My house only went up to 83 yesterday, tank was at 83.2, still no fan. Turned A/C on when I got home at about 6:30p
Not a bad temp without a fan or A/C!! 125g tank upstairs, 75g fuge/frag & a 40g sump in the basement. It's only 70 in the basement, so it acts as a passive chiller. When I have the new garage floor poured I'm looking into burying some tubing/flex pipe in the concrete to act as a chiller
