Seachem Laboratories MatrixCarbon Activated Carbon Media 100 mL

Keeping your fish in clear, comfortable water does not always call for a big container of media, and that is exactly where this size fits in. Seachem Laboratories MatrixCarbon is an activated carbon offered here in a compact 100 ml portion, formed as a spherical bead instead of ordinary loose granules. That small quantity makes it an easy choice for smaller tanks, for a single filter chamber, or for trying it out before committing to more.

• It is formed as a spherical bead for optimum hydrodynamics, so water flows through smoothly rather than getting blocked.
• Seachem notes the beads will not pack, helping your filter hold a steady flow over time.
• It permits maximum water flow and contact with its high density of macroporous binding sites, so more of the carbon stays in contact with your water.
• It has a very low ash content, which Seachem links to its minimal impact on pH.
• The brand states that even when added to distilled water, it does not raise pH above 7.0, helpful if you keep a close eye on your readings.
• Seachem says that although all carbons contain phosphate, MatrixCarbon has the lowest detectable leachable phosphate content of all major carbon brands 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 100 ml size is well suited to nano tanks, small filters, or a top-up between larger refills.
• It slots into your current filter wherever water moves through the media.
• It handles the routine task of removing dissolved organic matter from your aquarium.

If you keep a smaller setup or just want a manageable amount of carbon on the shelf, this 100 ml of MatrixCarbon delivers the same spherical-bead design in a size that is easy to use and easy to store. Tuck it into your filter, let the beads go to work, and give your fish water that stays clear and inviting. Every performance point above comes straight from Seachem's own description, so you know exactly what you are putting in your tank.
