Jim,
I have sent the MS Word version of my flow diagram via e-mail to you.
Hope it helps,
With my Vegetable filter media I have used Granite stones and the plants seem to love it and my mate has used 10mm pea gravel washed first.
We both have upward flow through the roots and out over a waterfall return to pond.
