Seachem Laboratories MatrixCarbon Activated Carbon Media 2 L

When you want your aquarium water to look clear and stay healthy for your fish, the filter media doing the quiet work behind the scenes matters. Seachem Laboratories MatrixCarbon is an activated carbon in this 2-liter size, formed as a spherical bead rather than the loose granules you may be used to. That bead shape is the whole idea here, and it shapes how this media behaves inside your filter.

• It is formed as a spherical bead for optimum hydrodynamics, so water can move through it freely instead of getting choked off.
• Seachem notes that the beads will not pack, which helps your filter keep flowing the way it was meant to.
• It permits maximum water flow and contact with its high density of macroporous binding sites, putting more of the carbon to work on your water.
• It has a very low ash content, shown by what Seachem describes as its minimal impact on pH.
• The brand states that even when added to distilled water, it does not raise pH above 7.0, a reassuring point if you watch your parameters closely.
• Seachem says that while all carbons contain phosphate, MatrixCarbon has the lowest detectable leachable phosphate content of all major carbon brands the company tested.
• According to Seachem, it outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter.
• The 2-liter quantity suits larger tanks or aquarists who like to keep media on hand for routine swaps.
• It works in your existing filter setup, simply placed where water passes through.
• It is designed for the everyday job of pulling dissolved organics out of your aquarium water.

For the fishkeeper who takes water quality seriously, MatrixCarbon gives you a carbon media that focuses on flow, contact, and clean performance, all stated as Seachem's own findings. Drop the 2-liter portion into your filter, let the spherical beads do their work, and enjoy watching your fish in water that looks the way you want it. It is a thoughtful pick when you care about both the look of your tank and the comfort of the swimmers inside it.
