Maintenance
Regular maintenance is crucial for the optimal performance and longevity of your filter. Always disconnect power before maintenance.
- Filter Media Cleaning/Replacement:
- Periodically check the sponge filter media for clogging.
- Gently rinse the sponge in old aquarium water (from a water change) to preserve beneficial bacteria. Do not use tap water directly, as chlorine can kill these bacteria.
- Replace the sponge filter media when it becomes too degraded or cannot be cleaned effectively.
- Pump Cleaning:
- Disconnect the pump from power.
- Carefully remove the pump from the aquarium.
- Disassemble the pump impeller cover and remove the impeller.
- Clean any debris, algae, or mineral buildup from the impeller and its housing using a small brush.
- Reassemble the pump and place it back into the aquarium, ensuring it is fully submerged before reconnecting power.
- Filter Box Cleaning: Rinse the filter box with aquarium water to remove any accumulated sludge.
