this removes a lot of water in the process and may not be the best choice. If there are lots of leaves and sludge accumulated in the pond to the point that you cannot remove this easily a complete pond cleaning may be necessary. A complete cleaning will upset the balance of the pond and actually interfere with algae control but should you decide to go this route you can use the following method. Pump water from the pond into a large tub or other container. The exact size will depend on the number and size of fish that you have but should be as large as possible. It may be necessary to cover the container with leaf netting or something similar to keep the fish from jumping out especially if you have koi. This container should be in the shade if it is hot out. Continue pumping the water out of the pond until it just covers the fish. Use a fish net to catch the fish and place them in the container with the water just pumped from the pond. Also the plants can be removed if repotting is necessary or left in the pond. If removed they should be kept in the shade and covered with damp newspaper. Underwater plants should be kept in a container of water. After you pump as much water out of the pond with your pump as you can, you will want to use a shop vac to finish up or you can use a large dustpan and broom with a bucket to finish removing the sludge. Do not try to scrub the velvet type algae that may coat the liner as this is beneficial. Do not use any chemicals. After the pond is clean you can pump the water with the fish into the pond and then put the fish back into the pond. Add a dechlorinator to remove the chlorine and slowly add water from the hose to finish filling the pond. The plants can be placed back into the pond during the filling process. After the pump and filter are turned back on it is a good idea to add bacteria such as Biological Clarifier, BioFilter Booster, Microbe-Lift PL, or Microbe-Lift Spring/Summer Cleaner, to help in establishing the balance of the pond. Acclimate fish. • Fertilize each plant and place at appropriate depth. Lilies and Lotus should be fertilized every 3-4 weeks, marginals every 5-7 weeks. • Add Anacharis to prevent algae growth. Use one bunch per one sq. ft. of surface area for ponds under 50 sq. ft. and one bunch per two or three sq. ft. for ponds over 51 to 200 sq. ft. For ponds over 200 sq. ft. use one bunch for every three to four sq. ft. • Turn on Ultraviolet sterilizer after the biological filter is working properly and the water starts to turn slightly green. • Add Pond Pond-Zyme or Microbe-Lift PL (these products contain bacteria to help jump-start biological filters and break down sludge). • Divide and repot plants as needed. • Add floaters such as water hyacinth and water lettuce (late spring after danger of frost has passed). • A few things you may need: Fish net, Dechlorinator, Biological Clarifier, Anacharis, no-hole aquatic plant containers, Aquatic Plant Soil, gravel, fish food, and a thermometer. SUMMER • Remember to continue fertilizing your plants. • Remove dead foliage from the pond. • Feed your fish well. • Maximize your aeration. AUTUMN/WINTER One of the most significant events of Fall is, of course, when leaves begin to fall from the trees above. If these leaves get in the pond and decay it will throw off the ecological balance of a water garden. One option is to use a net to skim leaves off the surface of the pond as they fall, but this can be a daily chore. Also, don't expect a skimmer type filter to get the leaves. Skimmers are designed to get the occasional leaf or other floating debris. Heavy leaf fall can clog a skimmer several times a day. Installing leaf netting over the pond will be easier to maintain. It is best to try to minimize the amount of accumulated sludge, decaying plant debris, etc. from the water. This can be done with a net, by siphon, or by use of a pond vacuum, like the Mini-Vac or the Leaf-Eater. FISH The water temperature is dropping now and we should be feeding our fish less as their metabolism slows down. Hopefully you have been feeding your fish well with a high protein food this summer to allow them to build up a reserve of fat to help them through the winter. After the water temperature drops to the sixties you should decrease the amount of food given and feed only once a day. Provide food with a protein content of 25 to 32 percent. A wheat germ based food is good at this time as it is easily digested. Pond Care's Spring & Autumn Food is an excellent food at this time of year. It is formulated with a unique blend of amino acids and minerals to help supplement the dietary requirements of koi and goldfish in cool water. As the water temperatures continue to drop to below 60 degrees you should feed only two or three times a week. It can take your fish two or three days to digest food at this temperature. Once the temperature drops below 50 degrees you should stop feeding altogether until spring when the water temperature remains above 50. As organics decompose in the pond they can produce toxic gases that could be trapped in the pond if it is covered by ice for more than a few days. It is important to keep at least a small area free of ice so that