It has been about a year since I had flourite black sand, but if I had to pick from those I would say it looks like reef flakes / mini flakes mixed. It does have a fair number of smaller particles mixed in though. Grand select are definitely bigger than it. Much to my annoyance it also has the occasional red particle mixed in too.
