Not a lot of places around here carry sand... You can find Araglive, but there isn't much else out there, unless you buy in small quantities. Southdown is the cheapest, but you can't get it in this part of the US. I think EBay sells some live sand from the Gulf (or used to). I used to buy 40# bags of oolitic sugar sized sand in Memphis, but that was almost a decade ago... Just check around the local stores and see if anyone has any aragonite sand. You can order it, but shipping is going to be a killer.
