Okay, I have two tanks in my room, one 55 gal freshwater and one 30 gal saltwater. And there must be somekind of atmospheric phenomana going on, as my room is the coldes in the house, but the water temps in both tanks is too high, and nothing at all is working!! I normally like to keep both tanks at 75 degrees, but the freshwater is at 80 degrees and the saltwater is at 79 degrees. I've turned off both lights, both heaters, I've even dumped ice into the freshwater, but the temp hasn't lowered not even one degree!!! !!!! I don't know what to do, as the high temp in the freshwater has already killed one of my fish, and I don't want to lose any more!!!!