these gases can escape. Do not break the ice as the shock waves created can damage or kill your fish. One of the easiest ways to do this is with a floating pond de-icer. This device floats in the pond and has a built in thermostat to turn the heating element on when the water temperature drops below 40 degrees. They can also be used to keep a small pond from freezing solid allowing you to keep your fish alive. With their slower metabolism and the absence of plants our fish are more susceptible to predation by raccoons, birds and other animals. If you took our advice and added leaf netting to keep the leaves out of your pond this should protect your fish as well. A Koi Kastle will help your fish be more comfortable by providing a place for them to hide. One of the most effective methods of keeping predators away from the pond at any time of the year is the ScareCrow. This device senses movement with a motion detector and sprays any intruder with a burst of water frightening them off. PLANTS You should have stopped feeding your plants by now. As the foliage on your hardy plants begins to die back you should remove any dead and dying leaves and place the plant deep enough in the pond to keep the roots from freezing. While it is true that some marginal plants will survive even if their roots freeze solid it is best to lower all of your plants below the ice zone. If your pond is too small or shallow to offer protection from freezing temperatures then you still have other options. You can add a floating deicer, which will keep the pond above freezing. If your pond is not too large and does not contain any fish you can place a cover such as plywood over the pond and cover this with bags of leaves or bales of straw to provide insulation. A tarp should also be placed over the straw to keep it dry to provide better insulation. A basement can provide protection if you remove the plants and store them either in their original containers or in peat moss. A method that I like is to build a temporary shelter over the pond. Lumber or PVC pipe can be used to construct a framework over the pond. Place clear plastic over this and weight the plastic down with soil or stone. This frame should hold the plastic a few feet above the water. Greenhouse type plastic is best but construction grade plastic should last the winter. This method works very well and is basically like moving the pond to one USDA hardiness zone higher. On clear days the sun warms the water and even if covered with snow there is good insulation over the pond. Some tropicals can be wintered over this way in mild winters even if you live in zone 6 or 7. Some plants do not like being submerged in the pond through the winter. Iris ensata formerly know as Iris kaempferi a Japanese Iris should be removed from the pond and planted in the yard until spring when new growth starts and it can be placed back in the pond for the summer. Lobelia cardinalis (Cardinal Flower) should be removed from the pond and planted in the yard for the winter. This plant should have a few inches of mulch over it as well. You will have more success wintering over Cannas if you remove the rhizomes from the pot and store in slightly damp peat in a basement or other cool area. Some tropical water lilies will bloom all winter if kept in a tub container inside and given at least six hours of bright light. You can also winter them over by removing the tuber from the pot after the foliage has died back from a freeze. Place the tuber in a container of slightly damp sand or peat moss at 50 degrees. In the spring you will need to heat the tuber in an aquarium to about 75 degrees to trigger its growth before moving outside. One choice with tropical plants is simply to dispose of them after freezing weather and replace them in the spring. This way you get to try new plants and colors next season. If you want to try wintering over your tropical plants there are a few methods worth trying. Many tropical plants can be brought inside and treated as a houseplant for the winter. Umbrella Palm, Taros, and Calla Lilies will do very well with medium light levels. If these are in no-hole containers then no special care is needed otherwise keeping the pots in a tray full of water is needed to keep the plants wet. Water hyacinths and water lettuce require more care than they are worth; it is much easier and less expensive to replace them each spring. If you still want to make the effort they require 10 hours of intense light and temperatures above 70 degrees. PUMPS AND FILTERS Depending on your climate and other factors you may or may not want to run your pump and filter system through the winter. If you live in a climate with temperatures mostly well above freezing then it will be to your advantage to keep your pump and filter running through the winter. The bacteria in your biological filter will not be active at low temperatures but it will remain alive as long as you keep it supplied with oxygen-laden water. When spring arrives and the water temperature is rising the bacteria can start to work immediately keeping the water quality good for your fish and helping to control the algae. Should you choose to run your filter through the winter