Matrix Carbon is made for aquarists looking for carbon filtration with bead-shaped media that allows water to flow through rather than forming a packed mass. Its stated comparisons cover both the amount of aquarium organic matter removed and how quickly and how long the carbon adsorbs it.\u003c\/p\u003e\n\u003ch3\u003eWhat is Seachem Matrix Carbon designed to remove?\u003c\/h3\u003e\n\u003cp\u003eSeachem Matrix Carbon is designed to adsorb organic matter from aquarium water. Its high density of microporous binding sites gives water contact with the carbon as it flows through the spherical beads. The product is compared with other high-grade carbons for total capacity to remove aquarium organic matter, rate of adsorption and duration of use, with results of at least two-fold in those comparisons.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIntended for aquarium organic matter removal.\u003c\/li\u003e\n\u003cli\u003ePerformance comparisons address capacity, adsorption rate and duration of use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow does the bead shape affect water flow?\u003c\/h3\u003e\n\u003cp\u003eThe spherical beads are formed for hydrodynamics and do not pack. This shape permits maximum water flow and contact with the carbon’s binding sites. The media combines that bead structure with a high density of microporous sites, the surfaces responsible for binding material through adsorption.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpherical form designed for water movement through the media.\u003c\/li\u003e\n\u003cli\u003eNon-packing beads maintain flow paths through the carbon.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWill Seachem Matrix Carbon change aquarium water pH?\u003c\/h3\u003e\n\u003cp\u003eSeachem Matrix Carbon has low ash content and a minimal impact on pH; even when added to distilled water, it does not raise pH above 7.0.
