Pool stained b/c of metal. Ascorbic acid treatment worked. Chlorine pucks didn't bring back the stain. But a few days after AA treatment, I had to SLAM it b/c it was turning green, and it stained again. I did not use a sequestrant after the AA treatment. So...
You guys tell me if my next plan of attack is wrong:
1. AA treatment.
3. Pucks. No SLAM. Never SLAM!
Does that sound right?
