What I do with aeration is mix in by volume.
So say I wanted 15 gallons of soil I would:
5 gal bucket of peat moss
5 gal bucket of aeration (rice hulls or per-lite)
5 gal bucket of humus
add in my amendments to the above.
Don't worry about weight.... rice hulls are pretty light as is per-lite. You want to measure by volume not weight.
When I order them it's by the lb, so to do 5 gal I'd need to figure out how many pounds to order .