it is a good idea to minimize the water circulation in order to take advantage of the layering effect of the water. (Water temperature is densest at 39 degrees and the water on the bottom of the pond will remain at this temperature even with freezing temperatures on the surface.) Some ways to minimize circulation is to turn off bottom drains if possible, place intakes to pumps/filters at mid-water, turn off surface skimmers, (you do not want to circulate top or bottom water in the winter), place your intakes closer to the outlets in the pond (waterfall or fountain), and or turn the pump down. These actions will allow the biological filters to stay alive without interfering with the layering of the water. Massive circulation of water in the winter can super chill the water by exposing warmer pond water to below freezing temperatures leading to the death of the fish. One problem with running a pump and filter in the winter is the potential of major damage to your filter and plumbing system if the power goes off for extended periods and you are not at home to make sure that no water is present in the filter and plumbing. If water is allowed to freeze in plumbing, UV's and filters this can lead to breakage requiring replacement of these units. If your system is designed to allow the water to flow back into the pond in the event of a power outage then these problems can be averted. If you have a check valve installed in your system you can use a long piece of small tubing or wire to hold the valve open to allow the water to drain out. You can turn off the pumps and filters for the winter. Cold water holds much more oxygen than warm water and the fish's respiration is slow therefore you should not need the circulation and aeration. The bacteria in your biological filter does not work in cold temperatures so the only reason to run the filter is to keep the bacteria alive. If you turn off the pump and filter for the winter be sure to drain all plumbing. External filters, UV's, and external pumps will need to be drained. Submersible pumps should be left in the pond or in a bucket of water in a warm place to keep the seals from drying out. If you choose this method be sure to clean the filter before starting up in the spring. With the absence of biological filtration you may want to add Microbe-Lift's new Autumn Prep which contains bacteria that will work in near freezing temperatures and it also contains enzymes that consume cellulose in the form of leaves. AUTUMN/WINTER CHECK LIST • Before the leaves begin to fall, cover your pond with one of several sizes of leaf netting. (It is much easier to keep the leaves out than to remove them after they fall into the pond) • This is a good time to divide some types of aquatic plants (water lilies and iris) • Remove tropicals from the pond as they will decay and pollute the water. • After your hardy plants have stopped growing, cut back the foliage and lower the pot to the bottom of the pond. • Stop feeding your fish after the water temperature has dropped to the mid to upper forties. • Also when the water temperature has dropped into the forties, reduce the circulation of the pond water by either turning off the pump for the winter and draining of all the plumbing or preferably by placing the pump or the intake to the pump closer to the water outlet (waterfall etc.) and pick up water from mid-level of the pond. Also turn down the water flow. Keeping the water flowing through your biological filter allows the bacteria to live therefore giving good water quality early in the spring. • If you keep your filter running through the winter, you must take precautions against the freezing of water in your plumbing should there be a power outage. • You can add a floating de-icer to keep an area free of ice. This opening is necessary during periods of ice cover to allow an exchange of gases. Water Hawthorns are a nice addition to the pond and sometimes bloom through the ice. They grow and bloom fall through spring and go dormant in the summer. • POND PLANTS If we want a pond for keeping ornamental fish or for having the sound of running water then a water garden in the shade is fine, however if one of our major reasons for having a pond is to be able to grow all of those glorious water lilies and other luscious plants then we want as much sun as possible. Sometimes we have no choice but to place our ponds in areas of little or no sunshine, or perhaps the pond was placed in the shade before the importance of sun was realized. For those situations, our plant choices may be limited but beauty can still be obtained. Most aquatic plants require at least 4 - 6 hours of direct sun to flourish, there are however, several varieties of water lily, marginal, and floating plants that will do well in partial shade (3 - 4 hours of direct sun). WHAT ARE THEY? Water garden pond plants breathe somewhat differently to us. Typical pond plants breathe in carbon dioxide during the day (and breathe oxygen out) Pond plants breathe in oxygen during the night (and breathe carbon dioxide out). All garden pond plants behave as follows in a pond and are thus able to add real value to that environment: • Garden pond plants convert carbon