Seachem Purigen 500ml

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

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.

I have a lot of bog wood in my tank and it suffered from tannin staining which increased after water changes. I also experienced a nitrate level increase as the tank matured. I initially researched a nitrate reducing treatment when I came across this product which assisted with the nitrate issue but also claimed to remove the tannin discolouration and polish the water. I inserted it into my filter and impressed with the clarity of the water. I am now several days following a filter clean, and the insertion of this product, and the water remains crystal clear. Normally by this stage the water would start to discolour as the tannin leached out of the wood. I initially thought the product to be slightly expensive but on reflection, even without trying to clean it when it becomes exhausted, the initial cost is still acceptable if the product lasts the predicted first time use period that is claimed.

Okay so added new wood, so lots of tannins (tannins are not harmful for fish, actually quite good for fish - especially some breeds of fish) but it's an acquired taste as to whether you like the look of it, me personally I prefer clear. This was over the span of 3 days. The first 2 photos were before and after just added puragen. Very cloudy when first added but just sit it out and do nothing. With good flow and filtration (I have the AllPondSollutions UV filter, but not using the UV light currently, only if I have a massive algae bloom which happens more with my larger tank) the cloudiness will clear quickly. The bag is good quality, no rips or holes. However was a squeeze to get it into my filter so have purchased some smaller bags and will split this bag into 2 and put 1 in my smaller tank next to it. Just as added filtration. This can be reset & reused by following instructions. Good value for money for this reason.

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.

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.

Don’t leave many reviews but had to for this. I’m brand new to keeping an aquarium and didn’t soak the wood ornaments properly which resulted in tannins. Heard about this product and gave it a go. Put the bag in the filter in the evening and checked back in the morning to find a huge improvement. The bag is still working and I’m sure it will still improve. This is a must have!

I have used many liquid based water clearer such as, API Accu-clear and also nitra-zorb pouch, AND various filter sponges including multilayer sponge, those so called 5D, 9D layer sponge..... but this Seachem Purigen i got way better result to almost crystal clear water within 24 hours.EDIT: I found an alternative and MUCH cheaper and works same [Pure-Gone Organic Waste Remover]
