I just finished cleaning up 80 lbs of the coarse aragonite substrate from marco rocks. Overall I'm not disappointed with it as it's about what I was expecting. It seems to be approximately a 50 / 50 mix by volume of different grades of sand. Half is approximately equivalent to the Caribsea Special grade aragonite while the other half is a mix of the equivalent to fiji pink and oolite. I don't have a fine enough screen to separate out the smaller stuff so I can't really find out more specifically what it is.
