I was just wondering at night when i turn the lights out on my desert set ups the humidity like jumps up almost to 70 and thats bad so i need to figure out how i can lower it. i tride moving the tanks around but it dosent do too much really, and i keep the room temp down as well so its not that, so if anyone can help me that would be great. thank you

I think i mentioned this in another thread. My friend uses a personal fan to help circulate air when he turns off his light over his A. A. tank. Says it helps the tank from getting condensation, thus keeping the humidity low.
