Purigen & Matrix Bio Media 250ml

The Purigen & Matrix Bio Media (250ml) combo is one of the most effective upgrades you can make to any aquarium filtration system. Purigen does an incredible job at removing discoloration, organics, and impurities — the water becomes noticeably clearer within a short time, often looking “polished.” It regenerates easily, too, which makes it cost-effective in the long run. Matrix is equally impressive. Its highly porous structure provides excellent surface area for beneficial bacteria, helping stabilize ammonia, nitrite, and nitrate levels. It’s reliable, long-lasting, and works well in virtually any filter setup. Together, these two products create a powerful filtration solution that supports both water clarity and biological stability. If you want cleaner, healthier water and a more stable tank ecosystem, this pairing is a fantastic choice. Highly recommended for freshwater and marine hobbyists alike!

Seachem Purigen is an absolute game-changer for keeping aquarium water crystal clear! I simply place it in my filter, and it attracts and locks in tannins, preventing that unwanted yellow or brown tint in the water. This is especially useful for tanks with driftwood or other organic materials that release tannins over time. One of the best things about Purigen is how long-lasting and reusable it is. Unlike traditional chemical filtration media, it can be recharged with bleach and used multiple times, making it a cost-effective solution for maintaining pristine water clarity. Since using Purigen, I’ve noticed a dramatic improvement in water quality, and my fish seem happier and more vibrant. It doesn’t strip out beneficial minerals like carbon does, which is another big plus. If you're struggling with discolored or murky water, I highly recommend Seachem Purigen. It’s an easy, effective, and reliable way to keep your aquarium looking its best!

This stuff is amazing. Took my murky water to a mirror clear appearance in just a few days. It will be a must-have in my aquarium for now on!

Great product

I can't say enough good things about Purigen. I bought some wood that was leaching a lot of tannins and turning my aquarium water yellow. I was dreading the long, tedious process of constantly washing the wood to get rid of it. But instead, I decided to give Purigen a try, and I'm SO glad I did! It worked wonders – my water is now crystal clear, and the yellow tint is completely gone. The best part? I've bleached and reused the Purigen multiple times with great success! It continues to perform just as well as it did when I first used it. This product is a total lifesaver, and I highly recommend it to anyone struggling with water discoloration. It's a must-have in my aquarium maintenance routine now. I love it!

Made the water crystal clear! Just a bit expensive but 100% effective.

You want clear water? Esp in a fresh water or brackish tank.This is what you want.Youll need to purchase a filter bag for the media.Fill it flush it .Pop it in a HOB or cannister.Give it 24 hours.Consistently good stuff

Edit: The tannins from the driftwood and Indian almond leaf were acting as a buffer, keeping my pH stable. Shortly after adding Purigen, my snails started croaking. My pH has remained consistent all that time until now (tap is pH 7.6, neither hard nor soft.) I've dosed a few times with pH neutralizer, but can't get the pH higher than 6.0. Also, the Kh is now low... Long story short: I'm going to move the snails to a different habitat, and keep a close watch to be sure my pH doesn't continue to drop. I got this to remove tannins from driftwood in my 30gal tall that's been cycled for 5yrs. My betta sorority is so colorful, it seemed a shame to dull their shine 😊 The before pic was right after a 25% wc, so it's not as tannic as usual - but still like weak tea. Less than 36hrs later, and the water is close to crystal clear! No effect to pH either (*see edit.) I like too, that it can be regenerated (but I probably will just renew it instead. But that's a great feature if you have a very large, or multiple tanks.) I used 2T in a nylon stocking as the top layer in an Aquaclear hob. Bottom to top: coarse sponge, fine sponge, ceramic biomedia, purigen; coarse sponge on intake tube. Note: be sure to rinse this well before adding to your filter. It is a little "floaty," but I expect this will go away with time. It hasn't escaped the hob though.

Sehr gutes Produkt macht was es soll das Aquariumwasser ist glasklar vielleicht etwas zu teuer sonst Nix zu bemängeln

Muito bom

Es un excelente 👌 producto para el filtro de tu pecera además es una resina reciclable de manejara muy fácil

ينحط في اكياس قماشية وينحط بالفلتر وينقي لك الحوض من كل المواد العضوية ويخلي الماء صافي بشكل مرعب

This works so well! I have fancy goldfish in planted tanks, and even with good filtration including polyfil and charcoal etc. and weekly water changes they are a lot. Maintaining water quality is challenging, and even when it was good I still had tannins from the plants. Not a problem but it doesn't look as "pretty". I added a bunch of purigen and the tanks cleared up in hours for the small (30 gallon) and two days for the large (60 gallon). Crystal clear water. I'm very impressed! It's clearly catching all the small stuff that my regular filters and siphon miss.
