What does everyone do in the summer to keep their tank heat down. I do not have the more or the place for a Chiller. I was curious what other people do in order to keep their tanks 78-80 on a 85+ day in the summer. My tank is in my room and i usually keep an AC in there in the summer but this is the first year i have a tank. My regular lights would usually dim from the AC kicking on an off. Would this be a problem for my MH lights on my tank?
