Mike,
You might consider perlite if you are not able to find good enough
sand to use. As for the sand, go to your nearest swimming pool company
and ask for filter sand. It comes in 50 pound bags for about 5 bucks a
bag. Another place to try would be a sand blasting company. They
should carry the white silica sand that you need. BTW, usually pool
filter sand is silica sand. Be careful in using silica sand as it can
surely cause lung infection. Take the necessary step and wear a mask
when working with this stuff. I wet my sand down prior to using it and
I still wear a mask. Hope this helps.

As I'm sure everyone knows, sand is often called for as an ingredient in
CP planting mediums; however, I have had a lot of trouble finding a good
sand to use. The only two I have seen available are "Play Sand" and
"Potter's Helper" sand; both of these have actually been recommended to
me several times, and I have used them.
Well, recently I tested them, and they were both VERY alkaline! There
must be limestone involved. They were so strong, in fact, that in a
peat:sand(1:1) mix, they overpowered the peat and made the mix alkaline!