dioxide in the atmosphere to oxygen in the water and use this carbon dioxide to produce energy in the form of sugars - photosynthesis. • All pond plants consume nitrogen chemicals (mainly nitrates and phosphates) that build up in the water. Watercress is often used for this purpose. • Garden pond plants have a limited filtering effect. • Some pond plants are particularly good at oxygenating the pond water • Select plants for around a pond to blend in with the garden pond. Refer to the diagram in the aquatic plants link above left to see a diagram that will help you decide on plants for around a pond. It is recommended that you plant aquatic plants in Fabric Pond Pots or no-hole plastic containers to minimize maintenance. Use a heavy clay loam (not potting soil) or a packaged soil specific for aquatic plants. Using the wrong type of soil can cause numerous problems. Most aquatics require at least 5 hours of direct sunlight for optimum growth. Do not cover the growing point of water lilies with soil or gravel. TYPES Tropical Water Lilies Day and night blooming- tropical water lilies should be planted in pots at least 10" in diameter (a smaller container will result in a smaller plant). A 2-5 gallon size should suffice for each lily. Fill the pot 1/2 full with a loam garden soil and add 2-4 fertilizer tablets, then continue to fill the pot to about 2 inches from the top. The tuber should be set upright with the roots buried gently in the soil. Make sure the tip of the tuber is not buried. Next, add an inch or two of pea gravel or sand in order to prevent the soil from escaping from the container. Remember to keep the gravel away from the crown of the tuber. The plant can now be lowered into the water to a depth of approximately 6 inches over the crown of the water lily. As the plant grows, it can be lowered to a depth of 12 inches. Tropical water lilies cannot tolerate cold temperatures and should not be planted until the water temperature reaches at least 70 degrees. Planting too early can cause dormancy and restrict the potential growth of the plant. Tropicals bloom from late spring through early fall, depending on the weather. Fertilizer tablets should be added every 3-4 weeks. ALBERT GREENBURG WATER LILY • • • • • • Hardy Zones: 10-11 Planting Depth: 6-18" over crown. Spread: 4-6 square feet.

Hardy water lilies are planted in much the same way as the tropicals using a loam garden soil and 2-3 fertilizer tablets. Hardy lilies grow horizontally across the container so a wide pot is necessary for planting (a 14" or 16" fabric pot is the best container). The rhizome should be planted at one edge of the container with the rhizome planted at an angle of about 45 degrees with the crown exposed. Top with an inch or two of pea gravel or sand. The plant can be lowered to a depth of 6 inches to begin with, and then lowered to a depth of 12 - 18 inches as the plant grows. Hardy lilies should be planted in early spring and should be fertilized every 4-6 weeks. They bloom from June through September depending on the weather, and become dormant during the colder months. As spring approaches, growth will begin again. ATTRACTION WATER LILY • • • • • • Hardy Zones: 3-11 Planting Depth: 12-15" over crown. Spread: 6+ square feet.

Marginal (Shallow Water) Plants • • • • • • Marginal plants should be planted in individual containers of approximately 1-3 gallons. The marginal plants which are grown in 2 " net pots should be planted without removing the net pot so as not to damage the roots. Plant as you would the lilies in a loam garden soil, but when adding fertilizer tablets, use 1 tablet for each gallon of soil. These plants should be fertilized about every 6-8 weeks. Marginal plants should be lowered to a depth of only 2-3 inches. They grow out of the water and are usually found at the water's edge. ARROW ARUM • • • • • • Hardy zones 5 - 9 Growing height: 12-24". Planting depth: Top of the pot should be 0-5" below the water surface. Thrives in full sun to shade. White arum-like flower in summer. Arrow-shaped leaves that produce arum-like flowers give this plant its name. ARROWHEAD • • • • • • Hardy zones 5 - 11 Growing height: 18-24". Planting depth: Top of pot should be 0-4" below the water surface. Thrives in full sun to partial shade. White flowers in summer. This plant's arrow shaped leaves can grow up to 18" long. BACOPA • • • • • • • BLUE PICKEREL RUSH Hardy zones 6 - 9 Growing height: 4-8". Planting depth: Top of the pot should be 0-6" below the water surface. Thrives in full sun to partial shade.

