Seachem Matrix Biofiltration Media
Seachem Matrix is a highly porous media designed to provide exceptionally efficient biofiltration for single site removal of ammonia, nitrite, and nitrate from freshwater, marine, and reef aquaria. Each liter of Matrix provides over 160,000 cm2 (170 sq. ft.) of surface, equivalent to over 40 L (10 gallons) of typical plastic ball media.
Usage Guidelines
Use 500 mL 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. Due to its large size, no filter bag is typically required for most applications.
Compatibility
Matrix works well in drip tray systems. For such applications, the larger Pond Matrix may be better suited.

I’ve used Matrix in my 200-liter reef tank for six months. The biofiltration has been very stable, and water parameters have stayed consistent. No need for filter bags, which makes maintenance easier. The media holds up well even during water changes.

It’s a solid choice for canister filters. I added 500 mL as recommended and noticed a drop in ammonia levels within a week. The surface area is impressive and the media doesn’t clog easily.

Used in a drip tray system with good results. The flow is smooth and the media retains beneficial bacteria well. I didn’t need to add extra filter media after installation.
