Ive been struggling with metal staining for weeks.
My numbers are where they should be. Fc 2-3. Ph 7.2. TA is low... About 40. Ill bring that up.
Ive intentionally kept my ph in the low 7s constantly. I havent shocked the pool.
I add about half a bottle of sequestering agent each week.
Yet I still get stains coming back on a weekly basis.
Not the overall pool discoloring ive gotten before i got control of it.
But many very large spots across the pool that require a bottle of abscorbic acid to remove.
This is becoming expensive and making it harder to control my levels.
Its been going on for over 3 weeks. At this point Should I just start replacing water 1/4 at a time or something? Ive really had enough of this. Its never happened to me before in 10 years.
Thanks a lot
