July 2003 Getting Started - a reefing primer Part 2 in a Continuing Series by Moe Kirby (BRS President) Last month I discussed how to find good information on setting up a tank, and recommended a starting tank size. This month I’ll continue the discussion of setting up an example 75 gallon reef tank, using Dave Balch’s newbie questions to guide the discussion. Q: Do I need a sump? What is a sump? A: One of the first things to decide is whether or not to make use of a sump. A sump is simply a place to which water flows from the main tank and then is pumped back to the main tank. Now you’re probably asking “Why?” Well, a sump is a convenient place to hold equipment like a protein skimmer, pH probes, and heaters (I’ll describe equipment in a future article). It is also a great place to add supplements, calcium reactor effluent and occasionally place a bag of activated carbon or phosphate remover (for those who are into that sort of thing). No need to mess up the look of the show tank; hide all that stuff in the cabinet under the reef. Another added benefit of a sump is that the overall volume of water in the system is increased. More water frequently means greater stability and a greater margin for error. Sumps also can make water changes easier. Moe’s “Acrolog” – gift of Mike Accardi So how does that work with a reef tank? Those who use sumps frequently use an extra (often smaller) aquarium as a sump. The main tank – or “show tank” – sits atop the aquarium stand as usual. Beneath the show tank, a smaller aquarium is placed to receive water from the show tank via either an overflow or pump. A pump is then generally used to return water back up to the show tank. A nice little water circuit is established. There are numerous schematics available at the online discussion boards that show how sumps fit into the overall setup of a reef system. John Tullock also has some great diagrams and some excellent suggestions in his book, Natural Reef Aquariums. There are, however, some problems associated with sumps. Most leaks and floods in this hobby are associated with a sump or the plumbing involved in the water circuit. There are many opportunities for disaster with use of a sump, so careful planning, design, and testing is required. One must be sure to plan for all potential pump and siphon failures when determining the levels in the sump and the main tank. Is a sump necessary? Not at all. In fact, I don’t use a sump on my 55-gallon reef tank. I have no room, and since I live in an apartment, it’s not the best idea for me – too great a chance of disaster for my liking. Many folks love using a sump, though and from what I’ve read on the various internet bulletin boards, most folks do use one. If you plan properly and once the kinks are worked out, sumps really do seem convenient. Q: I’ve heard peoples tanks have drained into their sump during power loss, how do I prevent this? A: Well, lots of bad things can happen in a power outage. I, like you, have heard of people’s tanks overflowing after a temporary loss of power. I do not use a sump myself but here are a few tips I have collected from people who do. The most common mistake is probably lack of planning. There are a great number of technically minded BRS members, along with a wealth of information available on the web regarding tank capacities and how to calculate how much water will continue to flow during a power outage or loss of siphon for those using external overflows. It is important to calculate how much water will drain from your main tank to your sump when the pumps fail. Obviously enough space should be left in your sump to accommodate this water. Similarly you should calculate how much water would continue to flow into your Volume 1 Issue 4 Calendar of Events June 28th BOSTON REEFERS JUNE MEETING : MACNA 2004 RALLY WAKEFIELD LIBRARY July Potential Joint Meeting of BRS/CARS/Upstate August 23rd BRS August Meeting Guest Speaker Sanjay Joshi Sept. 5-7 MACNA XV Louisville, KY BOSTON REEFERS to host MACNA XVI Thanks to the efforts of Marvin Parramore with help from Ron Wishna, the BRS Officers and Board of Directors, the Boston Reefers Society will be the proud hosts of MACNA XVI next September. Marvin, Ron, the Officers and the Board along with a number of eager volunteers have already begun making preparations for the event. The Hyatt Harborside Hotel has already been