With Crystal Max, you achieve the best performance per liter of filter volume.

  • Extremely porous filter media made from sintered glass, with unique charachteristics.
  • Extremely large colonisable area for micro organism (275 m² per liter Crystal Max).
  • Gives a quick filter start-up, Crystal Max acts like a sponge for micro organism.
  • Harmful substances will be decomposed thanks to aerobic (high oxygen) and anaerobic (low oxygen) filter processes.


  • 800 ml is sufficient for 100 L of aquarium water and in ponds 800 ml is suffficient for 500 L.
  • Larger quantities give even better results.
  • Rinse thoroughly with clean water before use.
  • Rinse off Crystal Max monthly when you clean the filter.
  • For best results, replace after at most 1 year (depending on the pollution level).
