Enjoy the convenience of Tetra's HT heaters that make heating your tank simple. Suitable for aquariums from 2-55 gallons, these heaters feature electronic thermostats & indicator lights that let you know when they're in use. The thermostat automatically maintains a constant 78°F, while an integrated safety system will shut off if an electrical short is detected. Choose the correct size for your aquarium: HT10 (50 watt) - 2-10 gal, HT30 (100 watt) - 10-30 gal, HT40 (150 watt) - 30-40 gal & HT55 (200 watt) - 40-55 gal. Don't forget to install a hood or canopy to contain the heat!