secured as the venue and a significant number of speakers have already given us an unofficial nod expressing their interest. Even though the MACNA Committee members have already started their work, we will need everyone’s help to make this MACNA an event to remember. Sign-up sheets have already started circulating for the various committees. If you haven’t had a chance to hear about our plans or aren’t sure what committee you’d like to work with, contact Marvin (tstone) or Ron (mantishunter) on Reef Central or drop an email to the BRS officers at [email protected]. Page 1 THE NETTING MATERIAL FUND LFS Q&A The Boston Reefers Society is a strong supporter of responsible, ethical, environmentally conscious specimen collection methods. At last months meeting we collected donations for the Netting Material Fund which promotes net caught fish as opposed to other less desirable methods. The BRS’ donation along with funds from a great many others has allowed the Netting Material Fund to exceed it’s goal of $3,000 to provide nets for Philippine collectors. Exceeding this goal has prompted expansion of the project to buy nets and train collectors in Indonesia. Donations are still being accepted so please visit www.reefsource.com/netting_material_fund.htm Information about the Netting Fund (edited and reprinted with permission of course) Marine Specialties International, Inc. is pleased to be working in conjunction with Ferdinand Cruz and Reef Central to provide a way for hobbyists and retail store owners to be directly involved in getting netting material to collectors in the Philippines and Indonesia. WHY ARE NETS NEEDED?: Many collectors in the Philippines are eager to stop using cyanide and start using nets to catch the fish for this industry. However, the collectors are not rich people, and they are unable to purchase the material themselves. Most export companies and non-profit organizations have provided little if any netting to the collectors. Trainings are taking place, and many collectors are being converted. But what good is training if there are no nets Training In the Phillipines Volume 1, Issue 4 to leave with the collectors? If we want to stop cyanide fishing, we have to stop talking about it and start doing something. That is what this fund is all about. WHAT WILL THE MONEY BE USED FOR?: All monies collected will go towards purchasing the netting material, paying for shipping to Los Angeles and then on to the Philippines or Indonesia, and paying for any sales/export/import taxes, custom charges, etc.. involved. Our first goal is to raise $3000 to cover all expenses for shipping 15 100-meter bundles of netting to the Philippines. As I have not shipped such items overseas before, this is an estimate. If we go over the goal, the additional money will be used to fund the same project for Indonesia. WHERE WILL THE NETTING GO?: The netting material will be shipped to Ferdinand Cruz. This is one of the few people that I sincerely trust in this industry. He has devoted his life to net trainings and is in the field everyday. He formerly conducted the trainings for the International Marinelife Alliance and the Marine Aquarium Council until his resignation late last year. I know that he will get the netting to the people who need and deserve it the most. More info about Ferdinand and his dedication to responsible specimen collection can be found at the netting Material Fund website. WHY ISN'T THE MONEY GOING TO A NON-PROFIT ORGANIZATION?: Netting material is cheap. Dirt cheap. Some of the organizations "dealing" with cyanide use receive millions of dollars in grants. One would think that the Philippines would be so inundated by netting material that they wouldn't know what to do with it all!! However, that is not the case. The shortage of material is truly disgusting. It is the most important tangible item to create change, yet no one seems to want to spend a few thousand dollars to provide it. As soon as I found out how cheap the netting was, I got extremely angry thinking about all the money that has been spent by organizations and the collectors still don't have what they need. By handling the situation myself I know exactly where the money is going and that it is being used solely for its intended purpose. by Steve Shannon This month we asked six Local Fish Stores (LFS) : At what salinity level do you keep your livestock?