Thrives in full sun to partial shade. White flowers in late summer. • • • • • CANNA • • • • • Hardy zones 5 - 11 Growing height: 5-6'. Planting depth: Top of the pot should be 0-10" below water surface. Thrives in full sun to partial shade. Small clusters of violet flowers are held high above the foliage in summer. Floating Plants These plants require no planting. Simply place them in the water and they will grow. Many floating plants desire tropical temperatures and cannot tolerate a frost. BUTTERFLY FERN • • • Hardy Floating plant (per portion) One portion equals approximately 1/2 cup. Makes a good fish treat. FAIRY MOSS • • • Hardy Floating plant (per portion) One portion equals approximately 1/2 cup. Makes a good fish treat. FROG BIT Underwater Plants All ponds should have underwater plants to aid in maintaining clean and pure water. These plants help prevent algae growth. These plants can be potted in one-gallon containers with pea gravel to hold them in place or they can be weighted and dropped to the bottom. Completely submerge these plants to a depth of at least 12 inches. ANACHARIS This Underwater Plant reduces algae's food source. Lily-Like Aquatics These plants grow similar to water lilies. They are rooted in a pot several inches under the water but the foliage grows to the surface and floats. Pot the same way as tropical water lilies except most are much smaller and only need a one gallon pot or an 8" x 10" fabric pot. Use one fertilizer tablet every 4 - 6 weeks. Lower the container to 6 to 12 inches of water over the top of the pot. Some of these are hardy and will winter over; others are tropical and are treated as tropicals. VARIEGATED FOUR-LEAF CLOVER Hardy zones 6 - 11 Planting depth: 6-18". Full sun to shade. • • • WATER HAWTHORNE • • • • Hardy zones 6 - 9. Planting depth: 6-18". Full sun to partial shade. Dormant in summer, white flowers in fall and spring. YELLOW FLOATING HEART • • • Hardy zones 5 - 10 Planting depth: 12-24" Needs full sun. POND FISH Fish bring both color and movement to your water garden. They also keep the mosquito population in check. Start with just a few fish; then gradually add more. Goldfish and koi are particularly popular because they are large, colorful fish that are highly visible from above. They are easily trained to take food from your hand. They grow quickly, are generally pest-free, and come in many bright, cheerful colors. Stocking a pond requires careful planning. Fish can’t tolerate the chemicals commonly found in municipal water supplies, so you’ll need to neutralize these chemicals before introducing fish to the pond. Also, choose fish with your climate and pool size in mind. Certain species fare better in certain climates and pool depths than in others. KOI VARIETIES Below is a chart differentiating the various classifications of koi, allowing you to learn a little bit about them. KOI HEALTH This is a very brief guide to some common koi diseases; it is in no way a substitute for a good book on the subject or professional help. Unless specifically stated most of these problems can be treated using commercial remedies, which state what they are for on the packaging. Ask the dealer for advice if you don't know which one to buy. Sliminess of the skin. A grayish white film of excess mucus on the body. This is a reaction to protozoan parasites, notably Ichthyobodo, Trichodina and Chilodonella. Other symptoms of infection by these parasites are scratching and leaping followed by lethargy and failure to eat. Further risks are secondary bacterial and fungal infections of wounds caused by scratching. The parasites are particularly active in spring when koi are still recovering from winter. White spot (Ich). Caused by Ichthyopthirius multifiliis. The white spots on the skin, gills and fins are individual protozoan cells that are under the skin and feed on the body fluids and cells. They then punch out of the skin and fall to the bottom of the pond, collect together and begin breeding, the offspring then reinfest the fish. As well as white spots symptoms are scratching and swimming into the water inlet, failure to feed and lethargy. It is fatal if untreated. Fortunately commercial white spot remedies are widely available. Anchor worm. Crustacean parasite, Lernaea . The juvenile stages settle in the gills of koi, when they mature they mate and the male leaves the koi, the fertilized female settles on the body of the koi and continues to grow, becoming the familiar worm shape. The female buries into the skin and underlying tissue to hold on. The damage caused can become a target for bacterial or fungal infection, which can spread. Fish lice. Argulus another crustacean parasite, round and up to 1cm wide. They have a sucker to hold on to the koi with needlelike mouthparts which they stick into the koi and inject a toxin. This causes intense irritation to the koi and they scratch and jump and can cause bacterial infection. If they infect the gills they cause severe damage and often death. Most antiparasite remedies will not kill fish lice; a strong chemical is needed which is not freely on sale. Ask a professional dealer or vet. Gill maggots. Are the mature females of the parasitic crustacean Ergasilus. Heavy infestations can cause severe damage, eroding the gill filaments and allowing secondary infections to develop. Skin and gill flukes. These are the fish equivalent of fleas. They are two different types of flukes, but despite of their names both can be found on the body and the gills, feeding on mucus. They use hooks to hold onto the koi, this causes irritation and in a weak, sick or stressed koi can become a problem. Saprolegnia fungus. One of the most common fungal infections of koi. The fungal spores will grow anywhere on the koi, including the gills, initially germinating on dead tissue. Their threadlike hyphae release digestive