'Veggie' Filter

my pond, a 300 gal stock tank, has a birdbath filled with watercress. the
pump lifts water up through the hollow pedestal to the bowl. it feeds the
watercress and then overflows and aerates the water.

I need some information on what a 'veggie filter' should be. Some say that
the surface area should be 10 - 20% of your pond. Others say that it should
be 10 - 20% of the pond volume. Which is correct.
Also some say not to use lava rocks, others say it's okay.
What about water flow? How many gph should it have?
Should the pond water enter from the top or the bottom?

Here is what I think I am going to do:
Pond size = 1600 gallons
'Veggie Filter' = 225 gallons (2x10x1.5)
GPH Flow = 400
Pond water will enter from the bottom and cascade out the top like a
waterfall.

Will this work?

That would be a nice idea for a OT tank. Great idea using the bird bath.

thanks. it seems to work really well. in the winter i take the round mat of
watercress and put it down in the main pond where it winters over. i cover
the pond with plastic and add an airstone after i turn off the pump. of
course we don't have terrible winters out here in far southwest texas, but
it does get down to the 20s at night for about a month.

Another filter design:

Click on *My Filter* for a diagram, *Demon Pond Filter* for more pictures
and *My Lilypond* for plumbing under liner. I put Whyacinths in the
pre-filter barrel, all barrels are in the ground with only 2" showing.
Connected they take up less than a 4'X4' space. ~ jan
