The Hygger 300W Aquarium Heater with Digital Display provides adjustable heating for freshwater and marine aquariums from 94–300 litres. Its external digital controller displays the current temperature and allows adjustment between 15–34°C without reaching into the water.

Key Features

  • 300W heating capacity suits aquariums from 94–300 litres.

  • External digital controller makes temperature checks and adjustments convenient.

  • Adjustable 15–34°C range accommodates different aquarium requirements.

  • Overheating and dry-run protection automatically switch off the heater.

  • Heat-resistant guard helps prevent fish from contacting the heating element.

  • Memory function restores settings after a power interruption.

Product Description

Maintain suitable water temperatures with the Hygger 300W digital aquarium heater. Designed for freshwater and marine setups, it combines a quartz heating tube with an external controller for straightforward monitoring and adjustment.

The quartz tube distributes heat evenly, while the protective guard creates a barrier between fish and the heating element. Built-in overheating and dry-run protection provide automatic shut-off for added reassurance during everyday use.

Select a temperature between 15–34°C to suit your aquarium’s inhabitants and view the current reading on the digital display. The memory function restores your settings following a power interruption, and the supplied suction cups help secure the heater in position. This model includes a two-year manufacturer’s guarantee.
