We have a 20k gallon vinyl lined in ground pool. For a year we have been battling staining. It tests nearly 0 for iron and copper and pool store insists it's manganese because we leave open in winter with heavily wooded yard. All of our chem levels are perfect after getting super high phosphates under control. Only thing low is calcium. City water. Used Stainfree and metal free, liner was perfect but water cloudy. Tried floc and Revive but never cleared. When started adding chlorine, stain slowly returned. The whole liner with light tan stain. See photo. Any ideas on clearing water and stain?