Two types of netting were purchased- a 1/4" mesh and a 1/6" mesh. We will be sending over 2.5 miles of netting that is 7 feet wide!!! This will then be cut into hand nets to supply hundreds of hand nets to collectors in both the Philippines and Indonesia. tank if the overflows failed but the pumps continued pumping. Another common mistake is failure to account for all of your system components, not just the tank and the sump. Skimmers, reactors and the like can hold significant amounts of water. Moe’s Hydnophora – gift of Joe Venuti Moe’s Pink-tipped Acropora from Greg The final mistake would be not realizing that when most return pumps fail, a siphon will be created in the reverse direction and the water will flow out of your tank into the sump until the end of the hose sucks in air and the siphon breaks. Check valves or anti-siphon valves can be used but a few strategically placed holes in the return line just under the water will do the trick just fine. The most important thing you can do though is, once you have set the system up according to your calculations, TEST IT! Better to test the possible failures while you are there than to have them tested for you when you’re not. Having an experienced hobbyist take a look at your system is also a wise plan. It is likely that newbies can learn from veterans’ mistakes. Q: Do I need a Refugium? What is a refugium? A: A refugium is typically another (yes another) smallish tank added to the plumbing system. The refugium is generally lit by an inexpensive system – just something sufficient to support algae growth. The basic idea is to have a small tank growing macro-algae grow where the fish in the reef tank cannot get to eat it. Macroalgae is just a fancy way of saying “big algae” an example would be the species Caulerpa. The macro-algae soaks up nutrients (like phosphate and nitrate) to help keep those levels as close to zero as possible. Volume 1, Issue 4 There are numerous species of macroalgae currently used in the reef hobby. Some of the more popular ones are Caulerpa, Grassilaria, and Chaetomorpha. Caulerpa seems to be the most prevalent species in widespread circulation however, recently we learned from Anthony Calfo that there are better choices of algae to use. Caulerpa has a nasty habit of spawning in unsuspecting hobbyists’ tanks. The upshot is fish and corals can’t take the nutrient spike and may suffer. Even without spawning (or “going sexual” as often described) Caulerpa presents some problems. It may turn the water a bit greenish, and it is suggested that many of the substances that Caulerpa constantly leaches may be designed to inhibit coral growth. Anthony offered some better alternatives, notably Chaetomorpha and Grassilaria. Many hobbyists here in the Boston area are already growing and harvesting these two macro-algae and it is common for folks to give the stuff away at our meetings. Chaetomorpha and Grassilaria don’t require too much in the way of lights – most people keep them under normal output fluorescent bulbs. Macro-algae are low maintenance. Just drop it in the refugium, provide it light, and watch it grow. In addition to macroalgae, some people will place small shrimp and other invertebrates in the refugium. These creatures, which are of great benefit to overall system health and water quality, may get eaten in the show tank, but a refugium can act as an isolation ward where they can grow and prosper. Of course an occasional invert or one of their offspring may get sucked into the return pump and sent into the show tank. That’s just fine, as the moment provides good fresh food for your fish.

Page 3 A Tale of Two Drippers by Rob Tess & Ron Wishna Thanks to a group purchase of Calcium Oxide powder, Ron Wishna (mantishunter) and I (RobboT) recently joined the ranks of those who drip kalkwasser. Not having the space required for barrels of RO/DI with auto top-off devices, float switches, and Nielsen Reactors; we each came up with our own D.I.Y. Kalkwasser drippers and thought it might be of interest to the rest of the BRS. the always familiar gurgle of air being drawn into the bottle provides periodic mixing of the kalkwasser solution. Although this does re-suspend some solids there is no negative impact to the tank since addition occurs in the sump.

For more info on LMAS or MACNA XV visit: www.lmas.org or www.masna.org MASNA Auctions! The Spigot of Ron’s Dripper For those of you who don’t already know, MASNA has an auction site. The site was primarily established to assist with MASNA fundraising efforts. However the folks at MASNA “hope it will eventually become a central marketplace for hobbyists and vendors alike to list the items they're looking for or possibly putting up for auction some of those items in the closet you no longer have use for.” Please check it out at : www.masna.org/cgi-bin/auction/auction.cgi Ron’s Dripper Ron’s Dripper The drinking water spigot is attached to a length of 1/4-inch tubing which runs under the tank stand. There it is reduced to 1/8-inch and goes into a small pump which provides consistent flow. Ron’s dripper as the pictures show was a great adaptation of household furniture to reef-keeping equipment. Since Ron’s 75g tank is in his living room and since the area under his tank is occupied by a sump, it was necessary to develop a system that could stand out in plain view. Using a common bottled water dispenser Ron made a dripper that was both functional and relatively unobtrusive. In Ron’s system Kalkwasser is mixed in 5gallon batches in a standard water bottle and placed into the dispenser as one would normally do for drinking water. Due to the fact that the spigot is slightly elevated above the bottom of the dispenser base, there is very little solids carry-over to the sump once the kalkwasser mixture settles down. As kalkwasser is drawn out of the water bottle Volume 1, Issue 4 MASNA invites everyone with an interest in the marine aquarium hobby to participate. It's Free!

