| how it started |
|
I kept freshwater tanks as a kid, and always wanted to try a saltwater fish tank. When I decided to set up a saltwater tank, and began reading about it, I discovered that people were sucessfully keeping reef tanks. All it took was one visit to the LFS to see some corals, and I was hooked. |
|
| the secret |
|
This isn't rocket science. It's all about nutrient balance. You need to *FEED* as much as possible without fouling the tank. Well fed livestock is very hardy. The fact is we can't feed the livestock the amount of food they get in the wild without creating an algea plantation. But we can do a few things to help the balance.
1) Low Bioload - You have to decide before hand if you want a fish tank or a reef tank. Don't try to both in the same tank. The more fish you have have, the harder it will be to properly balance the nutrient equation. Add too many fish and you will most likely have either an algea problem or end up starving everything in order to keep the algea at bay. Notice that I have only 5 fish in a 125 gallon tank.
2) Export as much nitrates and phosphates as possible (including crud before it breaks down). This means a very good skimmer *constantly cleaned and tuned*. Do frequent water changes with proper syphoning. Provide good water flow (don't forget blasting the rock on a regular basis with the turkey baster). A fuge with macro can help (unfortunately I don't have room). If you can't run a fuge, consider chemical media to remove the phosphate (Phosban, Rowa etc.).
3) Constantly adjust feeding - Don't get stuck on the same exact feeding schedule. If you see no signs of algea, try increasing feedings. Don't increase the amount you feed at one time, but increase the *number* of feedings. Break it up throughout the day (I feed my daily food quota over three different feedings). If you start to see signs of excess algea growth, cut back feeding temporarily by a 1/3. Increase your export efforts. If it doesn't improve, cut back by another
1/3 for a few weeks. When it improves, increase the food back by a third. And so forth. Again, don't increase the amount of food in a single feeding, increase the number of feedings. In fact, try spliting the amount you currently feed into several smaller feedings. Also, I prefer to try matching what the organisms eat in the wild. As a result I feed a larger quanity of "low nutrition" foods (brine shrimp, krill, formula 2, etc.) rather than a small quantity of "high nutrition" foods (such as formula 1). And I never use additives such as vitamins and selcon (except maybe in a hospital tank treating sick fish). |

| Tank information |
| |
|
|
|
| Display Tank |
|
Lee-Mar 125 gal glass tank (72" x 18" x 22" ) |
|
| Sump |
|
DIY modified acrylic 30gal L (36" x 12" x 16") |
|
| Fuge |
|
No fuge. The middle compartment of my sump does have some LS and LR in it, but no macros. |
|
| Design |
|
The system was designed to minimize the possibility of floods and overflows. The sump consists of 3 compartments so that in case of plumbing failure, pump leak, etc, about 8 gallons of water would leak out on the floor (which worked as expected when my return pump blew a seal in January). A Dolphin Ampmaster 2100 return pump feeds three Sea Swirls. The sea swirls break the siphon well before the sump overflows when the pump is off. The corner overflow is covered w/ eggcrate to prevent livestock from entering the overflow and clogging the return pipe. |

|
| Live Rock |
|
About 200 lbs (50% Fiji, 25% Marshall, 25% Tonga) |
|
| Live Sand |
|
200-250 lbs. I started with about 3" of CaribSea Aragamax Select. I then added another 1" of LS obtained from 3 different vendors. Finally, I seeded the bed with an infauna kit from Indo-Pacific Sea Farms (I re-seed the bed yearly with an infauna kit). |
|
| Comment |
|
All of the LR was hand picked from curing bins at Aquatic Warehouse, Octapus Gardens, and Jeff's Exotic Fish in LA. Each of the vendors claimed that their LR was already fully cured, but I cured it an additional 2-3 weeks in bins in my garage (it never did show any ammonia, so it probably was cured). I then aquascaped it in my tank, and let if run with full lighting, flow etc.
for another 4 weeks before adding the sand. That way I could easily siphon off the debris that was shed. Never once did I have an algae outbreak. |

