Aquarium Heater 1000W for 150-300 Gallon Fish Tank

The shell of the AQQA aquarium heater is made of PC plastic, much more heat-resistant than ABS material, and can resist up to 180°C. The heating rod is made of explosion-proof and insulated quartz glass, with double sealing and waterproof features to prevent water and electricity leakage, ensuring greater safety for both humans and your beloved fish.

AQQA's aquarium heater adopts a nickel-chromium heating wire, featuring fast heating and high precision temperature control. The heater will automatically power off when the set temperature is reached and will start heating again when the water temperature is 1°F lower than the set temperature, always providing a safe and comfortable living environment for your fish.

You can install the heater at any angle using the two powerful suction cups, just make sure it is fully submerged in the water. The external temperature controller allows you to easily set the desired temperature - press the button for 3 seconds to switch between °F and °C, and with each press, the temperature will adjust by 1°F/°C, allowing you to make adjustments without getting your hands wet. (Please note that the controller is not waterproof.)

The aquarium heater is equipped with an advanced protection system, including anti-dry heating and overheating protection. If the heater is not fully immersed in water, it will stop heating and alert the user, with the controller displaying "E1". Additionally, if the water temperature exceeds 95°F/35°C, the heater will stop heating and alert the user, with the controller displaying "HH". These features effectively protect your fish from the risk of overheating and scalding.

Please note that the aquarium heater must be fully submerged in the water, but do not bury it in the sand or mud. Placement near the water's flow area is recommended to prevent uneven heating. It is also important to unplug the power supply when cleaning the fish tank or changing the aquarium water. If you encounter any issues, please feel free to contact us.
