I beleive the fabric is designed for one way flow, ie: water gets in, but
can't get out, and I also think that it has some kind of chemical in it, to
resist weeds and the ilk.

Has anyone ever used weed block fabric for filter media or can think
of any problems with using it? I'm thinking of using it for a final
stage filtering.
