Smart heating you can rely on

With a tightly wound nickel-chromium heating element, the heater distributes warmth evenly, helping maintain stable water temperatures as fish and plants settle in. The real-time temperature sensor continuously reads the water and adjusts the set point to your chosen value, reducing dramatic fluctuations. If the water reaches about 95°F, the unit will automatically cut power and display an EE code to alert you.

Safe, external control

The external controller with LED digital display keeps electronics out of the water, reducing risk and making adjustments convenient. You can set the target temperature from 65°F to 93°F, with 1°F increments. The real-time readout lets you monitor temperature at a glance.
