These genuine Oase BioStyle Replacement Filter Foam Sets are designed for use with the Oase BioStyle filter range. The BioStyle Replacement Filter Foams provide both mechanical and biological filtration. Not only do the foams remove debris from the aquarium water but their coarse structure provides a large surface area ideal for bacteria to colonise. These nitrifying bacteria remove harmful ammonia and nitrite, which complements the mechanical filtration resulting in cleaner, healthier water for your aquarium inhabitants.
