if i'm not mistaken, the black sand will not buffer the ph as it's not a calcium based substrate.
they do have black sand bottoms in nature somewhere though. where is this sand collected?
i do believe a reflective background like white sand, will help with lighting. it works the same way that a reflector works. i do not think those caverns at the bottom of your rock scape would be so dark if you had a white sand bed fishguy. that said, i do agree with your statement about compensating for lighting.
