- 10 ppi ultra-coarse Pre-filter foams effectively remove debris prior to water entering the main body of the filter, reducing filter maintenance
- Optimize your BioMaster filtration by using these pre-filter foams based on your aquarium’s needs.
- Timing to replace the pre-filter foam set varies upon aquarium size, number of fish and plants, and declines in filter performance. We recommend replacing the foams incrementally.
- The 10 ppi foams are pre-filter foams for all BioMaster models
