Tetra's Submersible line of heaters are easy-to-use and work in aquariums ranging from 2 to 55 gallons.

The heaters have electronic thermostats that automatically adjust heat output to keep water at a constant 78 degrees F/25.5 C. All submersible heaters have indicator lights to let you know when the heater is on, heating the aquarium.

The low voltage thermostat maintains water at 78°F without any adjustment required. Be sure to purchase the correct heater for your tank size.

Buying a heater too small for your tank can cause under heating. It is critical to ensure your tank is equipped with a hood or glass canopy to contain the heat inside the aquarium.

All Tetra submersible Heaters will shut off if an electrical short is detected for your safety.
