I picked up 80 pounds of natures ocean aragonite sand from pollys. 40 pounds of #0 and 40 pounds of #2. For the price it looks like some really good stuff. The mix of the two different grain sizes seems like it would be perfect for sand beds in the 2-4" range, I personally would add some #4 grain size aswell if I was going for a sand bed over 4". If I remember right 20 pounds bags are $17-18.
