20pcs Aquarium Filter Bags Media Mesh Filter Bags with Zipper for Activated Carbon, Biospheres, Ceramic Rings, Clean and Recyclable (10pcs Black + 10pcs White)

Purchased these for a aquascape to make hills ect perfect no risk of rust as made from plastic on the zips sizes are decent functionality is perfect and decent value for money Purchased two lots

They seem ok for my filter media so far, I did initially want them for a fine filter media and the mesh in these is too large so I just put my alfagrog and charcoal in them.

Bought these to put my own media and Carbon in a Juwel Bioflow 3.0 M. The bags are quite big which I wasn't expecting, but then I didn't really read the description properly. They look well made and a bargain price for how many you get. They do smell a bit funny when you open them but nothing a quick rinse under hot water didn't sort out.

Best thing I did was buy these on a whim. Great quality, value & very versatile

What fantastic value, all bags complete with plastic zips so totally reusable, bought at a fantastic price and with fast delivery. These bags are a perfect size for canister filters and would be great to use in a sump.

Great simple little bags, and great value for money. In aquarium terms you can pack a lot of media into them however I do feel they are slightly too big for purpose. But because they are mesh bags, simply folding them over and tucking the media in properly solves this issue and doesn't cause any problems with the filtration. If anything, it probably adds a little more once folded over.

Great size for filter out flow.I have a Fx6 and when I turn it back on after a clean there can be a lot of crap in the pipes.these bags catch it and I put them in the washing machine

These bags are a good idea but just beware that the holes in the mesh are a bit large and some of my carbon has come through. Make sure you buy carbon that is larger in size.
