I bought 3 of these for 3 identical grow tanks and installed them the same way. It was a bit like Goldilocks - one was too hot, one was too cold and the third was just right. The one that was too hot got so hot it killed the fish and evaporated 3/4 gallon of water from my 2.5 gallon tank in 16 hours!
