if it's well known and studied, post the link or references. Diffusion is very slow and doesn't go very deep because the water doesn't go deep. There's no transport mechanism deeper than the surface few mms.

I make my own rocks. So, to promote diffusion through the rock and into a denitrification zone, I suggested a sponge center core within a thin rock shell... uncle objected to the fundamentals:
