- Suction cups for installation and placement
Which tanks this aquarium heater suits
The manufacturer recommends this model for aquariums up to 100 gallons. Because the heater is fully submersible, it sits completely under the waterline once the suction cups are pressed onto the glass.
The top of the heater has to stay above its bottom while it runs. If the top tips below the bottom, the built-in shut-off cuts the power, and it comes back on once the heater is upright again.
