Seachem Matrix Carbon Tidal Filter - Activated Spherical Carbon Bead 190 ml

FILTRATION: MatrixCarbon by Seachem is a truly unique, bituminous coal-based, activated carbon, formed as a spherical carbon bead for optimum hydrodynamics and will not pack.. DENSITY: MatrixCarbon permits maximum water flow and contact with its high density of macroporous binding sites.. IMPACT: MatrixCarbon has a very low ash content as indicated by its minimal impact on pH. Even when added to distilled water, it does not raise pH above 7.0.. CARBON: MatrixCarbon is not only a chemical filter, but a mechanical filter as well due to its ability to mechanically filter out objects of molecular size, functioning through macropores and micropores.. USE: 150 mL of MatrixCarbon will easily treat 400 L (100 US gallons) for several months. Use MatrixCarbon in a filter bag and rinse before use. For best results, MatrixCarbon should be placed so as to maximize the flow of water through it. This product may also be used in a canister filter, chemical filtration module, box filter, or any high flow area of a trickle filter.
