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.

Key Feature:

• Designed for use with the Oase BioStyle Hang On Filter range
• 30 PPI replacement filter foam
• Provides both mechanical and biological filtration
• Large surface for bacteria colonisation
• Replace every 12-18 months or as required
• Replacement foams are available in a 2-pack or 4-pack

This 30 PPI BioStyle Replacement Filter Foams come as standard in all BioStyle models and should ideally be replaced after 12-18 months, depending on aquarium size, stocking density of fish and plants, and overall filter performance.
