I think the white substrate helps a lot with lighting, black would probably make it harder to grow sps, just my thoughts on it. Would probably look hella cool though.

I have read people have issues with that sand and mag floats, the black sand tends to have magnetic particles in it that stick to and scratch the heck out of tanks, I think that's why you don't see it that often. Would look cool tho.
