• 【Automatic Temperature Control】When the submersible heater detects that the water temperature has reached the set temperature, it will automatically turn off, and once the heater detects that the temperature is lower than the set temperature, it will automatically start heating to keep the temperature constant.
• 【All accessories】1pc aquarium heater, 3pcs suction cups and 1pc stick-on thermometer. 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.
