Matrix™ is a high porosity bio-media that provides efficient bio-filtration 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 macro-porous surface area. These macro-pores are ideally sized 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.

Matrix™ is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, Matrix™ may be rinsed when needed without damaging the filter. Matrix™ is compatible with all types of wet or wet-dry filters.
