SeachemIndoor Purigen Organic Filtration Resin - Fresh and Saltwater 100 ml

Our fish tank is in a room with many windows. Although it rarely gets direct light, the algae is out of control in the tank. Within 3 days of a water change, the tank water is green, the walls are green, and it looks like a murky mess.I upgraded my filter to the aqua clear 30, and with their filter media I saw zero difference. Many people said to remove the carbon filter in the filtration basket and add purigen. I wasn’t sure how big the purigen pouch would be so i ordered mesh bags which were not needed at all. The purigen pouch fit perfectly in my aqua clear 30 filter basket after I removed the carbon. Within 2 days my water went from green to CRYSTAL CLEAR! Days later the water looks great! I will still have to do algae maintenance on the glass, but I’m in awe how the water is perfect now! I also like how you can reuse the purigen by cleaning it with bleach.

This stuff is the stuff of dreams! I have never had clearer water. I now run it in all of my filters, both freshwater and saltwater. I love that you can also recharge it after use to keep it going for longer! Well done, Seachem!

We have a 75 gallon tank with SEVERAL pieces of driftwood. The amount of tannins leaching out was insane. We’ve used about 6 in total to achieve full water clarity during the cycling phase: 4 to start and 2 more to maintain. It is definitely worth it. Just make sure to follow the instructions and rinse these out very well before use or else you risk cloudiness for a couple of days. I learned that the hard way when using in another tank. The fish were fine, just didn’t look too great.

If I could give this product 10 STARS I would. This product is amazing & super easy to use. Amazon has the best price for purigen. Lowers negative numbers on water test clears all the cloudy water & makes aquarium look like 4k tv. AMAZING STUFF

I find this product, very easy to work with and less expensive as well. I had a very hard time with the chunks in the Seachem title 35. I took them all out and replaced the bag and my tank crashed so I put half of them back in loose and then the new bag and it took three or four weeks for my tank to come back from the edge of oblivion. When I put this pure product in instead, I still left a few of the Seachem chunks in the filter; maybe four or five. I have had no tank crash! My water looks spectacular my corydoras are so happy They kept laying eggs and now I have several healthy, happy baby coreys! I think the mother Is the Long fin variety & The other two are green Coreys. They chase my long fin all the time, So I assume that she is the mother of the eggs and now the babies. Two are brownish And one has some distinct green on him. I’m curious to see how they grow up. But back to the filter. I have suffered with probably 30 filters in my fish keeping years. I’ve had everything from the 3 gallon to a 55 gallon tank. For some reason this measly 10 gallon tank has been a nightmare as far as filtration. But an intelligent young man from my LFS recommended the Seachem Tidal 35. He uses it in all 25 of his tanks. He also cleans and takes care of other peoples tanks as a side job. And he loves Corydoras! I was really afraid I’d made a mistake by listening to him, but it just takes the right filter media to make all the difference in the world. And the right filter. And someone knowledgeable & friendly to steer you in the right direction.! I highly recommend this product and I hope that you give it a shot. What do you have to lose besides a messy tank and a couple of dollars? Who knows you could end up with surprise fish fry!!!!!!!

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.

This stuff is amazing! My tank went from gloomy yellow water to crystal clear overnight!!

First time trying this over activated carbon. So far, I like it! Comes highly recommended by users to clarify water!
