Seachem Matrix High Capacity Biofilter Marine and Freshwater Tidal Filtration,White

FILTRATION: Seachem Matrix is a high porosity, inorganic solid biomedia that provides efficient biofiltration for the removal of nitrogenous waste in your fish tank or aquarium. DIAMETER: Measuring about 10mm in diameter, each liter of Matrix provides as much surface (>~700m2) as 170 liters of plastic balls! Matrix provides both external and internal macroporous surface area. MACROPORES: These Matrix macropores are ideally sized for the support of nitrifying and denitrifying bacteria, allowing Matrix to simultaneously remove nitrate along with ammonia and nitrite in the same filter. USE: Use 250 mL of Matrix for each 200 L (50 US gallons) of water. Matrix may be placed in any kind of filter, wet or dry, and is particularly effective in a canister filter while also working well in drip tray systems. International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
