I live in Phx, AZ...the weather's starting to heat up here, problem is our tank seems to be heating up right along with it. New tank (a 55), new house, never encountered this issue before. Unplugged heater, tank is staying at about 82 right now, exactly the same temp as inside the house. We aren't ready to turn the air conditioner on yet, so aside from purchasing a chiller for the tank, does anyone know any cheap & easy ways to keep the tank a bit cooler? Kinda not fond of the idea of boiling our fish...
