Tetra 50W Submersible Aquarium Heater for 2-10 Gallon

The Tetra® HT Submersible Heater is expertly crafted to ensure your aquatic fish enjoy a comfortable environment. With its electronic thermostat, this heater automatically regulates the water temperature to a consistent 78 degrees Fahrenheit, effectively preventing overheating and thereby extending the longevity of the heater. Equipped with a dual-indicator light system, the heater provides visual cues: a red light indicates that the water is actively heating, while a green light signifies that the desired temperature has been reached.

Inside the heater, silicon carbide crystals enhance both heat distribution and transfer, creating an evenly warmed environment for your fish. Constructed from robust glass, the heater is designed to resist both heat and shock, ensuring durability. Installation is straightforward, as you simply attach the heater to the interior aquarium wall using the included suction cup. It is best positioned in an area that benefits from good water circulation.

The 100-watt HT30 is suited for tanks ranging from 10 to 30 gallons, while the 150-watt HT40 caters to 30 to 40-gallon aquariums. For larger setups of 40 to 55 gallons, the 200-watt HT55 is the right choice. All models have received UL Listing, assuring users of their safety standards.
