Hey Well I Am new here. Thats a duh statement. I am just getting into saltwater. I am starting with a small 55 g tank. I want to learn the ins and outs before I go to the real tank wich I will be building into my wall. The size is yet tobe figured out for sure as it will be in the corner where the fireplace once was. Aprox 48"X47"X42". I already found out how NOT to wire a light. I have had my tank running for five days and to look at it drives me nuts!!! Nothing but a tank of water. But I wanty to do it right so I will wait to ad any live fish or soft corals until the tank matures. Talk to yall later. P.S. I am also the type that if it aint perfect then redo it till it is.
