Tetra HT Submersible Aquarium Heater, 50-Watt, 2-10 Gallon

The Tetra® HT Submersible Heater is designed to provide a comfortable environment for your aquatic fish, featuring an electronic thermostat that automatically maintains a consistent water temperature of 78 degrees and prevents overheating, thereby extending the heater's lifespan. With an indicator light, the heater lets you know when the water is heating (red light) and when it reaches the proper temperature (green light). The interior of the heater is equipped with silicon carbide crystals, which improve heat distribution and transfer. The strong glass tube is heat and shock resistant, ensuring the durability of the device.

Using the included suction cup, the Tetra HT Submersible Heater can be easily attached to the inside of the aquarium wall, in an area with good water circulation. This submersible heater is available in various wattages to accommodate different aquarium sizes: the 50-watt HT10 is suitable for 2 to 10 gallon aquariums; the 100-watt HT30 for 10 to 30 gallons; the 150-watt HT40 for 30 to 40 gallons; and the 200-watt HT55 for 40 to 55 gallons. All Tetra HT heaters are UL Listed for safety.
