Aquarium Co-Op. Simply the best.

Cleared tannins in 2 days

This stuff works great. I used it on my 29 gallon tank and within two days the water was crystal clear.

It Work Great In My 40g

Crystal clear water! Amazing

Always had cloudey water in one of my planted tanks with drift wood until I started using purigen cristel clear now highly recommend this product

Since using Purigen, I've noticed less algae in my tank because it is so efficient at removing organics from the water column. I've had the Purigen sack in the bottom and top of the intake side of my Oase canister filter and it performed well in both scenarios. I'd recommend replacing the Purigen every two weeks during the first 6 weeks of the tanks life and then you can replace as needed. I buy a new sack of purigen every time I want to replace it as I've never attempted to clean it before. One important note: please rinse thoroughly before adding new Purigen to your filter otherwise it will leave a plume of white dust over your freshly planted tank.

I've struggled with green/brown water for ages. I've tried activated carbon, algae killers, adding a second filter packed with fine filter floss, and while all of these did help a bit, nothing has worked as well a purigen. I doubt I'll ever run another tank without it!

Great product, I have them in many of my tanks (:

I loved everything I received the seachem real helps with water clarity and the plant came in so healthy, great root structure. I'll be ordering soon for my next tank set up.

My water has cleared up significantly since using this product. Including the tannins from my large piece of madrona. Yay!

They carry absolutely all I need for my aquarium. They even have links to purchasing the fish.

Purigen makes water appear clearer within a day. It won’t remove all tannins, but it definitely makes the fish pop.

I use purigen on most of my tasks. It is great at polishing the water and keeping it crystal clear.

This product blew me away. Better visibility overnight.

not work welk .I waiting a week it not working my fish tank still cloud .I still wait asecond week and let see how it work or not

I tried water changes, other additives, even adding another filter to my 55 gallon tank and still had a nitrate issue. This did the trick and my water is crystal clear

I use it to clear out the tannins. Does a great job at that!

Great product but I do wish it came with 2 bags (half as big).

Seachem Purigen

This is my go to for crystal clear water in all my tanks - it’s one of the products I can say for certain makes a noticeable difference in 24 hours.

Put it in my hang on back filters a few days ago, the water looks clearer already.

I use it in all my filters in place of carbon. I regenerate it whenever it gets dark with plain old bleach.
Stuff makes my aquarium's water crystal clear.

Great

This stuff is amazing at pulling out tannins in my nano tank from Indian Almond leaves I put in there for my betta and shrimp.

Works great, arrived on time

Seachem Purigen

Wow! Purigen is amazing. I put a branch of manzanita in my tank. Before I did I boiled it then soaked it for five days. In between days I dumped tinted water out and filled the container with fresh water. I put the branch into my aquarium thinking it was fine, no more tint. Wrong. Two day later I woke up to tint in my tank. I had charcoal in the filter but it wasn’t doing the job, then I remembered I had a package of Purigen. Took out the charcoal popped in the pack of Purigen and within 1 hour my tank was almost clear. Within a couple of hours it was clear! I’ll never be without this product. And Bonus…didn’t effect the PH levels.

Works as described
