The tank has been set up since 1-27-2007. I had a small 20 gallon reef tank about 8 years ago in which I kept mostly soft corals and I used a "high-tech" Fluval canister filter as a filtration system and my prized coral at that time was the xenia. Boy...how times have changed. I then quit reefing for many years because of my study. The addiction slowly creeped up again last year and I spent a lot of time reading and catching up on the "what's new" in reefing. I mananged to convince my wife to set up a reef tank in our office since it would make "our" office look nicer, can use it as a tax write-off, and bring good luck in a feng shui sense. She agreed and the rest is history.

Tank
I bought the tank from PetCo. It came with the stand and canopy. The dimension of the AGA reef-ready 90 gallon tank is 48" (L) X 18" (W) X 24" (H). It has one internal overflow which I plumbed using the Herbie method for silence.

Lighting
Two DE 14K Phoenix 250 watts on IceCap ballasts supplemented with two HO 48" 54 watts T5 on individual SLR reflectors. One bulb is Giesemann AquaBlue + and the other is ATI Actinic Blue. Lighting schedule is 10 am-5 pm MH and 9 am-7 pm T5's

Circulation
Return Eheim 1262 Pump and two Tunze Turbelle NanoStream Pump 6045.

Filtration
The system has a very simple set up. The sump only has 3 compartments in which one of the compartment is used for cheato placement and another that uses a filter sock to catch debris from the draining pipe. I don't use a skimmer, calcium reactor, chiller, or any type of controllers. The only digital displays that I have are the pH probe/monitor and a digital thermometer.

Maintenance
Maintenance: I have to admit that I do a lousy job of maintenance. The tank was set up at the end of January '07 and I did not do any water changes until last week. What prompted me to do this is that I could not get the Alkalinity high enough and I was starting to see some ill effects to my acropora. I do use B-Ionic but I don't think this is enough. The water change did improve the condition of the corals. I don't have an auto top off so I replace evaporated water by hand with RO/DI every day. During the hot summer months, I put in 2 big ice cubes that I freeze using tupperware containers as a mean of cooling the tank as well as replacing evaporated water. During the hot summer months, my tank's temp reaches up to 84.7 degrees everyday. I have really pushed the envelop but there is one thing that I think matters most (even more important than lighting, flow, temperature) is good chemistry of the water and therefore water changes is so important. If you plan to cut corners, try to avoid the not doing water changes..
