Used as a filtering material for self-made filtering equipment in a pond

It is used as a filtering material of self-made filtration device of the pond. I kept using it for about a year, and I could not tear it with a high pressure washer for several times (with some deformation). It is pretty strong. If you leave such as summer as soon as you leave it will be green with plankton Thanks to the pond, thanks to transparency (instead of the early packing in the summer instead) It is a feeling of permeability and poor water permeability even if you wash before breaking.
