High capacity biofiltration.
Matrix is a high porosity biological media 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 the support nitrifying and denitrifying bacteria. This allows Matrix, unlike other forms of biological media, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.
Matrix is completely inert and will not break down. 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.
Use 250 mL of Matrix for each 200 L (50 US gallons)** of water. Matrix may be placed in any kind of filter and is particularly effective in a canister filter. Matrix is sufficiently large that no filter bag should be required for most applications. Matrix works well in drip tray systems, but you may find that the larger Pond Matrix is better suited for such applications. Use Stability to more rapidly establish the bio-filter.
**This dosage may differ from your packaging. Based on updated studies, we've found Matrix treats even more water than previously asserted.
