Seachem Purigen for Freshwater, 100 ml

Ok so I recently had two problems one the filters that came with my rank were hopeless so I had to upgrade to a Fluval 406 which is great by the way. I tried to use as much of the older filter media as possible but fully expected a mini cycle and an ammonia spike due to the change. For the last week I had also been plagued by slightly cloudy water more noticeable when viewing the tank lengthways but still annoying ! So in went the Fluval about three days later in that went the Purigen. Readings taken before the Purigen showed a slight ammonia spike at .25 and nitrites also high and nitrates at about 40 so basically not good! 24 hours after the Purigen went in these were at 0! The other thing as you will see is it has visibly cleared the slight cloudiness after 48 hours this is almost completely crystal clear even when the tank is viewed length way so it works! Apart from this it has also done something which I don't really know how to describe but everything just looks more vibrant it's like I went from standard definition to HD. I think cost wise it's reasonable. Especially when compared to say Chemi Pure which to treat my tank would cost close to 40 pounds with one pouch if Purigen is actually more than enough for my 300 litre tank. I am still running normal carbon as this extends the life of the Purigen and also Purigen fits easily into my Fluval 406.Now for the caution bit. I was actually considering taking one star off for this because I don't think Seachem make this clear enough unless you do your own research which I did but many don't ! Once finding numerous threads on the internet about two serious issues I wrote to Seachem who have clarified and confirmed so this is straight from Seachem.Issue no 1 . Many water conditioners that are used today in water changes contain a slime coat element which contains amines. This could render the Purigen useless. To be on the safe side you need to use a water conditioner which does not have this ingredient like Seachem Prime, or remove the Purigen from the filter during water changes for about 24 to 48 hours. To be clear using a water conditioner that contains amines won't create any toxicity but will reduce the effectiveness of it and also saturate it so it is not capable of being recharged.Issue number 2. If you use a water conditioner containing amines which many do, then if you use this to regenerate your Purigen it will make it toxic and kill your fish. It is hard to know whether or not a water conditioner contains amines one that is safe is Seachem Prime. Amines are not necessarily listed on the ingredients as there are variations of this chemical. I know that the Fluval and Tetra water conditioners are both not safe to regenerate Purigen.What happens if you try to regenerate your Purigen with one of these water conditioners is a chemical reaction which will trigger highly toxic chloramine in your tank. As I do not intend to reuse or regenerate my Pugin this is not a problem for me but I have switched to using a different water conditioner just to be on the safe side. I really do think that Seachem should make this clear to people purchasing this product as the consequences could be catastrophic.I will continue to use this product as it seems to really help with water clarity and chemistry but I will be purchasing a new bag when this one runs out. I suggest if you do want to use this product switch to Seachems water conditions also either Prime or Safe to get the most out of it.

Amazing product that made water crispy clean. I had wood and wood made my tank yellow. It looks amazing now.

Added new wood to my tank and the water went a awful brown colour. After reading the reviews on purigen i decided to try it. It cleared all tannins from my tank within 24hours and its remained clear. Very happy, well worth the money.

Within 2 days the water was crystal clear!!!! 5✨️✨️✨️✨️

This proved very effective at removing bogwood colouration - the tank was crystal clear after a couple of days. The company also have an excellent information department who quickly and clearly respond to questions. I bought a food filter (100 microns) which works well, but a gentleman commented that a stocking works so this might be a cheaper option. The product is expensive but I suppose that depends on how long it lasts. Whether or not you can recharge it is not clear from the comments; most are not positive and I am nervous about the possibility of introducing bleach into my tank (aren't we all?).So a good product but rather pricey. More comment on the recharging issue would be welcome.

Perfect. I had a large piece of drift wood which was giving off a lot of tannins and turning the water dark orange. This cleared it up in no time and continues to keep the water clean.I haven't tried "resetting it" as you get a healthy amount in the container and I don't have any bleech. So I just replace it.

2 months cycling tank and everyday dirty water tank fully cycled after a month used carbon after for a month and still got yellowish tint everyday with 1 driftwood in tank even though was doing daily 30% water changes. Switched to purigen and within few mins water was getting clear its been a week and water is still crystal clear no water changes ammonia is 0.

Took about 2 days and sped if up with 2 water changes.
