I live pretty much in the middle of the desert and it is getting HOT here. We're not even close to midsummer, either, so it'll only get worse. Do you guys have any ideas for cooling a 10 and a 2.5 gallon tank? I have a few water bottles in my freezer, but isn't that too much for a 2.5? Too much for a 10? The heater for the 2.5 is wacky, too, so I don't know if it can keep my tank steady with a water bottle in there. Help?
