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, with an electronic thermostat that automatically maintains a consistent water temperature of 78 degrees and prevents overheating, extending the heater's lifespan. This heater features an indicator light that lets you know when the water is heating (red light) and when it reaches the proper temperature (green light). The internal silicon carbide crystals improve heat distribution and transfer, while the strong glass tube is heat and shock resistant. 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.

The Tetra HT Submersible Heater is available in different wattages to suit various aquarium sizes: the 50-watt HT10 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 feature indicator lights to let you know when the heater is on, with a red light indicating the water is heating and a green light signifying the proper temperature has been reached.

The HT10 model, designed for aquariums between 2 to 10 gallons with hoods or glass canopies, uses a built-in electronic thermostat to automatically maintain the water temperature at 78°F, which is ideal for most tropical fish. No adjustment is required, making it a user-friendly option.

The Tetra HT Submersible Heater's small footprint allows for easy concealment behind plants or other decorations, and its fully submersible design enables both vertical and horizontal installation. However, it is crucial to read all label information upon delivery and ensure the heater is placed inside the aquarium before plugging it into an electrical outlet.
