## Description

Seachem Purigen, 100 ml

Review: Important for clear water in a nice aquarium - I use it regularly, cleans the water fantastically, the charcoal is the one of the past now we have this product, excellent great does what is required and more, quality (make sure you have a mesh bag it makes it easier) try it and you will not be disappointed all the best to this respectable and serious manufacturer (I am not against charcoal There is room for him too.)
Review: 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.

## Questions & Answers

**Q: Can somebody please tell me (a newbie aquarium keeper) if this product takes the place of other media or is it meant to be used in addition to the other media? Thanks!**
A: It can definitely be used as a replacement for your carbon/charcoal.  I've been raising fish for over 50 years.  I know a bit about what works, and what doesn't.  I've been using a 100ml bag of Purigen in an Aquaclear 20 (sponge, Purigen, bio-rings, no carbon) on a 5 gallon tank with about 50 guppies, about 50 small Mystery Snails, 3 Cory's, and a host of MTS, some Windelov Java Fern, water Sprite, Susswassertang, and dwarf salvinia.  Yes, the tank is unbelievably overcrowded, and I'm constantly giving away fish, snails, and plants.... But everything inside is thriving, growing and breeding.  My softened water is definitely on the acidic side, and Kh and GH are very low, but everything thrives in totally clear water, with no carbon necessary. I do a 1 gallon water change every week or two. Purigen can and probably should be used in place of carbon.

**Q: Does this purigen come in a bag that is ready to be placed into the filter, or do I need to buy a separate filter media bag for it?**
A: Yeah it does come with the Seachem Purigen in a the bag so you can just rinse it under tap water and place it straight into your filter. I recently bought myself another bag of Seachem Purigen and Seachem has updated their packaging which I found very cool. If you're looking for the Seachem Purigen to come ready to go then this is the right size for you (100ml) go ahead and purchase it. If you ever buy the bigger size Seachem Purigen it will come lose in a bottle and then you have to buy something to keep it in. You can always make your own media bags out of women's panty hose or something that can keep the Purigen trapped while still allowing water to pass through.

**Q: I have the Eclipse 38 Gallon tank, Marineland Cartridge H.  Looking to see if this might fit!  Thanks for the help!**
A: The bag comes filled with Purigen and it is small (shipping size is 4"x3" so the bag is about that size).  Nothing special to the bag so if a small bag loosely filled with fine material will fit into your filter, you will be fine.  I actually hang my Purigen at the opening of the filter so the water flows across it.  I have another filter and I put the bag on top.  You do not want to pack it into the filter because the particles are not coarse enough to allow for water flow.  The water will not flow through the material if the bag is tightly packed into your filter.

**Q: Does anyone know the dimensions of this product? 
I'm wanting to use it in my existing filter, and I'm not sure it will fit.
Here is my filter:

Also, this is already …**
A: Yes, it is ready to go.  There is enough give in the bag that you can squish it in there. I don't use carbon so I sandwich it between the sponge and the ceramic beads and I still have room.  Love the stuff! And it can be regenerated!

### ⭐⭐⭐⭐⭐ Purigen By Seachem For Unsurpassed Water Quality
*by P***K on March 25, 2012*

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.