juices that break down the tissue so the fungus can absorb it, as the fungus grows these juices start breaking down living tissue. Fungus on the body appears as cotton wool like growths, it is hard to tell if a koi has it in the gills, but if it hangs at the surface gulping for air it is likely. Carp pox. A virus that produces solid waxy lumps on koi. It will not kill koi and is generally harmless, but can look unsightly. It is most often present in small koi and in cold weather, clearing up disappearing when koi grow and in the spring when water temperatures rise. Finrot and ulcers. A number of bacteria are associated with finrot, lesions and internal haemorrhaging, notably Aeromonas and Pseudomonas. Ulcers usually start at the site of an injury, the bacteria then infect it causing further damage, and fungal infection can also occur. Such holes result in osmoregulatory problems, leading to damaged kidneys and death if not treated. It is worth adding a weak salt solution to the pond as well as anti bacterial remedy, a concentration of 3gm per liter will help to restore the osmotic balance and reduce strain on the kidneys (make sure that the salt is fully dissolved before you add it to the pond). Finrot is easily noticeable, the fins and/or tail look chewed and are red at the edges. Secondary bacterial and fungal infections can develop. Cotton wool disease. Another bacterial infection. The common name comes from the white tufts that develop around the mouth and spread to the body and fins, often leading to ulcers and a thin appearance. Flexibacter is the bacterium, which causes this disease. Treatment with anti bacterial medicine is usually effective. Dropsy. Raised scales (rather like a pine cone) and eyes standing out from the head. A sign of a number of conditions may be congenital heart or kidney failure or an internal bacterial infection. Bacterial dropsy is infectious so treat with an anti bacterial remedy and if possible isolate affected koi. FEEDING Little and often is the best rule to follow when feeding koi. Koi will always take more than they could comfortably eat which can cause them to become unwell. Overfeeding will also lead to an increase in ammonia and nitrite which if unchecked could be fatal. Also, koi become bolder and tamer if they have worked up a bit of an appetite and will then hand feed. It is best to feed koi a properly balanced commercial koi food, which will have the right amount of nutrients, protein, fat, vitamins etc. In winter koi should not be fed if it is below 10 degrees C as the food may not be digested and go rancid in the koi's stomach. Wheat germ food is the best food for winter as it is highly digestible and therefore less likely to cause problems. In the spring a higher protein food can be fed so the koi's body can repair itself and start to grow. In the summer, when it is more than 20 degrees C a high protein growth food can be used. Certain foods can be fed to koi to enhance their color. There are proprietary brands with various additives such as carotene or spiraling. Carotene affects the red pigmentation and if used at a high concentration will even turn the white to pink! Spirulina is a type of algae also enhances the red but won't affect the white. Koi also enjoy livefoods as treats. They will get some livefood from grubbing around in the pond but can also be given foods such as worms and prawns and even tadpoles. The red pigment in prawn shells is also a good color enhancer. Another favorite of koi is lettuce. Large koi will strip a whole lettuce bare. Brown bread is another good treat, but if fed too much can make them fat. BREEDING It is not possible to sex koi which are less than about 10" long as they are sexually immature, and it can still be difficult when they mature as there will be the odd skinny female and fat male. Generally speaking though, female koi are plump (due to egg filled ovaries) with smaller pectoral fins and males are streamlined and more torpedo shaped. Males also develop breeding tubercles on the head and pectoral fins in the breeding season. These breeding tubercles are tiny raised spots and are difficult to see, they are occasionally mistaken for white spot (ichthyopthirius - see health). Left to their own devices koi (if they are more than 10-12") will naturally spawn in the early summer. A water temperature of about 20C (68F) is ideal and the koi will spawn 'en masse' (known as flock spawning). This will produce healthy offspring but generally poor colors, if you want to breed good quality fry you should choose the parents and put them in a separate pond (a kids paddling pool will do) put 2 or 3 males in with one female. If left in the pond most of the eggs will be eaten, and any fry that do hatch will usually be eaten too. If you want to save some fry to grow on you will have to move them to a tank or pond with no adult koi. It is very difficult to collect eggs that have been randomly distributed in the pond so it is a good idea to use spawning brushes, which the koi will spawn on. Place the brushes with the eggs on in the pond/tank you are going to rear the fry in and add 0.2mg/litre malachite green solution to stop fungus infection. It is preferable to