Excellent Water Polisher and Long-Term Filtration Support

Seachem Purigen has worked very well in my 30-gallon tank for polishing the water and keeping it looking clean and clear. The improvement in water clarity is noticeable, especially compared to standard mechanical or chemical filtration alone.I like that I can run two units in rotation—one in the tank while the other is being regenerated. That makes it very cost-effective over time since the media can be reused instead of constantly being replaced. They come prepackaged in a mesh bag so all you need to do is put in in the water (ideally in line with the flow to the filter).Overall, it’s a simple but highly effective filtration upgrade that helps maintain consistently clear water with very little ongoing cost or maintenance.Ver más

It works amazingly fast!!!

Amazing product. Like many customers have said all over the internet, that this product has been working for them and those reviews go back over 10 yrs. I must say this product continues to excel. I used this for my baby red ear cumberland slider. In less than 24 hrs the water went from a tinged color and cloudy to clear and it’s still cleaning my tank. (I didn’t take a before picture sorry) It’s removed all the tannins and my baby seems happier. I already have both an ammonia removing and carbon filters installed, so I put the Purigen bag between both. Instructions say to put the bag at the end of the filtration system where the waterfall section is but since i have the ammonia remover there I securely put the baggy in between both (see picture). I’m still finishing up our baby’s tank. But will add a final picture once I’m done decorating.Update: finished decorating our baby’s tank. Bag keeps working. I’d recommend buy minimum of 2 bags so you can switch them out when recharging the dirty one. It’s also recommended to not use continuously but on and off to let good bacteria grow. I read it on a well known forum Reddit.Ver más

Purigen By Seachem For Unsurpassed Water Quality

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 atomWhen 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.

Absolutely a MUST for any aquarium with water

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.Ver más

A Great Way To Produce Crystal Clear Aquarium Water

This is a great product for creating crystal clear aquarium water. Used in tandem with proper aquarium filtration, Purigen granules are placed in an aquarium bag and placed inside your hang on back or cannister filter. The Purigen granules remove water impurities like tannins to produce clear water. It is very easy to use and the results are noticeable in a few days. Over time the Purigen crystals turn brown from the impurities that they have removed from the water. These brown crystals can be regenerated by soaking them over night in unscented bleach and then soaking over night in clean water. Follow the instructions carefully. A great, easy to use product for beginner or experienced fish keepers.Ver más

Great with live plants, excellent regeneration process.

I found the most difficult information to retrieve was if this product works as well when you have a planted tank. I tested myself and I can say that after two weeks my plants still growing without any sign of nutrient deficiency.I really waned to give this product 5 stars. However, I've been told that it does not much more compared to a carbon filter (which I never used so I personally cannot compared). I really like it tho, and I really suggest it to buy if you don't like to mess with carbon filter and replace it every 2-3 weeks.As the product say it absorbs all the organic compound in the water. I have some piece of drift wood in my tank, and the water was starting to get pretty cloudy. I insert the media in the filter and after 12 hours I could see the magical difference. The water got incredibly clear. After a week the nitrogen level went down to zero (I had NO3 at about 15ppm).The down side is that my starting water was pretty cloudy (my fault), and the product absorbed a lot of it. After two weeks the bag looks pretty brown. I think I will have to do the cleaning process pretty soon. I will wait until the bag turn completely brown, or the water start to look cloudy again.The company claim that which 100ml you can use it for up to 100 gallons for about 4 to 6 months. I think is a little bit over estimating the range.I read several review that do not trust the cleaning process using bleach, and then soak it with de-chlorinator, I will update my review once I do a cleaning cycle.Other than that I recommended this product to two of my friend that have nitrogen or cloudy water. And If it was the case I would definitely buy it again.Update 4-8-13: I have the filter in place for almost 2 month, and it still keep the water clear. My tank is currently overstock, and I have no issues at all with water quality. I did not have to replace any filter cartridge. And I have not done the regeneration process.Great product.Update 4-24-13: I was starting to get the water little bit cloudy, so I decided to do the famous regeneration process. As soon as I dip it into the bleach/water solution it turned incredibly white. I let it soak for 24 hours, then took it out and soak in the Prime/water solution for 8 hours. After I took it out it didn't smell like chlorine at all. I wasn't sure so I dip it into some water for a bit, and test the water. Zero chlorine at the end. I place it back in the filter.There are few companies out there that make really good products for aquarium. Seachem is one of the best and one that you can always trust. You get your money worth on any of their products.
