Box Contains water treatment Review: Phenomenal biological media—a must-have for a healthy tank! - I bought this Seachem Matrix to add to my main Fluval 307 external filter, and it has been absolutely brilliant. It is highly recommended in the fishkeeping world for a reason, and now I completely see why. The biggest benefit of this stuff is its incredible surface area. Unlike standard ceramic rings that are only smooth on the outside, Matrix is packed with thousands of microscopic internal pores. This means it provides an absolute massive amount of space for beneficial bacteria to colonize and grow. It handles ammonia and nitrite like an absolute champion, keeping the water parameters perfectly stable and safe. Plus, because of its unique structure, it even supports anaerobic bacteria deep inside the pores, which helps knock down nitrate levels too—something very few other media can actually do. It doesn't clog up, it doesn't degrade or wear away over time, and it fits perfectly into the Fluval baskets without restricting the water flow at all. It honestly takes your filtration to a whole new level. If you want a healthy ecosystem and crystal-clear water, this is the best upgrade you can give your filter. Easily a 5-star product! Review: Platinum Standard Bio Media! - I use Matrix across all four of my aquariums, and it’s become my “buy once, trust always” biological media. It’s reliable, easy to use, and delivers the same steady performance no matter which filter I drop it into—canister, HOB, internal, or a sump basket. What I notice in day‑to‑day use The fish stay happy and the water stays stable. Matrix gives beneficial bacteria tons of room to colonise, which helps process waste efficiently and keeps parameters on an even keel. It’s properly “set and forget.” Once it’s in place, I don’t have to babysit it or swap it out every few months. A quick rinse in old tank water during maintenance is all it usually needs. It doesn’t crumble or compact like some ceramic rings. The pieces keep their shape, so flow through the media stays consistent. Ease of setup Rinse it once to remove any dust, pop it into a media bag, and place it after your mechanical stage (sponges/floss). That way, debris is caught before it reaches the Matrix, and the bacteria get clean, well‑oxygenated water. It works in small and large amounts—handy if you’re seeding a new tank or boosting capacity in an established one. Maintenance & longevity I only swish it in tank water when I’m doing a water change. No fancy routines or chemicals required. Because it lasts for years, it’s great value. You’re not constantly replacing media, so the cost evens out quickly—especially if you’re running multiple tanks like I am. Performance tips from my setups Don’t overpack the media bag; allow water to flow through freely. Keep a decent mechanical pre‑filter ahead of it. Less gunk on the Matrix means healthier bacterial colonies and less cleaning for you. It’s not a substitute for water changes, but it makes the system far more forgiving between services. Verdict Matrix is my go‑to for a reason: consistent results, low effort, and excellent durability. After trying plenty of alternatives, this is the one I trust across all four aquariums. For me, it’s the platinum standard of biological media—simple, effective, and worth every penny. ## Features - Warning:Not suitable for children under 10 months. - High capacity bio filtration - Controls ammonia, nitrite, and nitrate - Supports aerobic and anaerobic bacteria species - Model number: 020096 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002A5VIO | | Allergen Information | Gluten Free | | Best Sellers Rank | 8,568 in Pet Supplies ( See Top 100 in Pet Supplies ) 109 in Aquarium Water Treatments | | Brand | Seachem | | Brand Name | Seachem | | Country Of Origin | USA | | Customer Reviews | 4.7 out of 5 stars 7,671 Reviews | | Global Trade Identification Number | 00000116011709 | | Included Components | all | | Item Form | Solid | | Item Type Name | Aquarium Filtration Media | | Item Weight | 1.67 Pounds | | Item form | Solid | | Item weight | 1.67 Pounds | | Liquid Volume | 1 Litres | | Liquid volume | 1 Litres | | Manufacturer | Seachem | | Manufacturer Part Number | 117 | | Model Number | 117 | | Number of Packs | 1 | | Pet Type | Fish | | Target Species | Reptile | | UPC | 000116011709 716184580831 | | Unit Count | 1000.0 millilitre | | Unit count | 1000.0 millilitre | ## Product Details - **Brand:** Seachem - **Item form:** Solid - **Item weight:** 1.67 Pounds - **Liquid volume:** 1 Litres - **Manufacturer:** Seachem ## Images ![Seachem Matrix Bio Media, 1 Litre - Image 1](https://m.media-amazon.com/images/I/71O+7DlSbKL.jpg) ## Questions & Answers **Q: How is this used exactly? is it genuinely effective at reducing nitrate levels? my ammonia and nitrite levels are a perfect 0ppm. thank you!** A: Yes it does work I used it for months without an issue. My levels reduced as tap water was high I got a 75% reduction but don’t take that as you will get the same results **Q: Do the granules float in water** A: These are not granules **Q: I have a sponge filter (shrimp tank) with nowhere to put this in the filter. Can I just put it directly into the tank?** A: Yes although it's not ideal. Generally bacterial media is kept free of stritus by mechanical filter media, you can't do that if it's lose in the tank. If you have choice I'd certainly give it a go and see how it works. **Q: May I put 4l in a fluval fx6 to replace filter media ?** A: I tried this about 12 months ago not worth the money at all didn’t make much difference to my water quality and most the media is hard grey stone which is basically just stone and has no use in your filter at all. My advice would be go with alphagrog e25 as it’s only £23 for 20 kg and is much better I now have a mix of alphagrog and bio home ultimate and won’t look back. This is just my opinion good look with what ever media you choose to go with ## Customer Reviews ### ⭐⭐⭐⭐⭐ Phenomenal biological media—a must-have for a healthy tank! *by E***Z on 13 July 2026* I bought this Seachem Matrix to add to my main Fluval 307 external filter, and it has been absolutely brilliant.
