If you have an SWG we typically recommend using water softener salt as it is usually cheap and pure. Make sure it doesn't include rust inhibitors or other extras, just plain sodium chloride. Salt specifically sold as "Pool Salt" is the same stuff, just ground a bit finer and slapped with a considerable markup. The only salt brand to avoid is Clorox, as they appear to be sourcing some of their salt from impure sources and there's been several reports of it causing staining.
