Hi,
We have Brown spots on bottom of pool after switching to SWG summer of 2022. We also had the plaster redone in fall of 2021. Does the cheaper salt at Walmart vs pool store contain metals? Is there anything I can add daily or weekly to keep the metal from staining the plaster? Pool chemistry is Free Chlorine 5.35, Total chlorine 5.35, PH 7.5, TA 71, Calcium 347, CYA 42, IRON 0, Copper .1, Phosphates 215, salt 4000.
Thanks in advance,
Barb
