I was browsing some sites today, and came across this:
http://www.amazon.com/Filter-Silica...e=UTF8&s=toys-and-games&qid=1231084321&sr=8-1
It says that it's filter sand, and that it will work in pools, but I'm not positive that it's the same thing that I want. It also says that it's silica based, which I seem to recall is bad.
Any thoughts?
