bringing temperature down
Hello, I am having trouble keeping the temperature in my tank down. I am concerned because it is heavily stocked with fish. I also have been reading that plants do best at less than 80 degrees. Im keeping java fern, anubias, saggitaria, crypts, moss balls, and anacharis. My tank is holding steady at 84, its a 180 gallon and I have to keep the tank covered because of evaporation problems I was having, or else I would just run a fan over it. I keep my home at a consistent 75 degrees so its not my ambient temperature thats causing the problem, I assume its my power compacts. Im running four 96 watt bulbs over the tank, and Im sure its generating quite a bit of heat. I know I can just buy a chiller, but I really dont want to if I dont have to, they are not cheap, especially ones made for tanks this large. Does anybody have any ideas on a more cost effective way of reducing the temperature in my tank. Any help is greatly appreciated.
