The data sheet gives a Chemical Abstracts Service number (CAS#) for it, and that is 1332-09-8. Google that number. **Q: do you need to keep this in a bag or in the tray in my cascade canister filter?** A: It can be placed in your tray. it is loose. Might want to make sure you use a tray for the canister that has the lid on it. **Q: Does it work the same way as the ceramic bio rings?** A: A million times better. The ceramic rings are trash. This has a lot more surface area because of the small cavaties in each piece. This stuff is fantastic for your bacteria. **Q: I have a Magnum 350 filter which has a canister that has charcoal on the inside and a foam sleeve outside. Do I use this to replace the charcoal?** A: No, charcoal is a chemical filter. Matrix is a biological filter.If you did not need chemical filtering in your system, you could repurpose the Magnum 350 as a bio-filter by replacing the carbon with Matrix. This would help control ammonia/nitrites/nitrates at the expense of controlling organic pollutants. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by I***3 on January 21, 2026* ### ⭐⭐⭐⭐⭐ Review *by H***T on April 27, 2026* ### ⭐⭐⭐⭐⭐ Review *by R***M on November 12, 2014* ## Frequently Bought Together - Seachem Matrix Bio Media 1 Liter - Seachem Indoor Purigen Organic Filtration Resin - Fresh and Saltwater 100 ml - Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums, 16.9 Fl Oz (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/2271706-seachem-matrix-bio-media-1-liter](https://www.desertcart.dk/products/2271706-seachem-matrix-bio-media-1-liter) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-02*
