Hygger 500W Fully Submersible Aquarium Heater for 65-120 Gallon 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 heater is equipped with a Double Tubes Heating Element, which includes a shatterproof quartz glass tube and a nickel-chromium heating wire for fast, steady, and more evenly distributed heat. Additionally, it has a PC plastic guard to protect the fish from getting burnt if they come into contact with the heater.

The heater is designed 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. The heater will reset itself and resume working when placed back into the water.

The heater also features Overheating Protection, which automatically turns it off and displays an "HH" error code once the water temperature reaches 95°F. The heater will remain off until the temperature drops to the set temperature. The temperature controls are accurate within 1°F difference.

The 500-watt heater can be used in both freshwater and saltwater tanks ranging from 65 to 120 gallons. The package includes two suction cups that can be easily installed vertically or horizontally underwater, with a depth of less than 5 inches.
