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.

KEY FEATURES:
High capacity biofiltration
Controls ammonia, nitrite, and nitrate
Highly porous - enormous surface area (>~700 m2/L)
Supports aerobic and anaerobic bacteria species
DIRECTIONS:
Use 250mL of Matrix for each 200L (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.
