Tetra HT Submersible Aquarium Heater with Electronic Thermostat

The Tetra HT heaters are equipped with red/green indicator lights to inform you about the heater's status. The red light indicates that the heater is in the heating mode, while the green light signifies that the desired temperature has been reached and the heater is on standby. The low-voltage thermostat of these heaters maintains the water temperature at 78°F without requiring any manual adjustment. It is crucial to select the correct heater size for your tank to avoid under-heating. Additionally, ensure that your aquarium is fitted with a hood or glass canopy to contain the heat inside. For your safety, all Tetra HT heaters are designed to shut off automatically if an electrical short is detected.

The Tetra HT heaters feature indicator lights that clearly communicate the heater's operational status. When the heater is actively heating the water, the light will be red, and it will turn green once the desired temperature has been reached.

The HT20 model utilizes a built-in electronic thermostat that automatically maintains the water temperature at 78°F, which is the ideal setting for most tropical fish species. This feature eliminates the need for manual temperature adjustments.

These heaters are suitable for aquariums ranging from 10 to 30 gallons, provided that they are equipped with a hood or glass canopy to contain the heat. The compact design of the Tetra HT heaters allows for easy placement and concealment behind plants or other decorative elements within the aquarium.

It is essential to read all the label information carefully upon receiving the heater. Do not plug the heater into an electrical outlet until it has been properly installed inside the aquarium.
