Matrix is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste.

  • Matrix is a porous inorganic solid about 10 mm in diameter.
  • Each liter of Matrix provides as much surface (>~700 m2) as 170 liters of plastic balls!.
  • Plastic bio-materials provide only external surface area, whereas Matrix provides both external and internal macroporous surface area.
  • These macropores are ideally sized for the support of nitrifying and denitrifying bacteria.