My dripper is far less attractive but given it’s location this is perfectly acceptable to those in my family who would normally be concerned about such things. This design comes from a number of similar drippers I have seen at websites. The mixing container is a 5-gallon Kerosene container like you would find at most hardware stores (I got mine at Home Depot). Two holes were drilled in the container: one in the side about 2 inches from the bottom, and one in the top. The diameter of the holes is slightly smaller than the outer Kalkwasser is mixed by adding the powder to the container through the cap in the top, filling with water, and swirling the mixture around. The dripper valve is closed for about 1-hour while this happens, then I purge the line to make sure no solids are present that could clog the valve. Getting Started (continued) One last point about refugiums: they can also assist in adding pH stability to a reef tank. With the refugium light cycle timed opposite to that of the show tank the result of the photosynthesis in the refugium will help to abate the dip in pH that you may see in the show tank after the lights go out. That’s another nice feature of refugiums. In short, I highly recommend them. Q: What is a Reef Ready tank? A: A “Reef Ready” tank is one that has built-in overflows. Now that will take some explaining. I explained above what a sump is, and why folks use them. To make Dripper Lines in Rob’s Sump So there you have it. Two different tanks; two different DIY Kalkwasser Drippers. In both cases it is important to note that the container is a sturdy one. This is necessary since as the kalk leaves the container a slight vacuum is created. If a sturdy container isn't used, the container will collapse. In the case of Rob’s dripper this defeats the purpose of the fail-safe mechanism. As always, feel free to get a hold of either Ron or Rob to ask any questions. Rob’s Dripper diameter of standard airline tubing. This ensures a snug fit. Airline tubing passes through each of the holes and is sealed using aquarium silicone. The tubing that comes from the top of the container is a fail-safe mechanism. The end of this tube is placed in the sump at a level somewhat below the top of the sump container. If the water level should reach this tube no air will be able to reach the kalkwasser container thus stopping the flow of kalkwasser to the sump. The tube that comes from the side of the container is runs to the sump and is the dripping line. Flow is regulated using an airline valve. The flow rate is adjusted to mimic the evaporation rate of water from Volume 1, Issue 4 Neatly Tucked Away Out of Sight Moe’s Assorted Mushrooms – from Flying Fish Express plumbing a sump easy, some tanks come with holes already drilled in the bottom, and with a bulkhead built in. All one needs do is hook up piping from the bulkhead to the sump, the pump, and then hook the return line back to the show tank. To prevent all the water from going right down the pre-drilled hole, Reef-Ready tanks have a wall built which sections off the drain. No water can get around this wall. The water is forced to go over the wall. That way, one can select the height of the tank’s water by modifying the height of the wall, right? If one keeps the height of the wall lower than the height of the tank, then before the tank can overflow, all the excess water will go over the wall and down the bulkhead. As an added benefit, this built in overflow will skim off the surface of the tank water. Down the drain it goes into the cleaning apparatus below. Then the pump returns nice clean water. “Reef-Ready” tanks cost a bit more money, but if you can afford it, go for it! Next month more of Dave Balch’s questions and my answers. Happy Reefing. Page 5 Tank of the Month I started this tank almost 4 years ago. I had had fresh water tanks when my children were young but had always wanted a saltwater tank. I knew that it would cost more money and time than I had back then, but it was always in the back of my mind. When the opportunity came up to start one, I read a few Paula Obuchon (Sea Serpent) books and went to a LFS and bought the whole shebang. Of course, it was all the wrong stuff! Since that original setup, with the exception of the tank and stand, there is NOT ONE original fitting or piece of equipment. The best thing that the LFS recommended was a good RO/DI setup!
