Oase Aquarium Pre Filter Foam Media - 6pc

It is recommended to replace the pre filter foams every 1 to 3 months, depending on the stocking level and feeding habits in your aquarium. You may also notice reduced water flow, which indicates they need attention.

No, these pre filter foams are specifically designed for the Oase BioMaster Aquarium Filter series. Using them with other models may result in improper fit and compromised filtration.

45ppi (pores per inch) foam is coarser and captures larger debris, offering more mechanical filtration for heavier waste. 60ppi foam is finer, capturing smaller particles for improved water clarity. It is often used in conjunction with or after coarser media.

While foams can be rinsed using old tank water during maintenance, they will degrade over time. For optimal filter performance and water quality, it is best to replace them every few months rather than attempting to reuse them indefinitely.

These pre filter foams are primarily for mechanical filtration, removing solid particles. They do not typically remove dissolved chemical impurities. For chemical filtration, other media like activated carbon would be required.

Each set contains 6 individual pre filter foams.

The pre filter foams are likely clogged. Rinse or replace the foams. If using the 60ppi grade, consider switching to 45ppi if you have a high bio-load to prevent premature clogging.

Ensure you have the correct Oase BioMaster Aquarium Filter model and that you are using the designated pre-filter foam slots. Double-check that no other media is obstructing the placement.

Rinse or replace the pre filter foams. Ensure that other filter media (like biological or chemical media) are also clean and appropriately placed. Check for overstocking or overfeeding.
