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!

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!

Great product

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!

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

I have two goldfish in a 20 gallon and the bio load was ridiculous. My parms were off the charts. Ammonia and Nitrate was so high I was doing partial water changes daily to keep up. I was using ceramic, charcoal, and sponge in an Aqua Clear 30. Water was always cloudy. So I bought a nylon sock from the store and filled it with about 4 tablespoons of Purigen. I now run ceramic, Purigen, with a small amount of charcoal in a separate bag under the nylon, and foam. The first day I didn't notice a difference in cloudiness but I did notice my fish were more active. My fancy tail which usually just stayed at the top was swimming about. The next day when I woke up it was magic. I had some algae on my plants, it was literally peeling off in sheets! The water was not cloudy at all! Day three, filter sucked up sheet algae that was shloffing off and my water was so clear I could see the glass on the outside needed cleaning! So I did a water test. Ammonia 0, Nitrates, 0, Nitrates under 10ppm. That is almost a complete 360! My fish are happy, my plants are happy, I am happy. Please note, when I bought this I also changed from AquaSafe to Prime. Purigen will need to be recharged every couple of months. Using bleach then Prime. I also added Prime to my Goldfish tank when switching to Purigen. Both are made by Seachem. I can not say 100% if it was my just using the Purigen or if it was the two together that changed my tank. I highly suggest both in unison. Now using in my nano with the same results. Will be using in my SW tank as well. I did not buy their "The Bag" instead opting for a white nylon you can buy at Walmart or the like.

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

Muito bom

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.

Works really well to clean up the aquarium. Worth every penny
