Hygger 100W Aquarium Heater for 5-26 Gallon Tanks

The heating rod is made of explosion-proof quartz glass material and a high-temperature resistant nickel-chromium heating wire with silicon carbide heat conduction, which makes the water heating faster and safer, more durable and longer-lasting. Rapid heat accumulation is achieved through this design.

Flashing LED digital display allows you to press the button to adjust preset temperatures and access more functions for flagging Low/High temperature and out-of-water warning signs. The external controller makes operation easy and safe to use. Each touch changes the set temperature by 1F(1°C), and you can press for 5 seconds to switch between Celsius and Fahrenheit.

The high-temperature protective cover made of high-quality ABS material can prevent pet fish from directly touching the heating element during swimming, providing a safety mask.

Dual suction cup holders plus a spare suction cup hold the heating rod securely in place. Please rotate the suction cup 90 degrees to install it. The heating rods can be installed underwater as needed.

The fish heater shield is made of high-temperature resistant ABS material, and the heating rod heating body is made of explosion-proof quartz glass, nickel-chromium heating wire and silicon carbide heat-conducting material. This aquarium heater is anti-corrosion, non-leakage, non-conductive, explosion-proof, and makes water heating faster.

This full immersion aquarium heater has two temperature probes built-in. When the fish heater is out of water or over temperature, it will automatically stop heating and send out a warning signal L1 or HH. The heating rod will restart after it is completely submerged in water or cooled down, providing a safety guarantee.

When the actual temperature is lower than the set temperature of the fish tank heater by 1.5°F/1.5°C, the indicator light will turn red, and the fish tank heater will heat up to the set temperature at full power. The indicator light will then turn blue, and the heating will stop. The temperature range is from 59°F to 93°F, an intelligent thermostat feature.

The external smart HD controller with LED digital display allows you to operate the submersible heater without getting your hands wet. Each press of the controller will change the set temperature by 1°F(1°C), and you can press and hold it for 5 seconds to toggle between Celsius and Fahrenheit.

The 100W aquarium heater is suitable for 5-26 Gal fish tanks, both freshwater and saltwater. It has a memory function that remembers the temperature you set it to when the power fails. THREE suction cup brackets can stably fix the heater in every corner of the fish tank.

When using the heater, make sure the heating rod is completely submerged in water and there is enough water flow and water circulation in the fish tank. This will ensure safe and efficient operation.
