Aquarium Heater for Freshwater & Saltwater

Explosion-proof Quartz Aquarium Heater: Equipped with the latest aerospace technology, the 300W Aquarium Heater features a heating element composed of two explosion-proof quartz glass tubes and high-temperature resistant nickel-chromium heating wires, ensuring fast, consistent, and evenly distributed heat. Housed in V0 grade ABS flame retardant plastic, the fish tank heater boasts IP68 waterproof, corrosion resistant, and high-temperature resistance properties, making it stronger and more durable.

Overheating & Out of Water Protection: The aquarium heater is designed with advanced safety features. When the heater head is 2 inches (5 cm) out of the water, the heater will automatically stop heating, and the controller will display the "E1" and sound a beeping alarm until the heater is completely submerged in the water. Additionally, if the water temperature exceeds 34°C/94°F, the heater will automatically stop heating, and the controller will display the "HH" and sound the beeping alarm until the water temperature drops below 34°C/94°F.

Precise Temperature Control System: The aquarium heater features a precise water temperature sensing system, with two temperature sensors on the heating rod and a newly upgraded additional temperature probe. The Automatic Constant Temperature Function ensures that the temperature accuracy is ±1°F, automatically stopping the heating when the water temperature is higher than the set temperature and restarting the heating when the water temperature is lower than the set temperature.

Digital LED Controller: The adjustable fish tank heater offers a user-friendly digital LED controller with a temperature range of 63-94°F/17-34°C. The temperature can be set using the "+" and "-" buttons (long press the "+" and "-" for 5 seconds to switch between °F and °C). The LED display can simultaneously show the current water temperature and the set temperature, with the red light indicating heating start and the green light indicating constant temperature. The memory function automatically retains the previous setting when the heater is restarted, eliminating the need for repeated setup.

Wide Range of Use: This 300W fish tank heater is suitable for 20-80 gallon fish tanks, with a tank water heater length of 6.8 inches and a voltage of 110-120V. The heater can be widely used in freshwater and saltwater fish tanks, turtle tanks, and aquariums. The strong suction cups on the heater guard make it easy to install the aquarium heater, without the need to attach it to the tank walls or bottom. The manufacturer provides a 12-month warranty, ensuring customer satisfaction and peace of mind.
