Step 4
Place the heater into your aquarium, in an area that water will never go below the ‘minimum water line’. The heater must be oriented vertically, horizontally, or in between. Gently press the heater and suction cups onto a clean glass surface in the desired spot. Ensure that the aquarium water level is monitored on a daily basis to ensure the water level does not go below the ‘minimum water line’. Ensure that there is proper water circulation around the heater, so it performs optimally.
