This heater is 55 gallons. Aquarium. Temperature control was everywhere: every two minutes from 85 to 70 degrees and back. There were no fish in the tank so I left the heater on overnight hoping it would settle to the temperature I had set. It's not like this. It just kept breaking. If you are looking for a reliable heater, you should look elsewhere.
