Hi Rich,

A veggie filter is a container full of plants through which the pond's water is
passed through.
The roots catch the mulm and process toxic 'waste' into plant useable matter.
The larger plants also use up much of these nutrients and deny algae (green
water) the chance to multiple.

My veggie filter is as simple as floating water hyacinth in my mech/bio filter.
Others have more
elaborate and wonderful systems that I'm sure they'll post.
