If it were available here, I would certainly try it. I've seen some all black sand in the local gardener's outlet, haven't tried the stuff yet though, it runs about $5 (canadian) per 2L bag. This is a little too pricey I use "The Answer" potting sand it is a nice dark gray colour and is about $2 for a 4 1/2 liter bag, This should be more commonly available as I bought it at Home Depot.
