I like sand myself. I love the life in the sand, and think it looks nicer...just my aesthetic I guess. (to be fair, I have never tried BB to compare) That being said, the general consensus on HD/Lowes play sand is that it used to be reef safe a number of years ago when a brand called Southdown was available. Now the offerings are much less dependable and may have undesireable "extras" that would not be good for the tank. if you do give it a try, document what you use and post your findings.
