I'm in Ohio. The people at the nursery said go 24 inches. Should I go
deeper? And at the risj of sounding stupid, what is a veggie filter?

IMHO, I think 3 feet would probably be safer. I am in MD, near Baltimore,
Zone 6ish. My pond is 42 inches at it's deepest. I'd rather be too deep,
then not deep enough.

A Veggie Filter or more commonly a VF, is a method of filtering your pond
using only plants. In it's simplest form, a VF is a second smaller pond
(usually comprising of a minimum surface area that is 10% of the main pond).
The VF is heavily planted with plants, to the point where all surface area
is dedicated to the plants, and not animals. The roots of the plants cleanse
the water of fish #2, #1, etc.

VF's are the Linux of the pond filter world.
