  • High efficiency spherical carbon
  • Very little impact on pH due to low ash content 
  • Lowest leachable phosphate level on market
  • High removal capacity; large surface area

MatrixCarbon is a truly unique activated carbon. It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density of macroporous binding sites. 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 detectable leachable phosphate content of all major carbon brands tested. MatrixCarbon outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorption, and duration of use.

Andrew ★★★★★

After battling cloudy water for weeks, these carbon spheres cleared it up overnight without messing with my pH. The low ash content was a big plus since my discus are sensitive.

Abigail C. ★★★★★

I was worried about phosphate spikes from new carbon, but this stuff kept levels undetectable after a month. The spherical shape really seems to pack more surface area into the media bag. Definitely sticking with it for future water changes.

Carter ★★★★★

My tank's pH stayed rock steady after switching to this carbon—that low ash content is the real deal. Phosphate readings dropped to nearly undetectable too, which my corals clearly appreciate.
