4. Operating Instructions
4.1 Filtration Process
The Yaubay IF01-B20 replacement cartridge utilizes a 3-stage filtration process to maintain clear and healthy aquarium water:
- Cotton: Acts as the first stage of mechanical filtration, trapping larger debris and particulate matter.
- Activated Carbon: Provides chemical filtration, absorbing odors, discoloration, and harmful toxins from the water.
- Bio-foam: Offers biological filtration, providing a surface area for beneficial bacteria to colonize and break down ammonia and nitrites.

5. Maintenance
5.1 Cartridge Replacement
For optimal water quality and filter performance, it is recommended to replace the filter cartridge every two weeks. Regular replacement prevents the accumulation of trapped debris and ensures the activated carbon remains effective.

5.2 Cleaning the Filter Unit
While the cartridge is disposable, the main filter unit (Yaubay IF01-B20) should be periodically cleaned. Disconnect power, remove the cartridge, and gently rinse the filter unit components with aquarium water to remove any accumulated sludge. Avoid using tap water directly on biological media to preserve beneficial bacteria.
6. Troubleshooting
- Reduced Water Flow or Poor Filtration:
Check if the filter cartridge is clogged with debris. Replace the cartridge if heavily soiled. Ensure the filter unit's intake is not obstructed. - Unusual Noise from Filter:
Verify that the filter unit is properly submerged and securely installed. Check for any air trapped inside the filter or impeller chamber. Ensure the water level in the aquarium is adequate. - Cloudy Water:
If water remains cloudy after cartridge replacement, ensure the cartridge is correctly installed. Consider performing a partial water change. Persistent cloudiness may indicate other water quality issues unrelated to the filter cartridge.
