xReliable temperature control for freshwater and saltwater tanks
The hygger submersible aquarium heater is designed to maintain even, steady warmth across a range of tank sizes. With wattages from 300W to 1000W, you can pick the model that best fits your setup. Check Hygger's size chart for the right match; for example, 500W is commonly used for tanks roughly 66 to 135 gallons. The unit’s compact profile fits neatly under most lids, and a long power cord offers flexible placement options.

Smart safety features help you sustain a stable environment with less effort. The heater automatically cuts power if water temperature climbs too high or if the element isn’t fully submerged, and an alert signals when action is needed. This design aims to help prevent overheating and dry-running scenarios.

The digital LED controller lets you set a target temperature across a wide range and displays the current water temperature at a glance. The controller can be mounted on the tank edge with the included bracket, enabling adjustments without reaching into the water.
