Tetra HT Submersible Aquarium Heater with Electronic Thermostat

The Tetra® HT Submersible Heater is designed to provide a comfortable environment for your aquatic fish. It features an electronic thermostat that automatically maintains a consistent water temperature of 78 degrees, preventing overheating and extending the heater's lifespan. The indicator light on the heater lets you know when the water is heating (red light) and when it has reached the proper temperature (green light).

Inside the heater, silicon carbide crystals improve heat distribution and transfer, ensuring even heating throughout the water. The strong glass tube is heat and shock resistant, making the heater durable and reliable. Using the included suction cup, the Tetra HT Submersible Heater is easily attached to the inside of the aquarium wall in an area with good water circulation, making it simple to install and use.

The Tetra HT Submersible Heater is available in different wattages to accommodate various 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, ensuring they meet safety standards.

Whether you're an experienced hobbyist or just starting out, Tetra offers a comprehensive range of quality fish food, innovative equipment, test kits, and decor to cater to all your fishkeeping needs.

The HT20 model, in particular, utilizes a built-in electronic thermostat to automatically maintain the water temperature at 78°F, which is ideal for most tropical fish species. This feature eliminates the need for manual temperature adjustments, making the heater user-friendly and hassle-free.

The Tetra HT heater is fully submersible and can be installed either vertically or horizontally, allowing for flexible placement options within the aquarium. Its compact design makes it easy to conceal behind plants or other decorations, ensuring a seamless and aesthetically pleasing integration into your aquarium setup.

It is important to read all label information upon delivery and not plug the heater into an electrical outlet until it is properly placed inside the aquarium. This ensures the safe and effective operation of the Tetra HT Submersible Heater, helping to maintain the ideal water temperature and provide a comfortable environment for your aquatic pets.
