An inch of dry material.  If you put dry in the aquarium, top it with your 
gravel, then fill, the 1" layer of soil doesn't seem to reduce in size.

Diana Walstad participates in the Wet Thumb Forums.  So far as I can tell 
right now the soil substrate folks seem to think Miracle Grow potting soil 
is fine, although the only kind I can find in this area does have 
additives.  When I set my tanks up I searched long and hard to find plain 
potting soil without additives.
