Joann,

As a first veggie filter, it will work fine. And then you can add another
and another, as the number of plants outgrow the preform, or the fish load
requires more filtration.

??? I am going to enlarge my pond to 3000 - 4000 max gals. Can I use one
of
my preforms (250gal, 18" depth) to make a veggie filter? Joann
