use polyester fiber. but dont put it in a side chamber and divert only
some
of the water there. my veggie filter doesnt do well with fines either

later in the summer when the roots really get to the bottom and the fines
are what I clean up outof the veggie filter in fall. Ingrid

The problem with a fibrous filter is that it will clog and require
cleaning, which was the problem with the previous set up. I suppose it
could be laid on top of the main filter media as the last layer before
cascading back into the pond.
Does your veggie filter contain any earth, or is it purely a hydroponics
system? Which plants are best, ones that put out a really dense mat of
roots?
======================
I find the roots of Pickerel and Parrot's Feather do a great job in the
veggie-settling-tank. Once a month I flush the muck from this tank. It has
a bottom drain. The plants are not potted in soil - just gravel. The roots
of the Pickerel and PF are soon all through the tank. It's a 40g I think,
and the pond is 2000g.
