Seachem Matrix Biofilter Support Media

• Premium natural bio-filter support media
• Removes ammonia, nitrite, and nitrate from fresh, salt, and reef tanks
• 1 liter is equivalent to over 40 L of typical plastic ball media

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! This product is sold by volume. Cited weight is minimal weight.

Directions: Use 500 mL of Matrix for each 200 L (50 gallons) of water. The matrix may be placed in any filter and is particularly effective in a canister filter. The matrix is sufficiently large that no filter bag should be required for most applications. Matrix works well in drip tray systems, but you may find that the larger Pond Matrix is better suited for such applications.
