I knew I'd get that question. It didn't matter. Temps were reading around 40F or 5C, and it DEFINITELY wasn't almost freezing in my tank, let alone in my room. I'd think I'd know if it were that cold.
Currently, tank temps are reading around 80 with the lights off on the Acurite, which is quite reasonable (I know this is a little chilly, this weekend I am getting another small UTH and a different light to fix this problem).
