What is a good depth for a veggie filter ?

My VF is in two sections. One section is less then a foot deep, and the
other is a bowl shape that goes down to about 18 inches. This is part by
design, part by newbie mistake. Someday I plan on tearing it all out and
redoing it, but for now it works great.

This depth makes it easy to clean, and maximizes the root mass to water mass
ration. I get very good fallout using this setup.
