Non silica sand source?

[PMolan]

Looking for a cheap non silica sand for a remote deep sand bed in NNJ. As I understand HD & Lowes carry silica sand that will add silicates to your tank. Any arguements for silica sand is welcome. Real cheap at HD.

Glass is made using a fairly high percentage a silica sand. So by this theory your tank itself would leach silicates and I've never heard of that being a problem.
