This is my reef tank, almost 8 months in. It will be 8 months at the beginning of March. I use well water, no RO/DI. About, 10 to 15 gallon water change, weekly. 1 unit bio-chem zorb, GFO, Carbon, 2 units Chemi-pure elite, and a filter pad in a canister, with 9Watt UV sterilizer on it, using a spray bar. 2 Maxi-jet, and 2 penguin powerheads directed at the front glass from the sides, and straight across the back, behind the rockwork. 2 Odyssea, 75 gallon, HOB skimmers. (1)4bulb T5HO 48" Light, and (1)2bulb T5HO light over the top 12 hours on, 12 off, with moonlights on, alternately. Glass lids, not topless. 1 HOB Odyssea refugium, with Chaeto., and two twisty daylights over that(bedside lamps, with CFL 6500K Bulbs). About 125lbs. of live rock(definately more, although I don't know how much.) Mainly Softy, some LPS, Zoas, and a small anemone(Bought as unknown polyp, and turned into 3 small anemones. Go figure.) I bought most of the corals from Garf.org, which is where the Aiptasia came in, so most are tank raised. Got an awesome deal, over Christmas, on a frag pack, from them. I forget the heater type. I dose 4tsps. of Kent CB Part A. and 4tsps. of Part B, every day. Salinity is 1.025. My params. are Ph 8.2, Ammonia 0, Nitrite 0, Calcium 360ppm, Alkalinity 10, (need to test Phosphate, and Nitrate, but last I checked both were 0, which I suspect to be wrong.) I skim wet. Inhabitants: 1 Yellow Tang(Tank Raised), 2 Ocelleris Clowns(Captive Bred), 1 Sixline Wrasse, 1 Cleaner Goby(Captive Bred), 3 PJ Cardinals, 1 Bangaai Cardinal, 1 Lawnmower Blenny, 1 Yellow Watchman Goby, 1 Reg.
