My tank is staying around 82-84 degrees without my heater. How is this possible? My room temperature never goes higher than 72-74 and I was forced to keep a fan on my tank to attempt cooling it. Since that, it doesnt reach 84 anymore but it still stays at 82. I thought it was my lighting but its not, it still stays hot without it on. its not next to a heater or source of heat of any kind, ive already thought of every external influence that may be possible. I am led to believe maybe its the abundance of microorganisms? What else could be possible that I am not thinking of? I find it really strange and Im about to totally run through the whole tank to try to "reset" it if you will.
