ok. im gonna try to list everything. but like i said before, since i didnt purchase everything myself, some of it i dont exactly know what im looking at. first off, it is a 100 gal tank, 55 lbs of live sand (3 inch sand bed) about 80 lbs of live rock with purple coraline algea and some red and green mushrooms. there is a briny starfish and a sand sifter star in there, lots of hermits and snails. 2 true perculla clowns who are about 2 1/2 inches long a piece. 1 maroon clown who is about 3 1/2 inches and a foxface who is the same size as the maroon clown. there is a long tentacle anemone in there, but i will be taking him with me to work (i work at a pet store) until the tank is more under my control and i dont want to kill him. as far as equipment goes, the light says current on it, it stretches the length of the tank and has 4 bulbs, 2 blue 2 white with a reflective background and a fan to keep it cool. it doesnt say the wattage on it so im not sure, but my boss said it is a light built for a reef tank. it has one canister filter that says the brand is a grech gw-302, voltage 120v/60hz, power 18w, h-mar 1.4m, q-max 1000l/h, 2 power heads, a uv sterilizer with no name on unit but it is pretty large and attached to a marineland magnum 350 convertible canister filter that also has 2 marineland biowheels attached on top of tank. rena cal heater 300w. tank is at 78.7 degrees presently. and a asm protein skimmer g-1x. salinity is at 1.025. ammonia is 0. calcium is at 400ppm, ph 8.2. i have been doing about a 20% water change every week sometimes a little more depending on how dirty it is.
