6. Maintenance
Regular maintenance is crucial for the optimal performance and longevity of your filter:
- Filter Media Cleaning/Replacement: Periodically check the filter cotton and activated carbon plates. Rinse the filter cotton in old aquarium water to preserve beneficial bacteria. Replace activated carbon plates every 2-4 weeks, or as needed, as their adsorptive capacity diminishes over time.
- Impeller Cleaning: Disconnect power before cleaning. Remove the motor unit and clean the impeller and its housing to prevent blockages and maintain efficient water flow.
- Surface Skimmer Cleaning: Clean the surface skimmer regularly to ensure it effectively removes debris.
- General Cleaning: Wipe down the exterior of the filter unit as needed.
Note: Always disconnect the power supply before performing any maintenance or cleaning.
