So I got an 100 W heater that was reccomended to me in the pet store, and says it is good for tanks up to 40 gallons. So anyway I have a 20 gallon tank and I put it at 77 degrees, and in the morning I checked on it and the temperature was all the way up to 82. I turned it down to 70, and waited another day, but the temperature wont change from 82. Any suggestions?
