Khoivo, i don't have an air exchanger, but i do have a huge attic fan that i haven't had to use yet. Attic fan vents air from top of the stairs at house center out through the attic, just no heat exchange. I'm going to monitor closely and then maybe have to make adjustments. I have 3 hygrometers in various points. So far I'm running both tanks and the 125gl is fan cooled with a full canopy puts out quite a bit of moisture. Once i switch over I'll only have the 480gl but will be running my lights much harder than i am right now. However, i don't plan on using any fans on the 480gl's water, all cooling done in fish room.
