Matrixâ„¢ is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrixâ„¢ is a porous inorganic solid about 10 mm in diameter. Each liter of Matrixâ„¢ provides as much surface (>~700 m2) as 170 liters of plastic balls! Plastic bio-materials provide only external surface area, whereas Matrixâ„¢ provides both external and internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Matrixâ„¢, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.
Matrixâ„¢ is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, Matrixâ„¢ may be rinsed when needed without damaging the filter. Matrixâ„¢ 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 with Stability to more rapidly establish the bio-filter.
