His sand is aragonite... it is not southdown (same stuff, but southdown is a trademark name.) It is in LARGE bags, and very cheap comparatively. Just make sure you rinse, rinse, and rinse, as there is a lot of very fine sediment there. It'll cut down on your waiting to be able to see the back of the tank time. It'll also help control the sandstorms if your clownfish waves the sand around or the powerhead stirs it up. I did my tank with his stuff, and it was great.
