Who Gives A Fish Forums

Thanks for the suggestions! I'll check out the AC Infinity and the clip-on options. I do weekly water changes, about 20%, but I'll keep an eye on evaporation.

I've got a 20-gallon high tank that's running a bit warm lately, around 82°F. I'm thinking about adding a cooling fan but not sure what kind to get. Any recommendations? My room temp stays around 75°F, and I've got a lid on the tank.
