Seachem Purigen Organic Filtration Resin - Fresh and Saltwater 100 ml

I’ve been looking for something to get rid of the tannins in my tank due to a large piece of Mopani wood. I was doing ~70% water changes once a week to try and keep the water clear. I put the Purigen in my filter last night and 12 hours later my tank is CRYSTAL clear. Purigen is now a product that I’ll always have on hand.

It’s 1 Tablespoon per 10 gallons. It is difficult to find small bags with mesh fine enough not to leak the tiny pellets (no matter what the bag manufacturer says) so I suggest you either use a piece of pantyhose to make a bag or get the pre-bagged purigen (which treats 100 gallons) cut a corner and squeeze out the amount you don’t want, dispose of the rest, double over the top where the hole is and clip it securely. You don’t want to be trying to vacuum up tiny pellets from your tank. It costs about 10$ so knock yourself out!

Cleared all the tannins out of my tank in a matter of days but for me it only lasted maybe 2-3 weeks tops before I had to replace with new purigen. I would say it’s great if you just need to clear up some tannins from new driftwood but might not be the best for long term use unless your willing to go through the process of ‘recharging’ the purigen as other reviewers have mentioned

Works great, if you want clear water buy this, you wont regret it.

My water was very clear to begin with, but now I cant even see the flow pattern in my tank because of how much clearer Purigen made it. Its easy to use, works with ferts and CO2, and you dont need a lot of it to see the effects. Cool that you can recharge it when it gets dirty. Wont ever be as clean as new, but you can get it pretty clean. Or just buy a new pack when the time comes. Totally worth the investment, and Ill be running Purigen in all of my future tanks. Just be careful when using Purigen with medication and slime coat enhancers. I would recommend using a separate quarantine tank for treatments, but if not, be sure to take the Purigen out before treatment. It can absorb chemicals from meds and slime coat enhancers that can become toxic and leach into your water over time/after you recharge your Purigen. I got this info from Seachem Customer Support.

I have mopani wood in my tank and it stains my water nearly red. Purigen makes my water crystal clear within hours. It’s a little on the pricier side but it’s reusable if you clean it properly

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.

Ive been running this in a couple of my tanks for several months now. I replaced the Purigen in two tanks and added Purigen to a third that had never had it. Even my wife and kids noticed how the clarity of the water (which I thought was already clear) improved with the addition of Purigen. I have four large goldfish in a 40 gallon tank and I had just done a water change a couple of days before. Granted the water was cloudy because, due to a leak in the tank I had an algae buildup on the glass which I had just cleaned up right before the water change. After adding the Purigen, the next day the tank looked brighter as if I had turned up the light on it I just had occasion to recharge or replace my Purigen for the first time. The recharging instructions arent complicated but are a little scary. You add chlorine bleach to it which means you must thoroughly dechlorinate it. Most people seem to pull this off just fine, but I did find a couple of message boards where people had left residual chlorine and killed their coral. Im not running a salt water tank, but for around $8.00 a bag and one bag lasts 6 months, I figure I can afford to replace this rather than replace a whole tank full of fish. I think its still cheaper than charcoal, more effective and because of the color change you can tell when its time to replace or recharge it. Maybe next time I will actually try recharging it. I actually went through the process, but then I was scared to put it back into the tank.

This stuff is incredible!! I have a simple 10 gallon aquarium with a basic filter, plastic aquascape and 5 guppies. The filter box came with a sponge filter, carbon filter, and a bag of bio balls. The Seachem Purigen is meant to replace the carbon filter. It starts working almost immediately. Within just a couple of hours, you can really start to see a difference in the clarity of your tank. And by 24 hours later, just AMAZING!! So crystal clear and the fish are livelier and overall look better. This is the second one Ive purchased. The last one lasted about 6 months. I know that you can regenerate them, but I just prefer to purchase a new one. Highly recommend!

Like many people, I was confused when I received this product because it was very different to what I usually purchase in the store. The mesh bag was longer and and the package it came in was a lot larger. After seeing many 1-2 star reviews claiming the product was counterfeit, I decided to reach out directly to Seachem. Heres what they said: We did briefly try out a a new bagging method for the Purigen packs. However, we have since gone back to the older version. It is not counterfeit! Simply a change from Seachem. Since it is online however, there is no telling whether you will receive the original size or this trial change. For people who expect specific dimensions this could be inconvenient. To sum up, I managed to accommodate for the different sized bag, and needless to say it is working just as spectacularly as I remember Purity working.
