What is biological filter foam?

The Oase Biological 30ppi Orange filter foams provide beneficial bacteria with a surface area to settle. The result of this mechanical and biological filtration is clear, healthy aquarium water that's safe for your fish and plants. This filter foam should be replaced in your BioStyle filter after 12-18 months depending on your aquarium size, the number of fish and plants, plus declines in your filter’s performance.