add an airstone, as the developing eggs need plenty of oxygen. If you are going to filter the tank make sure the young koi will not be sucked into the pump, you could put a fine net around it, if you are not going to filter it do regular partial water changes (about 20% of the water). The day before hatching the eyes in the egg will have a shine to them, soon the koi will begin to wriggle and in a few hours break out of the egg. At temperatures of about 20C it will take 3 or 4 days for the eggs to hatch, it will be quicker at higher temperatures. It is very important that the fry have plenty of oxygen at this stage so an airstone is a good idea. After hatching the fry will stick themselves to the sides of the tank with a sticky pad on their heads for 2 to 3 days, then they will swim up to the surface and gulp some air which is forced into the swim bladder and enables them to swim freely. This is the time to start feeding them. Hard-boiled egg yolk is a good food for the first day or so; it has little dietary value but will increase the size of their stomachs. Newly hatched brine shrimp are also good, feed these for about a week and then the fry will be ready to eat special fry food (very fine powdered pellets). When they get to about half an inch feed them tiny pellets and increase the size of the pellets as they grow. Remember not to overfeed and check water quality regularly, fry are very susceptible to high ammonia levels and it is easy to lose them all if care isn't taken. GOLDFISH VARIETIES Common -- These are normally shaped fish. They can grow to be 12 inches and live 20+ yrs if cared for properly. They are often sold in pet stores as "feeder fish". Fantail -- They are usually a shorter fish with double tails and more round bodied. If they have long fins they are named veiltails. Comet -- These are more like the common goldfish but with longer fins and skinnier bodies. Lionhead (Ranchu) -- These fish do not have a dorsal fin and have a head growth. They are not long and slender but more circular in shape. Black Moor -- These fish are double-tailed and have telescope eyes. Oranda -- A lionhead with a dorsal fin and head growth. They are most commonly white in color with a red cap (red-capped oranda). Shubunkin -- These fish are more long bodied and best known for their white bodies and spots of color in shades of yellow, orange, blue and black. Pompoms -- Small growths called pompoms grow near their nostrils. These fish are a variety of colors. Telescope eyed -- These fish come in a variety of shapes; however, they have large eyes that stick out similar to a telescope. Pearl Scale -- They have a fatter shape with a bulging middle and their scales look as though a white pearl is beneath each one. Bubble eyed -- They have bubble sacs under each eye. They can be various colors. They usually are without a dorsal fin. GOLDFISH HEALTH As with koi, goldfish can experience any number of health problems. Below is a list of the most common types. Parasites. Parasites are by far the most common problem. If the parasites don't kill the fish the complications they cause will. A salt treatment will kill most (but not all) of the common parasites known to the ornamental pond. These include: Ich, Chilodonella, Costia & Trichodina. The parasites that a salt treatment will NOT kill are Flukes, Fish Lice (Argulus) and Anchor Worm. Parasites are mostly brought in by new fish that have not been quarantined and treated but can also be brought in by amphibians such as frogs. Most parasites cannot be seen by the naked eye and a mucus scraping is necessary to pinpoint the type of parasite present. If having a mucus scraping performed is impossible, the safest thing to do is treat the pond as if it had Ich and Flukes. Bacterial Disease. Bacterial infections often follow a parasitic infestation. Bacterial diseases can also be brought in by new fish. Infection results when bad bacteria, such as aeromonas and pseudomonas, build up and attack a fish whose immunity system is low. It can manifest in several ways. Fin Rot, Mouth Rot, Ulcers are common forms of the disease. It can also be an internal infection such as Dropsy or Septicemia. Toxic Water. If you suspect that anything toxic has been added to your water immediately do a major (80%) water change and don't forget to de-chlorinate the new water added. Hold some of the affected water aside for testing or test your water right away for ammonia, nitrite and pH. Any reading at all of ammonia or nitrites is not to be taken lightly. Beef up your biological filtration because the problem will return within a day or two and keep returning until the nitrifying cycle is in place. Virus. Viruses are the deadliest and scariest of all fish afflictions because they kill quickly and complete and often before you even suspect a problem. A new fish can be a carrier and clean out your entire population of fish. The only cure is prevention. Quarantine all new fish in a heated environment for at least 2 weeks before introducing them into your pond. Know the reputation of your fish dealer. Aeration Problems. Fish breathe dissolved oxygen in the water through their gills. If water contains inadequate amounts of dissolved