Hygger Aquarium Heater, 600W/800W Submersible Heater for Freshwater Saltwater Tank

Our products prioritize safety through a dual temperature control system and double insurance. This design ensures a constant temperature environment for your pet fish, even if one heating rod malfunctions.

The key features are as follows:

1. Dual Temperature Control System: Our device utilizes a single chip with two independent heating systems. If the temperature control system of one heating rod fails, the other rod's temperature control system can continue to operate, reducing the risk of a frozen fish tank caused by heating rod damage.

2. Controllable Heating Speed: The two heating tubes have independent temperature control, with a range of 64-93°F. The evenly wound 20 nickel-chromium electric heating wires provide 360-degree heat dissipation, allowing you to adjust the heating speed and power of each rod individually.

3. Easy Operation and Improved Durability: The fully submersible heater comes with three suction cups for secure installation in any corner of the fish tank. The removable outer shell simplifies cleaning, and the temperature can be adjusted by rotating the top knob. The sealed waterproof plastic casing protects the internal chip, enhancing the device's durability.

4. Accurate Temperature Control: The built-in dual temperature probes continuously monitor the current water temperature in real-time. When the temperature reaches the set point, the heating stops, and it resumes when the temperature drops below the set point. This ensures accurate temperature control within ±1°F.

Our heaters are suitable for a wide range of applications, including seawater and freshwater fish tanks, fighting fish tanks, and turtle tanks. The 600W model is designed for 66-132-gallon fish tanks, while the 800W version is suitable for 80-220-gallon tanks. When installing, be sure to completely submerge the device in water and avoid placing it on sand or gravel.

In addition to the robust safety features, we also provide up to one year of after-sales service. If you have any questions or issues, we will be responsible for resolving the problem.

In summary, our dual temperature control system and double insurance features prioritize the safety and well-being of your pet fish by maintaining a constant temperature environment, even in the event of a heating rod failure. The easy operation, accurate temperature control, and extensive after-sales support make our products a reliable choice for your aquarium heating needs.
