Seachem Matrix is a highly porous media designed to provide exceptionally efficient bio-filtration for single site removal of ammonia, nitrite, and nitrate from freshwater, marine, and reef aquaria.
Each litre of Matrix provides over 160,000cm2 (170 sq. ft.) of surface, equivalent to over 40 L (10 gallons) of typical plastic ball media!
DIRECTIONS:
Use 500ml of Matrix for each 200 L (50 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.
