225 micron thin-mesh aquarium filter bags are perfect for new setups and after heavy maintenance or whenever there is a lot of particulate matter in the water.

They are also suitable as a holder for other mechanical or chemical filter media.

The monofilament construction of these bags makes them very easy to clean.
