Title pretty much sums it up. Unfortunately, my pool was filled by and is replenished with well water with a moderate level of iron. After a few weeks, I started noticing metal stains appearing around the pool. Did the vitamin C test, confirmed it was iron staining and conducted the AA treatment. Was a complete success; all of the stains went away. Have been adding around a bottle of Jack's Purple Stuff about every 10 days. (half bottle on day 1 other half on day 5.) As part of the AA treatment, it was recommended to keep Ph levels on the low end - 7.2 or so. I'm now 4 weeks out from the AA treatment and everything seems to be holding well. Then I realized that the Ph was below the recommended level of 7.6 - 7.8 for a SWG, per pool school.
So, my question is - which is more important: keeping the Ph low (7.2) to prevent metal stains or keeping the Ph on the higher side (7.6 - 7.8) for the health of the SWG?
