Tronic Electronic Heater 150w A762

These completely submersible heaters have fast heat technology, which means that the Tronic heater stays on until the aquarium is at the desired temperature. Most other heaters cycle on and off. Tronic heaters have a patented Thermo-Sensor that makes the heaters water sensor as accurate as a separate probe. Other features include: safety shut off and solid state design that allows the heater to be positioned at any angle. The Tronic heater is the most advanced heating technology available for your aquarium. Includes two suction cups for easy mounting. Use of the Tronic Heater Guard (not included) with your Tronic Heater will help protect your heater from damage and your fish from coming in contact with the heater when it is operating.
