Important Setup & Maintenance Advice

Crucial Priming Step: Because this is a Hang-On filter, it cannot be run dry. Before plugging the filter into the electrical socket, you must manually fill the rear filter casing with aquarium water to "prime" the pump. Failing to do so can cause the motor to overheat and burn out.

Routine Care:

To ensure a continuous "big water output" and extend the life of your pump, routinely rinse the internal filter media and clear the inlet pipe of any trapped plant matter or debris. Always unplug the filter from the power supply before performing any maintenance.
