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.
Review: A must have for a well established over populated tank - Just what I needed for my 105l tank setup,using this inside my Oase 350 thermo filter as ive got an over populated tank and wanted something that would thrive and keep the good bacteria going along with a good clean up crew this has made clean up less of a thing and only needing to do top ups. Would highly recommend and will be using in my next setups aswell.

## 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
