Tidal 55 Matrix Carbon - 140 ml (Bagged)
The 140 ml bag of Seachem Tidal 55 MatrixCarbon is the ideal powerful chemical filter media for freshwater aquariums. The high efficiency material is made up of activated carbon that has been formed into a spherical bead for optimum hydrodynamics. It will not pack together, and combined with high density macroporous binding sites, ensures a consistent flow and contact of water at all times. Features a very low ash content, which means it has a minimal impact on the pH levels within your tank, and even in distilled water the pH will not raise about 7.0. Compared to other carbon filter medias on the market, MatrixCarbon has the lowest detectable leachable phosphate content and outperforms other carbons but at least two fold in the capacity to remove organic matter, rates of absorption and duration of use.
This material acts not only as a chemical filter, but as a unique mechanical filter as well, though it is only capable of filtering objects of a molecular size. Featuring extremely minute cracks and crevices called macropores and micropores, the microporous carbon removes primarily metals and small ions such as trace minerals and are well suited for air filtration, while macroporous carbons remove primarily larger organic molecules (like nitrogenous waste) and are best suited to water filtration. Suitable for Seachem Tidal 55.
