Seachem Matrix High-porosity Biomedia Filter Media

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 USgallons) of water. Matrix may be placed in any kind of filter, and is particularly effective in a canister filter. Matrix is sufficientlyLarge that no filter bag should be required for most applications.
