Smaller tanks overheating in summer?
Hello,
I run a 20 gallon, along with 300W of lighting in an enclosed hood (completely enclosed for the sides and top), used to have also the Dolphin 1200 SST pump running, etc. In the summer, the tank will heat up very hot if no cooling is done. So I put a fan in the hood blowing air directly on the water surface and it works fine. I must add that my sump is open so water can cool down there as well.
