Aqueon Preset Heater 50 watt

This is a 50 watt heater. Aqueon Preset Heaters are made with a durable thermal plastic shatterproof housing. This electronic thermostat is reasonably accurate (said to be +/- 1 degree) and is preset to a temperature of 78 F. Our experience is that it will commonly maintain a temperature between 76 and 78 F. The thermostat has an auto shut off safety feature.  LED heating indicator that illuminates when actively heating, letting you know when the heater is on. It comes with a limited one year warranty.  3.5" x 1.5" x 7" For aquariums up to 20 gallons.
