7. Maintenance
Regular maintenance is crucial for the longevity and efficient operation of your filter. Always unplug the filter before performing any maintenance.
- Filter Sponge Cleaning: The internal filter sponge should be cleaned regularly, typically every 2-4 weeks, depending on the aquarium's bioload. To clean, unplug the filter, remove it from the aquarium, and detach the filter casing. Rinse the sponge thoroughly in old aquarium water (not tap water, as chlorine can kill beneficial bacteria) to remove accumulated debris. Do not use soap or detergents.
- Impeller Cleaning: Periodically, check and clean the impeller and its chamber. Unplug the filter, remove the filter casing, and gently pull out the impeller. Clean any debris or mineral buildup from the impeller and its shaft using a small brush.
- Reassembly: After cleaning, reassemble the filter components, ensuring the filter sponge and impeller are correctly seated. Secure the filter casing.
- Reinstallation: Place the filter back into the aquarium, ensuring it is fully submerged before plugging it back in.
