[Son Of Skyline]

Thanks for the info everyone. I do have a fan over my tank, but I've noticed that on a few days this spring my tank has shot up from 82 to 84 degrees. My tank normally holds even at 82 night and day. I guess I'll just have to have another fan ready for those potential hot days. I am concerned about evaporation though, as even now I can get as much as 1.5 to 2 gallons of evaporation per day in my 27gal tank.
