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

I preach the Gospel of Purigen. I used to work for a high-end custom aquarium installation and maintenance company with a sterling reputation and worldwide recognition within the industry for the quality of their work. Many of their installations were in multi-million dollar homes and businesses where perfection was the only option. Purigen went in every filter if the client's aquarium had A) driftwood or B) could be viewed from more than one side (in which case ANY lack of clarity becomes far more visible). We began using it in most freshwater installations when its virtues became evident. It's an absolute must for removing tannin in any tank with driftwood. You've never seen the color "clear" if you've not used Purigen. It's a clarity that's almost tactile. It's a whole new thing. A couple of usage notes: First, don't skimp on something that is meant to be beautiful. Buy "The Bag" sold by Seachem specifically for this finely granulated miracle. It's reusable and you'll go through a lot of hassle by trying to get around this inexpensive purchase but with far less success. Second, while Purigen is miraculous, it can't fix inexperience, ignorance, or poor taste. If your tank is under-filtered, poorly designed, overstocked, over-fed, or contains dumb fish (freshwater parrots, for instance), you don't deserve this product. Go fix your life. Make your aquarium what it's supposed to be: study good aquarium design, hide the wires and plumbing (or use glassware), do your regular water changes, clean the glass properly, worship at the altar of Takashi Amano, and then, when people who don't care about aquariums go, "Wow, that's stunning," THEN buy Purigen and fully understand that water can look clearer than air.

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

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.
