I've been using the eheim aquarium heater for a few years now, I bought this for a small pond which after two weeks of heating is set to 68 degrees Fahrenheit I can use the Not holding temperature, it's 300 watts that can handle a 100 gallon tank. My pond is only 65 gallons and the heater is on minimum. I called eheim but didn't answer so I did a calibration to make sure it was working again a few days and yesterday 17/06/21 the heating stopped working. I tried calling Amazon but was given no option so I'm stuck with a broken heater, if you are buying an Eheim heater please do not buy from this seller.
