Seachem Laboratories MatrixCarbon Activated Carbon Media 250 mL

If you want a manageable amount of quality carbon for your tank, Seachem Laboratories MatrixCarbon comes in this compact 250 ml size. It is an activated carbon made to help keep your fish in clear, clean water. Seachem describes MatrixCarbon as a truly unique activated carbon, formed as a spherical bead for optimum hydrodynamics, and the brand says it will not pack down the way some carbons do over time. This smaller portion is an easy way to fit it into a single filter.

• The 250 ml volume is an easy, manageable amount, handy for smaller tanks or for trying MatrixCarbon in your setup.
• It is formed as a spherical bead, which the brand says is shaped for optimum hydrodynamics as water flows through.
• Because it will not pack, Seachem notes it permits maximum water flow and contact with its binding sites.
• The brand points to a high density of macroporous binding sites as the core of its filtering action.
• Seachem says MatrixCarbon has a very low ash content, shown by its minimal impact on pH.
• The brand notes that even when added to distilled water, it does not raise pH above 7.0.
• Seachem states it has the lowest detectable leachable phosphate content of all major carbon brands it tested.
• The brand claims it outperforms other high grade carbons by at least two-fold for total capacity to remove aquarium organic matter.
• The bead shape is meant to keep water moving freely rather than clogging the way packed carbon can.
• It is designed to sit in your filter where water can pass through and contact the carbon.
• It is sold as a single 250 ml unit, a tidy fit for compact filtration setups.

Activated carbon is a quiet helper in a healthy aquarium, working between water changes to keep dissolved organics down so your fish enjoy clearer water. Place MatrixCarbon in your filter where flow can move through it freely, and let it do its work. The smaller size lets you put the brand's claims to the test in your own tank before committing to a larger amount. For fish keepers who want a smaller portion of a carbon backed by the brand's own performance claims, this 250 ml Seachem MatrixCarbon is a simple, low-commitment way to start.
