Its inert, durable granules provide superior internal and external biofilm space, outperforming traditional plastic media by a factor of 170 in surface area, ensuring long-lasting, maintenance-friendly filtration compatible with all filter types. ## Description Matrix is a high porosity bio media that provides efficient bio filtration for the removal of nitrogenous waste. Matrix is a porous inorganic solid about 10 mm in diameter. Each litre of matrix provides as much surface (>~700 m2) as 170 litres of plastic balls! Plastic bio-materials provide only external surface area, whereas matrix provides both external and internal macro porous surface area. These macro pores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows matrix, unlike other forms of bio media, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter. Matrix is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, matrix may be rinsed when needed without damaging the filter. Matrix is compatible with all types of wet or wet-dry filters. ## Features - High capacity bio filtration - Controls ammonia, nitrite and nitrate - Supports aerobic and anaerobic bacteria species ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0033Q1U7A | | Allergen Information | Abalone Free | | Best Sellers Rank | #4,931 in Pet Supplies ( See Top 100 in Pet Supplies ) #221 in Aquarium Fish Food | | Brand Name | Seachem | | Customer Reviews | 4.6 4.6 out of 5 stars (2,227) | | Global Trade Identification Number | 00000116011600 | | Included Components | Seachem Matrix Bio Media 250ml | | Item Form | Granules | | Item Type Name | Seachem Matrix Bio Media 250ml | | Item Weight | 3.2 Ounces | | Liquid Volume | 250 Millilitres | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 000116011600 | | Model Number | SC Matrix 250mL | | Number Of Items | 1 | | Number of Packs | 1 | | Pet Type | Fish | | Target Species | Freshwater Fish | | UPC | 000116011600 000116112505 | | Unit Count | 250.0 Milliliters | | country-of-origin | USA | ## Product Details - **Brand:** Seachem - **Item Form:** Granules - **Item Weight:** 3.2 Ounces - **Liquid Volume:** 250 Millilitres - **Number of Packs:** 1 ## Images ![Seachem Laboratories Matrix Bio Media Granules, 250 ml - Image 1](https://m.media-amazon.com/images/I/61G3JxZL8CL.jpg) ![Seachem Laboratories Matrix Bio Media Granules, 250 ml - Image 2](https://m.media-amazon.com/images/I/41zR7q35XKL.jpg) ![Seachem Laboratories Matrix Bio Media Granules, 250 ml - Image 3](https://m.media-amazon.com/images/I/41kv4+yHF6L.jpg) ![Seachem Laboratories Matrix Bio Media Granules, 250 ml - Image 4](https://m.media-amazon.com/images/I/41u0CEfGmBL.jpg) ![Seachem Laboratories Matrix Bio Media Granules, 250 ml - Image 5](https://m.media-amazon.com/images/I/21-HlMumo6L.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - Seachem Matrix Bio Media 250ml - Purigen & Matrix Bio Media 250ml - ALEGI Media Filter Bag Aquarium Extra Fine,Reusable 180 Micron Drawstring Mesh Filter Bags for Very Fine Resins Filter (7.5"*3.6" (3 Pack)) --- ## 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.pt/products/78387839-seachem-laboratories-matrix-bio-media-granules-250-ml](https://www.desertcart.pt/products/78387839-seachem-laboratories-matrix-bio-media-granules-250-ml) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-25*
