Zip Bag

These are very good quality bags, I was sceptical at first due to the price but I like them. First off I see a few reviews saying they are no good for Purigen, this is correct as you will the The Bag that is about £10 that is a 180 micron mesh bag for Purigen, secondly reviews are saying these are not small as stated, the size Small or Medium refers to the size of the holes in the bag not the size of the bag in fact both are exactly the same size and can hold over a litre of filter media. I got these on sale so it was 2 bags for just over £6 so I am happy and would buy again at that price.

Actually received this item yesterday, its not small as it stated 12 x 5cm...... far from it, its actually pretty big so will have to fold it 3 maybe 4 times to use but im sure it will be ok? anyway it really is a good product.

Perfect for holding some phosguard in my nano tank.

Purchased before really good quality perfect for purigen and other media for external filtration

First of all - this is not a bag specially for Purigen. This is a mesh filter bag with a zipper that you can buy from any Temu/ Aliexpress like 10 - 20 of them for £4. And secondly - purigen leaks from the bag goies into your water, your fish start to eat it and die. So buy this on your own risk. I did everything according to instructions - went £25 for 250ml Purigen and now £3.74 for the bag and what this purchase gave me is endless water changes and I still can't clear the water from these small white balls. And bear in mind that this was between my biological media and just before 2 baskets with fine fleece filter media, which means it went through them as well. My opinion is that it is not worth the money if it's not gonna work with the expensive bag that's made for it.

Really disappointed in this. I bought this because the bag that came with my purigen split. I tried researching to see if this was a suitable replacement and when I asked Seachem I was told that yes, this would be fine. Its not. The purigen beads still come through the mesh of the Zip Bag sm. I really don't want to keep having to replace the full lot when it is supposed to be designed to be refreshed.

As headline , a bit expensive but does the job of keeping the media in the bag and not the aquarium.

Just what I wanted to put PhosGuard in.

I didn't quite realize this would be longer than a ruler's length. 4 stars because the size is listed, but I would not be any means call this "small". I'm using it with my Seachem Tidal 55 and I had to really wrap it around itself to be able to fit it in the basket.

Excelente calidad

Ist schon geil, das Wasser wird dadurch saubere 👌

Not listing the micron size is not good, do not buy if you are planning on using it with purigen. It leaked out the bag

Bonne qualité, juste surpris par la grandeur du sac,qui est plus grand que se que pensait donc j'ai du le plier pour le mettre dans ma pompe.
