Pawfly Coarse Mesh Aquarium Filter Media Bags, 8" x 5.5", with plastic zipper

At 8 inches by 5.5 inches, each of the eight aquarium filter media bags in this pack is sized to hold coarse media inside a filter. The 5 mm mesh holes let water pass while the mesh holds the media itself, and a plastic zipper closes the top of each bag.

Will these bags hold the media your filter uses?

Check the media first: the bags take large media such as bio balls, ceramic rings, zeolite, crushed coral or activated carbon. The 5 mm mesh suits pieces bigger than that opening, so fine media is not the job for this mesh.

Next, check where the bag will sit. The manufacturer lists canister filters, power filters and pond filtration systems as the equipment these bags go into, so a bag's 8 x 5.5 inch footprint needs to fit the media chamber you have.

Soft polyester mesh with a zipper seal

The manufacturer makes the bag from polyester that it describes as soft but strong, with the mesh woven coarse enough to leave 5 mm openings. Because the openings are large, water passes through while media stays behind.

A plastic zipper runs along the top. Closing it keeps the media inside the bag instead of letting it drift out into the filter, and opening it again is how you swap the contents.

The manufacturer says the bags resist wear and can be used again after washing, and that the black colour holds up rather than fading.

Filling, closing and placing a bag

According to the manufacturer, you connect the filter media together inside the bags to keep the aquarium clean. To do that, open the zipper, load the media, and close the zipper again; the same routine lets you replace the contents later. With eight bags in the pack, you can sort media into separate bags rather than mixing everything in one.
