Matrix

Seachem Matrix is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrix is a porous inorganic solid about 10mm in diameter. Each litre of Matrix provides as much surface (>~700 m2) as 170 litres of plastic bio balls. Plastic bio-materials provide only external surface area, whereas Seachem Matrix provides both external and internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows the 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 it can be rinsed when needed without damaging the filter. Seachem Matrix is compatible with all types of wet or wet-dry filters.

Directions:
Use 250ml of Matrix for each 100L of water. It may be placed in any kind of filter, and is particularly effective in a canister filter. Seachem Matrix is large enough to be used without a filter bag 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.

Available Sizes:
250ml, 500ml, 1Ltr, 2Ltr & 4Ltr
