Pool has a vinyl liner with fiberglass steps, so there is no plaster in the pool. Pump has been running 24/7 since I first attempted the AA method in mid July. The steps are the first place I notice any stain reappearance, and I do have a return directed to the steps mostly to move leaves toward the skimmer.

I believe the cloudiness originally began with the double dose of the HEDP after AA cleared the stains. I had gotten feedback that I may not have used enough HEDP on the first try. Cloudiness cleared in about 4 days. Water clarity now is very good. Still keeping ph low at 7.0.
