Common questions about manuals, registration, and support for this brand.
Ensure the filter case is filled completely with water before plugging it in. Adjust the flow control lever to the minimum setting for faster priming. Allow 30-45 seconds for the air to purge and the water to start flowing.
Regular cleaning of the filter case and intake tubes is recommended once a month. The motor unit should be removed and cleaned every three months to remove slime or debris buildup.
Most AquaClear Power Filter models include three stages of filtration media: AquaClear Bio-Foam (mechanical), Activated Carbon (chemical), and BioMax (biological).
Water spilling back into the aquarium over the intake usually indicates that the filter media is clogged and restricting flow. Rinse or replace the foam and carbon inserts to restore proper circulation.
