Product Description Seachem Matrix Carbon 500Ml Directions Use 250 mL of Matrix for each 200 L (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. Matrix works well in drip tray systems, but you may find that the larger Pond Matrix is better suited for such applications. Use with Stability to more rapidly establish the bio-filter. This dosage may differ from your packaging. Based on updated studies, we've found Matrix treats even more water than previously asserted. Box Contains water treatment
