I gather that salt from some sources introduces iron into pool water, and it wouldn't take much iron, per bag, to have a problem by the time you add 10 bags.

I guess a prudent, low risk, step would be to add a small dose of HEDP along with any major dose of salt, and to keep a Culator in the skimmer (under a skimmer sock) for a week or so after adding salt.
