Seachem Matrix Biofiltration

Seachem Matrix Biofiltration –

Above all, Matrix™ is a high porosity bio-media that provides efficient biofiltration for the removal of nitrogenous waste. Matrix™ is a porous inorganic solid about 10 mm in diameter.

Each litre of Matrix™ provides as much surface (>~700 m2) as 170 litre of plastic balls! Plastic bio-materials provide only external surface area, whereas Matrix™ provides both external and internal macro-porous surface area.

These macro-pores are in fact ideally in size for the support of nitrifying and denitrifying bacteria. This allows Matrix™, unlike other forms of bio-media, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.

Key Features:

  • High capacity biofiltration
  • Controls ammonia, nitrite, and nitrate
  • Highly porous – enormous surface area (>~700 m2/L)
  • Supports aerobic and anaerobic bacteria species

Matrix™ is in fact completely inert and will not breakdown. It need not be replaced.

Since the majority of the bacteria are internal, Matrix™ you may rinse when need be without damaging the filter.

Matrix™ is consequently compatible with all types of wet or wet-dry filters.
