Results of Ascorbic Acid Treatment for Stains

[JimK]

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.

Thanks Ben.

It looks like my lower dose of HEDP is working, so I'll re-evaluate the cost of just maintaining a lower level of HEDP vs. only adding HEDP when adding salt plus the cost of the Culator + skimmer socks (I have questions about these which I'll post in a new thread as to not hijack this thread).
