The Oase BioPlus 20PPI Filter Foam is an essential maintenance component designed for owners of Oase BioPlus internal aquarium filters who want to ensure consistent water clarity and biological health. These replacement foams provide both mechanical and biological filtration, offering high dimensional stability for reliable performance; however, users must ensure they match the pore size (PPI) to their specific filtration needs, as this 20PPI variant is engineered for a specific balance of flow and debris capture.

PPI stands for Pores Per Inch. A 20PPI rating indicates a medium pore size that balances mechanical debris removal with biological filtration surface area.
No, these are precision-engineered specifically for the Oase BioPlus range of internal aquarium filters.
While the material is durable, it is recommended to replace it once it loses its ability to spring back into shape or if it becomes too degraded to clean effectively.
No, this foam provides a surface for beneficial bacteria to grow. Always rinse in aquarium water to keep those colonies alive.
Yes, many users stack different PPI ratings to create a multi-stage filtration effect, with 20PPI for coarse debris and 30PPI for finer particles.
The foam may be saturated with debris; gently rinse it in a bucket of aquarium water to dislodge trapped waste.
Ensure the filter housing tracks are clear of debris and that the foam is pushed completely into the frame.
To install the foam, simply power off your Oase BioPlus filter, remove the filter module from the aquarium, and pull the old foam cartridge out. Slide the new 20PPI foam into the designated housing until it seats firmly.
Care instructions are straightforward: rinse the foam using only old aquarium water during your routine maintenance to preserve the beneficial bacteria living within the pores. Do not use tap water, as the chlorine will destroy the bacterial colony and cause a mini-cycle in your aquarium. Replace the foams when they lose their elasticity or when the water flow remains significantly reduced after a thorough cleaning.
