    To those of you that use Purigen- what bags do you use to contain it? The mesh bags I have let it through so I just got some pantyhose to try but some still sifts through that as well. I bought the cheapest pantyhose I could find so I don't know if the more expensive ones have a tighter weave. Any suggestions on brands that contain it well would be appreciated.

    hi Richard

    I do use pantyhose but you need to carefully inspect the seams /stitching otherwise if they split your tank gets peppered in the stuff
    and I always change to a new one after the bleaching/ soak treatment to renew in case any of the washing and rinsing has damaged the seams at all

    if you purchase the 100 grammes size it comes in a mesh pouch and for my smaller set up I am happy with the convenience this gives me.
    if you purchase the 250 size then you get in in tubs

    Seachem have a product called "The Bag" which is designed to accomodate the product

    if you have the product in an area of water flow in the sump or in a cannister , then provided it is not a crazy flow rate, the pantyhose should keep in in place provided the seams are not compromised

    Purigen make there own bags just for this, any store that sells it in the larger amount should have the bag.

    home depot sells micron bags for very cheap. they are not as fine as the micron bags at your LFS but they will probably be about $10 cheaper. I think the really good micron bags at my LFS are like $15+? Where as I paid like $3 for mine at home depot.

    I use mine for holding about 12 tablespoons of high grade active carbon in a medium flow area

    Thanks. I did see the Seachem bags but hoped the pantyhose would work. The beads don't pour out, but some did come through as I was rinsing it. I think I will need to the one of "The Bags" before I use it in a high flow filter.

    I have always just used the regular carbon bags and just doubled up on them and I have never had an issue with any of it getting out of the bags that way

    Even the purigen that comes in its own bag will have a few beads come out of the pouch when you rinse it. As long as its not in a super high flow area it shouldn't leak into your tank. I wonder if doubling up the panty hose would work?
