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.

Seachem Purigen 100 mL is a must-have for any fish tank. It does a great job keeping the water clear and clean by removing waste before it turns into bigger problems. I noticed the tank looked cleaner and fresher after using it. It is also relatively cheap for how effective it is, and a little goes a long way. Great value for the price and easy to use in a filter bag. Highly recommend for anyone who wants better water quality and a healthier-looking aquarium.

This is amazing stuff! I bought some driftwood for my tank and even after rinsing the water turned a dark murky brown. I googled a fix and this came up so I ordered. Within a few hours the water was remarkably clearer and by morning crystal clear. Very happy with my purchase! I wish I had a before and after photo to share because the change is amazing!

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.
