The Tetra HT 50 Electronic Aquarium Heater is a fully submersible electronic heater designed to maintain a stable, adjustable water temperature for tropical aquariums. With 50W of heating power, it is recommended for aquariums with a capacity of approximately 25–60 litres. Its electronic thermostat allows precise temperature adjustment from 20°C to 32°C, helping create suitable conditions for tropical ornamental fish.
The integrated microprocessor supports reliable temperature control, while the three-stage LED indicator makes it easy to monitor the heater's operating status. The thick, heat- and shock-resistant borosilicate glass tube, protective plastic cap, and additional safety shut-off function provide added protection during operation. Two suction cups help secure the heater inside the aquarium, and the 1.6-metre power cable offers flexible positioning.
**Directions for Use:** Set the desired temperature using the control at the top of the heater. Secure it inside the aquarium near the filter or another area with good water circulation. Ensure the water level remains at or above the minimum water-level mark before connecting the heater to power. After unplugging, allow the heater to cool for at least 15 minutes before removing it or lowering the water level below the minimum mark.
