I really like the black sand. It hasn't 'salt n peppered' as much as I thought it would, and I love the different look and the way it makes certain corals pop and stand out. I will probably keep up with the black sand for my next tank as well. I think it hides other algae and stuff a bit better than normal 'white' sand also. But if you are meticulous about anything not purely black being in the sand it may drive you crazy. Both are definitely cool, but if you want to try out something different, go black! Not saying once you do you will 'never go back' but its definitely fun so far haha.
