I bought some frags the other day from a guy who had black sand, it looked awesome, I wish I had done mine in the black sand, His wasn't dirty, so I'm not to sure how it looks if dirty, but his wasn't real clean either and it still real good, check out the coments on his thread, Frags for sale............$5 to $50 or his name (SimilanRocks)
there were a few comments on his tank and the black sand

Black sand doesn't have the pH buffering capabilities like argonite.
