I moved into a new home in the Chicago area recently and, lacking a fishroom, I decided to set up a 55G tank in the basement. I just had to have some fish!
Unfortunately, the basement in my new house is really cold, typically about 65F. I like to maintain my tanks at 76F, so that would mean keeping the tank 11F above the basement temperature. I knew I should insulate the tank to lower my energy costs.
