• 【Automatic Temperature Control】This submersible heater automatically turns off once it reaches the set temperature, and restarts heating when the water cools slightly, keeping your aquarium at a constant temperature.

The strong suction cup can effectively prevent the fish heater from slipping, and we provide an additional one for replacement. The stick-on thermometer allows you to easily check the water temperature at any time.
• 【Gentle Step Heating】Even if continuous heating is required, this aquarium heater will heat for a period of time and then pause for a few minutes (the indicator light will turn off during the pause), gradually reaching the set temperature. This design helps keep water temperature from fluctuating too much, preventing fish from feeling uncomfortable and protecting their safety.
