MatrixCarbon is a truly unique activated carbon, bead shaped for optimal hydrodynamics. This provides maximum water flow and contact with a high density of adsorptive sites without the compacting common to granular activated carbon. 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. While all carbons contain phosphate, regardless of false claims to the contrary, MatrixCarbon has the lowest leachable phosphate content of all major carbon brands tested. It out-performs other best grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorbtion, and duration of use. 250 mL will easily treat 100 gallons for several months. It is very clean and nearly dust free. The 100 mL bag size will fit any filter on the market and treats over 40 gallons. Marine or freshwater use.

MatrixCarbon's unique spherical shape prevents packing and channeling, thus increasing water flow and media efficiency.

DIRECTIONS: 250 mL will easily treat 100 gallons for several months. MatrixCarbon™ is very clean and nearly dust free. For best results, MatrixCarbon should be placed so as to maximize the flow of water through it. It may be used in a canister filter, chemical filtration module, box filter, or any high flow area of a trickle filter.
