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. This allows Matrix�, unlike other forms of
biomedia, 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.
