DO NOT buy unless you want to lose the whole tank! I bought this heater to use. Instead I kept it as a backup. I've only used it new out of the box a few times to heat water for a change. I was heating 5 gallons of salt water when I noticed a flickering lamp in my dining room. I turned it off Then I started smelling a strong odor of burnt plastic. The Aqueon heater shorted out and melted in my 5 gallon container that I was about to use for a water change. Luckily no one was injured and no property was damaged apart from the heater and container. I'm so glad it wasn't in my aquarium! Do not buy!
