I'm in the market for a chiller for my 72 gallon bow front mixed reef tank. I probably have about 100 gallons between the tank and sump. My apartment gets ridiculously hot in the summer. The A/C bills last summer almost put me in the poor house. I want to keep the tank at a nice 77 or 78 degrees all the time. My tank is in the living room, so it needs to be quiet, and if possible, ENERGY EFFICIENT!!! Any suggestions? Thank you.
