OASE Indoor Aquatics HeatUp 400 Adjustable Fish Heater

The OASE Indoor Aquatics HeatUp 400 Adjustable Fish Heater makes it easy to keep your aquarium at the perfect temperature. You can adjust the temperature scale from 66 to 90 degrees Fahrenheit, and a secondary knob control allows for precise temperature adjustment within two degrees. Bi-metal technology automatically monitors and controls temperature levels, and a thermal shutoff switch adds extra protection. An activated control light lets you easily see when the unit is heating. The heater is energy efficient, too, to help keep your electricity usage down. The included holder and suction cups make it easy to install the heater on the side of your fresh or marine water aquarium.
