I would go 18 inches, BV. That is the depth the books
on Veggie Filters claim is best.

Nedra, do they say why 18?

I am battled two design right now. One that has the filter about 12 inches
deep, flat bottom, with a slight slant to the middle to collect debris and
make cleaning easier. I am also thinking of a having a more sculpted bottom,
that includes different depth areas, hoping that may help in settlement.

Right now, the 12 inch deep across the board is winning. Seems the most
simple. I could be swayed to 18 though if I would gain some benefit. I just
want to keep it shallow enough that I can get in there and clean it easily.
