Tetra HT Submersible Aquarium Heater for 2-10 Gallon Tanks with Electronic Thermostat, 50-Watt

The Tetra® HT Submersible Heater is designed to maintain a consistent water temperature of 78 degrees, ensuring the comfort of your aquatic fish. Equipped with an electronic thermostat, this heater automatically prevents overheating, extending its lifespan. An indicator light system lets you know when the water is heating (red light) and when it has reached the proper temperature (green light).

The heater's inner workings feature silicon carbide crystals that improve heat distribution and transfer, while the strong glass tube is heat and shock resistant. This submersible heater is easy to use – simply attach it to the inside of the aquarium wall using the included suction cup, ensuring optimal water circulation.

The Tetra HT Submersible Heater is available in different wattages to accommodate various aquarium sizes: the 50-watt HT10 for 2 to 10 gallons, 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.

Since 1951, Tetra has been a leader in the fishkeeping industry, developing a comprehensive body of fish food knowledge and providing products and solutions that add ease and beauty to home aquariums. Whether you're an experienced hobbyist or just starting out, Tetra has everything you need – from a wide variety of quality fish food and innovative equipment to test kits and decor.

All Tetra HT heaters come with indicator lights that let you know when the heater is on, with a red light indicating that the water is heating and a green light signifying that the proper temperature has been reached. Additionally, these heaters are designed to shut off automatically if an electrical short is detected, ensuring your safety.

The HT10 model, specifically 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.

The Tetra HT Heater is fully submersible and can be installed vertically or horizontally, with a small footprint that makes it easy to conceal behind plants or other decor. However, it is important to read all label information upon delivery and refrain from plugging the heater into an electrical outlet until it is placed inside the aquarium.
