So far I have taken of the lids of the aquarium, and there is one fan blowing on the MH
that are hanging 12 inches above the aquarium. I have just bought another 2 fans on ebay, and what I think I will do is blow one across the other side of the lights, and blow one across the surface of the water that is being rippled by a powerhead and the return. I will also move the MH
balast from inside the stand and put it to the side. We will see how all that works. That should get it to acceptable levels, but, I still think I will eventually need a chiller, because my tank is in the basement, and the way my HVAC is designed, it is actually warmer in my basement in the winter. So can you guys give me some tips as to which chillers you prefer?
