Hygger Fully Submersible 800W Aquarium Heater for 80-190 Gallon Marine and Freshwater Tanks

The External Digital Display Controller features an easy-to-use LED digital screen that simultaneously displays the set temperature and the current aquarium temperature. Users can set the temperature within a healthy range of 59 to 93°F using the button and monitor the heater's performance in real-time.

The Double Tubes Heating Element boasts a shatterproof quartz glass tube and a nickel-chromium heating wire for fast, steady, and more evenly distributed heat. It also includes a PC plastic guard to protect fish from being burned if they come into contact with it.

The heater is equipped with Running Dry Shut Off Protection, which means it is completely submersible and will stop working when exposed to air, displaying an E1 error code. Once the heater is placed back in the water, it will reset itself and resume operation.

The Overheating Protection feature automatically turns the heater off and displays an HH error code when the water temperature reaches 95°F, and it will remain off until the temperature drops to the set level. This ensures accurate temperature control within a 1°F difference.

The 800-watt aquarium heater is suitable for use in both freshwater and saltwater tanks, ranging from 80 to 190 gallons. The package includes two suction cups that can be easily installed vertically or horizontally underwater, at a depth of less than 5 inches.

In summary, this comprehensive aquarium heater provides a range of advanced features, including digital temperature display, dual heating elements, safety shut-off, and temperature control, making it a reliable and efficient choice for maintaining the ideal water conditions for your aquatic life.
