I looked at walmart and the hardware places and all I can find is 4 pound bags at walmart for $11. I need 23 pounds so it seems like I should buy a 50 lb bag or so. Anyone have a good source for bulk at a great price?

So I saw that earlier too. However I saw that it is 94% CC. I was wondering if 94% is usual with normal impurities, or if they added 6% of something that might not be compatible in pools?
The SDS says its 100%. I suspect if there is something added, it's a binder to make the dust form pellets, like cornstarch or kaolin clay. Might leave a residue that gets vacuumed up.
