On the play ground sand, just as an extra point. The play ground sand is mainly silica, quartz and other materials (which will probably be detrimental at a later stage and surely will add nothing to your reef) where aragonite is mainly calcium carbonate. The extra benefit is that the aragonite slowly dissolves in the water which buffers your pH and calcium/carbonate concentrations.
