Seachem Indoor Purigen Organic Filtration Resin - Fresh and Saltwater 100 ml

So this is absolutely incredible. I placed it into the space of my filter. Basically, I didn’t touch the filter, but within the space of the filter I placed this. It fit. It is a fairly small packet. What happened after, is just amazing. My water was crystal clear. It never got cloudy or yellowish or anything of the sort. It literally solved all my issues with the water; and my fish are alive and well. I have glo fish mostly. The packet is lasting me now for almost a year, and I simply wash it once per month or so. Again, the speed with which my water got cleared and clean, and stayed that way, is within a day or so. This is absolutely recommended for anyone with an aquarium. No smell too by the way. Thank you and enjoy guys.

First time user after reading many reviews and mentions here and elsewhere and happy to report it cleared up the tea colored water after adding cholla wood. I had boiled the wood repeatedly so it wasn’t terrible but it made the water cloudy and tea colored. It was easy to add the pre-bagged purigen to the filter and it was very effective. Definitely worth the price - especially as it should be rechargeable to use multiple times in the future. Before and after pictures included, about 48 hours apart. Full disclosure, I put in a new filter to have room for the purigen bag - the one that came with this aquarium was just not big enough to hold it.

My 300-gallon tank turned into a giant pot of manzanita coffee thanks to some gorgeous but tannin-heavy driftwood. The water was so dark I could barely see the fish unless they were right up against the glass. I knew the tannins weren’t harmful, but I wanted my water clear again without spending a fortune on expensive RO water changes. So I started looking for solutions and came across Seachem Purigen. Given how bad the water quality had gotten, I added triple the recommended amount to my sump filter. Within just a few hours, I noticed a small but noticeable difference—way more effective than swapping out my sump socks multiple times. Every day after that, the water kept improving and getting clearer. Now, a week later, the tank is just about clear. I’ll be refreshing my Purigen later this week and hope the fresh batch makes things pristine. What was once murky brown is now mostly clean with fully restored visibility. I can see my fish from across the room again instead of squinting at the glass. Purigen lived up to the hype for me—it seriously saved my tank without the hassle or expense of constant water changes. I’ll definitely be using this all the time moving forward. The fact that it’s reusable and refreshes makes the expense totally worth it. Huge thanks to Seachem—Purigen is a game changer!

This stuff is amazing for removing tannins and just having overall clearer water in your tank. After I put it in my tank it took less than a day to clear everything up. It easily fit in my Whisper IQ filter with the original filter piece in there still. I will say it did make the tank a bit cloudy for the first few hours but that's because I didn't rinse it like the packaging says to but the cloudiness cleared on its own quickly and the tannins from all my driftwood is gone after only 24 hours!

Considering I've only had Purigen in two filters for less than 48 hours, this review may be too early.However, based on what I've observed so far, I think it may be of some help to others for me to let you know my initial impression.First, there's no filter media on the market that's like it. Purigen is made up of millions of tiny synthetic macro resin absorbent. These absorbents act as lock in sponges in the removal nitrogenous waste. Nitrogenous waste is the waste material from fish and plants that , along with uneaten food left to decompose is the cause enemy # 1 - ammonia. Purigen does more than remove ammonia, it also removes soluble and insoluble impurities from the water at rate of 500% more than any other product on the market. It also increase the Redox Potential in your aquarium. I had to research this, but in a nut shell - Redox is the loss of a molecule or atom to gain another molecule or atom When this happens essential minerals can't be absorbed by the fish, their immune system can be compromised making them more susceptible to disease. Redox Potential is not only a critically important part of keeping healthy water parameters and equally healthy fish - but something that's almost entirely overlooked by hobbyists. Purigen encourage a healthy and balanced Redox Potential in aquariums which helps maintain richer oxygen levels and fend off disease. I chose to try Purigen out in a tank with hazy water, it gets direct sunlight so this has always been a problem. The Purigen itself is like a soft fine powder. I can see why you need to use such a fine mesh media bag of at least 180. The Seachem media bag won't break down, has welded seams and a plastic snap around tie to prevent it from opening under water pressure. (make sure you fill the bag over a sink, that stuff can blow out everywhere) You know when your replacing media or adjusting something inside a canister filter, turn it back on and all the debris that's been stirred up blasts into your tank? Well, that's exactly what happened, I thought I would do a 50% water change and siphon the gravel. But was pressed for time. I return home an hour later and the water is completely clean - and I don't mean just clean but pristine and sparkling. Back in 2010 after I bought my first UV sterilizer, I posted about it here on Amazon. I was amazed at how in 24 hours the water had become so beautifully clear. That was nothing compared to this, it was as if I had my Diatom XL running for 48 hours straight. The water is so absolutely crystal - it's almost surreal. Considering Purigen can be regenerated over and over it's economical to boot. After six months if it's turned a dark brown you soak the entire bag in a 1;1 solution of bleach and water and it returns to it's original state. You rinse it well, soak it in water treated with Prime and you're good to go for another six months. I'm more than incredibly impressed with Purigen and have already ordered more - it's going into every filter we have.

This product really works and it’s a must to get that extra level clear water in your aquarium. The package is just a small white pouch that appears to be some sort of beads inside it. Make sure you wash it real good before adding it to your filtration system and make sure it’s after your main filters. It should be the last thing your water passes through. You might want to also order water test kits to make sure your tank is cycling correctly before adding this filter. All in all it’s a great product. The only reason I gave it 4 stars instead of 5 is because it’s expensive for 1 small pouch that you have to replace monthly. Some say you can regen it but it comes with a risk. It does make the water incredibly clear. This was on a small 10 gallon tank. Photo attached below

Excellent...thank you...

Muy buena marca y producto, combinación de Purigen y filtración, mantienen los parámetros del agua en óptimas condiciones y lo mejor es el agua cristalina que se obtiene.

after putting the purigen, can noticeably see the clarity of the water. very satisfied with the addition of this chemical filter.

This really works! My tank is fairly newly set up, with grape wood driftwood. After 3 months, it was still leeching tannins. I added a 100ml bag into my canister filter (Fluval 307) for my 4 foot tank (150L), and after 24 hours, the tannins are gone! See before and after photos!

I’ve been using Seachem Purigen Adsorbent Fresh & Marine Aquarium Filter Media for a few months now, and I can confidently say it’s one of the best investments I’ve made for my aquarium.
