Seachem Purigen Organic Filtration Resin - Fresh and Saltwater 100 ml

Removed log tannins making my tank perfectly clear. Highly recommend. Im going on 3 months and its still clear.

The before and after here are only a few hours apart-- cleared up brown water from my driftwood almost immediately. because my filter is much smaller than most (only a 2.5 gal tank) I emptied some of the Purigen in a container to save for later and then wound the bag shut again with thread. works great :)

I use this is in my freshwater tank because I have driftwood in it and dont like the color of the water with the tannins. Within 24 hours it made my water look amazing, bright and WHITE if that makes sense. I did try to recharge the Purigen but could never get it back to the colorless stage like it was when it was brand new. I followed all of the directions to a tee. I put it back in my tank and over the course of the next five days I had 5 fish die :( I wont blame it on the Purigen because I did add two new fish around the same time so its possible one of them introduced something nefarious into my tank - however, I wont take a chance with recharging it again I will just use a new packet of Purigen. I have already ordered more and will continue to use because it is slightly costly but it makes a world of difference in the beauty of my aquarium which makes it worth it to me.

Amazing! Crystal clear water, happy fish, and results with Tetra water test strips are perfect in all parameters of measurements .. something that has never happened before. Ive ordered two more as backups. **UPDATE** June 29 2017: this stuff is the best! I test my tank water every 7 days, and so far the numbers have stayed well within the good range since using this product. Have only done 2 water changes, and of course had to vacuum. Changed out original Purigen pack and replaced with a new one, and have also regenerated the old one. I am still amazed. Do yourself .. and your fish ... a huge favor, and try this product.

This stuff is amazing. I dropped it into the filter of a tank that had some driftwood in it. Beforehand the water was tea colored from the driftwood. Overnight all the tannins were gone and the water was crystal clear. I then dropped it into the filter of a tank it was having an algae bloom (the water was turning murky green) and within about two days the Purigen bag was bright green but there was no trace of algae left in the tank. I followed the directions on the website to clean and recharge it and it worked perfectly. Note that if you do try to clean it with bleach you have to use the Prime product to soak it in afterwords to remove all the chlorine before putting it back into the tank. Im definitely sold on Purigen.

Recently discovered this Purigen stuff from online discussions because I always seemed to have nitrate problems. Upon using Purigen I notice my nitrates are almost non-existent! But this is also in part that I do frequent water changes and make sure to vacuum the substrate. I can see how this Purigen will help you reduce frequent water changes if your tank is not overstocked. But if you do have an overstocked tank, definitely use this stuff & keep up your regular maintenance if you want your fish to thrive for the long run :) My fish are doing friggin awesome thanks to this stuff, I highly recommend it. Thanks Seachem for inventing such an amazing product.

Literally life saving. We put a large piece of wood in the tank after soaking it for a couple weeks but the tannins were still coming out and suffocating my fish, killing my shrimp, etc. I was changing the water every 2 days until I received the Purigen. The tank is crystal clear now, works awesome, very fast, fish are lively again. Works great with a 180 mesh bag and can reuse the Purigen by carefully following the cleaning instructions on the back of the bottle.

If you’re unsure or Skeptical about Purigen as I was before buying this product, don’t be, this stuff works. I run a Fluval FX6 filter on my 120 gallon Discus tank and wanted that Crystal clear water and Purigen provided. I was actually stunned at how clear my water turned out. Just keep in mind you have to keep a well maintained aquarium for these results, but it’s worth it. I will not be without Purigen from now on. Great Product Seachem!!

Weve been struggling with fish surviving. They just kinda make it day to day. Not really active like they should be. I bought a water test kit on a whim and found our nitrate level was CRAZY high. Ordered this. Within 24 hours the water was completely different and the fish were more active! After another 24 hours, again seeing improvement in the fish. And I love the fact its rechargeable!

My aquarium was having a severe issue with cloudy water, even after cleaning the tank and filters. I added a pouch of this miracle product and literally overnight the problem was gone! I keep some on hand in case it ever happens again.
