Glass Ceramic Bio Ring M - 5l

Glass Ceramic Bio Ring M - 5l ceramic cylinders. The cylindrical shape of the bio rings makes them the optimal filter material especially for bio filters (sump type) and large filters (canister type).

• Due to the particularly large surface area for bacterial colonization (approximately 10 times higher
  compared to conventional ceramic cylinders) optimal decomposition of ammonium and nitrate is guaranteed.
  
• Made of high-quality glass ceramic for crystal clear water
• One of the most effective bio-filter materials for years
• Suitable for fresh and salt water
