If you mean this, CaribSea Dry Aragonite Fiji Pink Reef Sand, then that is what I had before too.
The best coarse sand by review is tropic eden reef flakes and
CaribSea Seaflor Special Grade Reef Sand.
Both grain sizes are bigger than standard sand that I've seen normally available at LFS in my area. I have the reef flakes and I am loving how white it is and can't tell that it's grain size is too much bigger.
It isn't being moved around with my RW8s at 70-80%. I don't have corals put down with epoxy/reef glue yet so I haven't turned it all the way up but when I have all my sps in....IT'S ON!!!!