| history |
|
April (2006) was the two year mark. I haven't changed much since I started it. This past year, I've mainly watched the coral grow and fill in. I haven't added any corals or livestock other than some cerith snails over the last nine months. As for equipment, I added the Nilsen reactor , auto-top off, and automated two part dosing system for convienience. |

|
| filtration & Reactors |
| |
|
|
|
| method |
|
No real filtering except biological filtering of the LR and LS. When the particulate matter starts to build up (every 6-8 weeks) I will use a filter sock on the inflow to the sump. I rotate 3 socks for 3 days each (9 days total). Then I remove the socks for another 6-8 weeks. Just a DSB (4") system. |
|
| carbon |
|
I run 3 bags of carbon in the sump 24/7. The bags are changed out in a staggered fashion, so that one bag is replaced every 2-3 days. Currently, I'm using Kent Marine Reef Carbon. |
|
| CA Reactor |
|
Advanced Reef Technologies K2R Calcium Reactor controlled by an American Marine Pinpoint pH controller. Media consists of ARM, and effluent is maintained at a pH between 6.6 and 6.8. A second pH probe on my Neptune Aquacontroller II turns off the CO2 to the reactor when the tank pH drops below 8.0 (it is usually off ~6 hours during the night). |
|
| Nilsen Reactor |
|
MRC Nilsen reactor filled with 2 cups of Kent Marine Kalk. An Aqua Medic dosing pump, which is turned on by a float switch, pushes RO/DI top-off water through the Nilsen Reactor into the sump. The top-off water is stored in 10 gallon water barrels in order to prevent a massive flood from a top-off system failure. The Neptune Aquacontroller stirs the Kalk for 15 min. every 105 min. (while turning off the top-off pump during stirring). Also if the tank pH rises above 8.5, the Aquacontroller suspends additions of Kalk until the pH falls). |
|
| Phosban Reactor |
|
Two Little Fishes Phoshban reactor, running Phosban, which I replace every 3-4 weeks. The reactor is fed by a Mini-Jet 404 powerhead. |
|
| Dosing |
|
I also dose Kent Tech CB 2-part daily using an automated Nautilis 3A dosing pump from Reef Dosing Pumps. 20ml of each part is added at 7am and another 20ml at 11pm. The peristalic dosing pump doses this amount over a 20 min. period. |
|
| skimmer |
|
Euroreef CS8-2 skimming wet. It has been modified to include a wooden airstone powered by a TetraTec Deep Water air pump (the additional micro bubbles from the air stone increase the skimmer's efficiency by about 50%). I empty the full skimmer cup every 2-3 days. Every time I empty the cup, I also clean it thouroughly to maintain the skimmer efficiency. |

| comment |
|
I don't stir (the substrate), but I will ocassionally siphon off large particles, debris and other junk on the very top of the sand bed. I have around 30 Nassarius Vibex snails living in the sand bed which keep it stirred up.
The three most important tools in maintanice are the turkey baster, soft bristle toothbrush, and a small diameter (3/8") rigid siphon tube. I blast the rocks nightly about 30 min. after lights are out. Not only does this keep crud from accumulating in rocks, but it also provides a food source for the corals (which are well into their natural feeding cycle 30 min. after lights out). Water changes are not just for changing out water, but is an excellent
form of export if done correctly. When I do a water change, I'm cleaning and and syphoning out as much crud as possible, so when I'm done, I have a tub of the foulest possible water. I start by blasting the rocks with the turkey baster. Your syphon tube should be small enough (~3/8") so that you can finish syphoning the crud before removing enough water for your water change. On the end of my syphon tubing I attach about an 8" to 12" piece of rigid plastic tubing. The tip of the rigid tubing is cut at a 45 deg. angle making a nice point. Thisallows you to scrape off algea and other crud from rocks and other hard to reach places. If a problem area of algea does start to sprout up, I hit it with the toothbrush during water changes. It usually only takes one or two cleaning sessions and the algea stops appearing in the spot. |
