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.
