20 Liter Matrix Biological Filtration Media
Matrix is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrix media is a porous inorganic solid with an average particle size of about 10 mm in diameter. Due to the specialized internal structure, each liter of Matrix can yield more than 700 m2 of surface area! 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 to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.
- High capacity biofiltration
- Controls ammonia, nitrite, and nitrate
- Highly porous - enormous surface area (>~700 m2/L)
- Supports aerobic and anaerobic bacteria species
Matrix is completely inert and will not breakdown. It need not be replaced. That said, it is possible for Matrix media to become clogged with detritus and slime, so we recommend regular filter maintenance to ensure it continues working as efficiently as possible. Since the majority of the bacteria are internal, Matrix can be rinsed to remove detritus without damaging the filter.
Use 250 mL of Matrix for each 50 US gallons (200 liters)* of water. For best results, Matrix should be placed so as to maximize the flow of water through it. It may be used in a media reactor, canister filter, box filter, or any high flow area of your sump where water can be effectively directed through the media. Matrix is sufficiently large that no filter bag should be required for most applications.
*Note: This dosage may differ from your packaging. Based on updated studies, Seachem found Matrix treats even more water than previously asserted.
