A veggie filter can be as engineered to have all sorts of marginals planted or
placed in its own pond or dyi lined box (most bang for your buck).
And it can be as simple, as mine, which is floating water hyacinths in the top
of your filter.

It *could* have watercress in baskets in your filter if whomever is eating them
would STOP!
Mice and snails are both suspects of interest.
