I can't get mine below 81. It usually stays around 82.5
Is this too hot
I live in FL. I have been on the lookout for some small hang-on fans, but it is January and they are not in the stores yet.
Thanks, Steve
Anyone with this problem, make sure it isn't being caused by a bad heater! I accepted that my lighting was causing my tank to stay above 80, then it kept creeping up and up over the last 2 years.. I tested and found out that TWO of my 3 heaters were defective. One wasn't working at all, the other was always on, no matter what you set it to. Thankfully I went with 3 SMALL heaters, else the bad one would have boiled by little fishes
Removed the 2 bad heaters, now my tank's keeping at 78, which is slightly above room temperature. Gotta replace the other heaters before winter comes so I don't burn out the good one...
