Features

  • FILTRATION: Purigen ranges in color from almost white (cream) to light yellow. Seachem Purigen is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water.
  • SELECTIVITY: Seachem Purigen is an organic filtration resin that works hard to remove nitrogenous compounds and waste produced by fish, corals, and even plants, making your water crystal clear.
  • CAPACITY: Being both spherical and macroreticular, Seachem Purigen has microscopic pores that increase its usable surface area to many times that of a purely spherical resin.
  • REGENERATION: Once Seachems Purigen is exhausted, it can be regenerated with a solution of bleach and water. The bleach will literally burn off the organics that have been removed from the tank.
  • SAFETY: Some slime coat products may permanently foul Purigen and render regeneration difficult. Do not reuse if odor of bleach/chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.

  • 5 days to PERFECT clarity
Style: Aquarium Pond Water Treatment
WOW Water quality: If you need help with water clarity without killing your fish with chemicals- get this. Be sure to use the appropriate mesh bag (180) so it doesn't escape. It is not as expensive for the pleasure of being able to see your fish or the frustration of constant small water changes on 20 gal fry tanks. ... show more

  • ^Upmost Reliable Product^
Style: Aquarium Pond Water Treatment
The price is good and reasonable and it’s really easy to use. It works super fast and its reliable, I recommend to use more than what it recommends for longer resistance. My nitrate and ammonia levels stayed at ZERO even with purigen so I definitely recommend this too anyone

  • A Game-Changer for Clear Water!
Style: Aquarium Pond Water Treatment
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! ... show more

  • Sparkling clear water with Purigen
Style: Aquarium Pond Water Treatment
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! ... show more

Works great. Been using in for a few years now and my tank water is always crystal clean. Plus you can reuse it over and over again. Keeps phosphorous levels way down.
