Hygger Adjustable Fish Tank Heater with Intelligent Auto Shut-off, LED Display for Saltwater & Freshwater Aquarium

Crafted from explosion-proof quartz glass, high-temperature resistant nickel-chromium electric heating wire, and quartz sand thermal conductive material, this aquarium heater is designed for rapid and even heating. With a voltage of 110-120V and a power of 800W, it maintains temperature accuracy within +/- 1 degrees.

The external digital LED display controller allows for precise monitoring and adjustment of the set temperature, which can be fine-tuned between 59-93°F. The running red light indicates the heater is actively heating, while the white light signifies the water has reached the desired temperature. The LED screen clearly displays the current power and any error codes, enabling you to easily monitor the heater's working status.

To ensure comprehensive protection, the aquarium heater is equipped with three intelligent safety features. The "off-water warning" function automatically shuts off the heater if it is not fully submerged, while the "over-heating warning" and "low-temperature warning" features flash "HH" and "LL" respectively, and the latter also triggers an alarm, to alert you to potential issues.

Designed for convenience, the heater remembers the temperature setting, eliminating the need to reset it after a power outage. Measuring 11.8" x 2.8" x 1.4" with a 10.1ft power cord, the heater comes with suction cups and a mounting bracket for easy installation, and is recommended to be placed at a 30-45° angle for optimal use with a water circulation system.

Suitable for 80-220 gallon tanks, this submersible fish tank heater is ideal for marine saltwater, freshwater, fish tanks, turtle tanks, betta tanks, and small ponds. With a 12-month warranty, the hygger team is committed to providing reliable customer support and resolving any issues you may encounter.
