I actually pulled this thermometer out of the 72 gallon where it reads about 1 degree high, according to the Apex lite thermometer. The lowest I have seen the Biocube has been about 83.5 on the reading, so even if it's off, it's still at least 82 and change. It was 84.7 this morning before I turned the lights on.

Hi everyone, I'm new to this forum and new to the hobby. Long story short, I just bought one of the new version Coralife biocube 14g tank as a quarantine/child's room tank. I have the stock lighting and have a Koralia Nano in the corner opposite the return. I do not have a heater installed. The tank is away from any windows in a relatively cool area, actually right above a floor mounted AC vent. The problem is my tank is reading almost 85 degrees even with lights off overnight. Is there any real reason that this tank should run this hot? Is there anything I can do to cool it down, other than buying a chiller? I have a 72 gallon bowfront that is between 78-79 degrees and would like to get the Biocube to around the same temp, so I can transfer fish in and out safely.
