Fluval BIOMAX bio rings have a complex pore system where beneficial bacteria can thrive. They have more capacity than most biological media, which ensures optimal contact time for greater efficiency. BIOMAX also reduces and controls ammonia and nitrite.

• Biological filter media
• Greater capacity than most biological filter media
• Also helps reduce and control ammonia and nitrate
