This summer will be my first summer to have fish and I know to keep a spare heater for winter which is what got me to thinking about summer heat. If you don't have air conditioning and there is an extreme hot spell, how do you keep your water temps controlled and not let them get to high? It gets quite hot and humid where I am for days and nights on end. This has to effect the tank temps I am sure. How do you handle this?

Oops..I thought this would be in the beginnners questions forum...............can't figure out how to move it.......sorry
