Adjustable Aquarium Heater, Submersible Fish Tank Heater with Suction Cups, Quartz Glass Heater

The aquarium heater is available in three different power capacities - 100W, 200W, and 300W - to cater to a variety of fish tank sizes. Designed with your peace of mind in mind, the heater features overheating protection to ensure the safety of your aquatic environment. Its compact design allows for efficient use of space, making it suitable for tanks ranging from 10 to 50 gallons.

To set up the heater correctly in your fish tank, fully submerge the entire unit in water and install it on the inner side of the tank. It is crucial to avoid exposing any part of the heater body or head, and to maintain the water level by adding more water regularly. Importantly, the heater must be disconnected from the power supply whenever you are changing the water in the tank.

The heater comes equipped with four super-strong suction cups, allowing for a secure attachment to the fish tank. The target temperature can be easily adjusted by rotating the knob, with a range of 68°F to 94°F (20°C to 35°C). The double waterproof design and protective cover safeguard your tank from any voltage leaks, making it suitable for both freshwater and saltwater aquariums.

The temperature-adjustable feature of this aquarium heater allows you to set the desired temperature within the range of 20°C to 35°C (68°F-94°F). Simply turn the knob to your preferred setting, and the built-in thermostat will automatically start heating when the water temperature drops 1°C to 2°C (2°F to 3°F) below the target, and automatically stop heating when the temperature rises 0°C to 1°C (0°F to 1°F) above the target.

Reliability is ensured through the use of 2mm extra-thick shatterproof quartz glass, which prevents any electric leakage. The included double-row bracket with four suction cups further enhances the stability and security of the heater's installation.

For tanks up to 20 gallons, the heater measures 11 inches in length and is suitable for both saltwater and freshwater aquariums, making it applicable for a wide range of aquaculture, marine, and tropical fish environments.

It is crucial to remember that the part of the heater below the waterline must remain fully submerged at all times. When changing the water, it is essential to disconnect the heater from the power supply. Additionally, the heater should be installed in a location with a fast water flow to ensure optimal performance and safety.