oxygen the fish simply smother. Many water treatments such as potassium permanganate and AlgaeFix use oxygen when they work. "Oxygenating plants" give off oxygen during the day but then take it all back at night and on overcast days. Add aeration whenever treating your pond. Add long-term aeration (such as air pump, waterfalls, fountains) for ponds that are very still. FEEDING Goldfish are classified as cold water fish and do not need to eat a diet that is high in protein; however, they will do better with a diet high in carbohydrates. Goldfish are not picky eaters; however, the greater the variety they are offered the more active and colorful they will become. You should feed your fish once each day. Do not overfeed... Live foods. Daphnia, Brine Shrimp, Tubiflex worms, Meal worms, Wax worms, Blood worms (I recommend using bloodworms cautiously as they will burrow into the gravel). Staple foods. Shrimp pellets, flakes in a variety of types, algae wafers, etc. Freeze dried foods. Krill, Pacific plankton, brine shrimp, bloodworms, etc. Frozen foods. Brine shrimp, bloodworms, etc. Greens and Plants. There are many different types of plants to feed your fish. Mine have just loved Anacharis. Romaine lettuce is good too. Now these are only suggestions. I have given my fish pieces of cucumber and zucchini on a suction cup clip for years, and they absolutely love it. (If you have snails, they will find it through smelling and sit on it until it is gone. BRINE SHRIMP Some of the measurements may look a little "seat of the pants" but when you are trying to keep four 4Ft. tanks of goldfish fry going, plus working full time and writing society newsletters time to mess around with weights is scarce. First you need three containers to actually hatch the brine shrimp eggs in; I use old plastic sweet jars. These are approximately 4 inches x 6 inches x 12 inches high. You now require a larger container to sit these jars in. A plastic toy box or an old fish tank basically any handy box that will hold water. Fill the sweet jars up to their shoulders or ¾s the way up if they are straight, with cold water. My jars contain 4ltrs or 6 pints. Put the jars in the box and fill up with water until the levels match up. Set up an aquarium heater put in the box and brings the temperature up until the jar water is at 80 deg. C. Set up an air pump and using open air lines with no airstones (it is important not to use air stones as they will soon clog up and the air produced from them is not vigorous enough to keep the eggs moving through the water.) Aerate the water so that it appears to be boiling, add the salt into one jar. I use 3 Dessertspoons of sea salt, any salt will do except table salt because of the flow free additives put into it. Dissolve the salt and add the brine shrimp eggs, up to three teaspoons. Do not add more than this for a jar of this size; adjust the air so that you make sure the eggs are not settling on the bottom, any that do will not hatch. After 24 hours the shrimps can now be harvested. I use an old 2-pint pot and a plastic funnel. Place the funnel into the top of the pot and using a clean cotton cloth (handkerchief) line the funnel. Take the jar from the container removing the air line and let the mixture settle for 5 minutes or so, you should see egg casings from the hatching rise to the top of the jar and the live shrimps on the bottom above any unhatched ones. Move the jar into a position so that you can, using a length of airline, siphon the live shrimps into the cloth. You should end up with a red mass of shrimps in the cloth. Feed these to the fry, they should live in a tank at 65 deg F. up to 12 hours. I find that if you experiment you can feed the fry small amounts at a time so as not to pollute the tank. Any uneaten is best siphoned out. Obviously put the jar back in the container if you do not use all the shrimps at one time. Once emptied the jar is washed out and refilled to start again. If you add eggs to the second jar as you use the first you can have an endless supply. I would recommend not feeding goldfish fry brine shrimps after 12 days off the glass (free swimming) but to wean them on to a high protein fry food. Failure to Eat. Failure to eat can be a sign of disease or water quality problems. It could possibly show that the current food needs to be changed. Lack of feeding can be a sign of stress. Make sure to check on the fish from time to time. Overfeeding. Overfeeding will cause unwanted food to spoil in the tank and cause water quality problems. It will raise the ammonia and other products of decay and encourage disease. You will want to monitor your fish eating and see that you are not overfeeding. Problems associated with overfeeding can be helped with routine water changes, and regular aquarium care. Storing Food. Sunlight, heat and moisture can speed up nutritional breakdown in dry fish foods. You should not keep the fish food in the refrigerator as the food could become damp from the condensation. Dry fish food that becomes wet should be thrown out immediately. The reason is bacteria and fungus can grow rapidly and may cause food poisoning. You should use the opened containers of fish food within 2 to 3 months.
