While I really appreciate all the advice, I am getting really frustrated. This is the 2nd time in a month I have done the entire AA treatment, and after just 4 days of following it to the T, my metal stains are starting to appear again, which I confirmed by simply dropping a pinch of AA in the area. Following is a log of everything I did. There must be something I am missing. Please jump back into this thread and help me.
Thurs 7pm 1.5lbs AA, added CuLator pack to skimmer
Thurs 10pm 2qts Metal-Free (instructions say 1qt/20k gal, and my pool is 27k, so there was extra put in)
Sat 10am 1qt Poly-60, added poly-fill to skimmer
Sat 8pm FC 0, added 69oz bleach, pH 7.2, TA 60
Sat 2PM FC .5, added 48oz bleach
Sun 8am pH 7.4 - added 10oz Muriatic Acid, TA 40 - added 8lbs baking soda
Sun 10am FC 0 - added 60oz bleach, pH 7.2, TA 60
Sun 12pm FC 1.2, added 28oz bleach
Sun 3pm FC 0.6, added 48oz bleach
Sun 6pm FC 1.2, added 35oz bleach
Mon 8am FC 1.4, added 38oz bleach, pH 7.6, added 17oz Muriatic Acid
At this point I was really questioning my testing, so at 10 am Monday, I had water tested at pool store, and found pH 7.4, FC 1.0, TA 70, CYA 20, oh and since now they do metals with the computer, they found 0.1 iron, 0.2 copper, they also said my CC was .45 (I ran out of the reagent for this test and have not been testing for CC lately)
Apparently my CYA test was way off, so around 4:30 pm after work, I added 24oz Muriatic Acid, waited 4 hours, then added 1/2 gal liquid stabilizer, waited 4 hours and at 1AM added 48oz bleach.
This morning (Tues), my tests are FC 2.4, pH 7.2, TA 70, CYA 30, but I am going back to pool store for another CYA test, since they now do it computerized, so not as subjective.
I am confused as to why the staining is back, why my pH kept going up. Only thing I can think of is that my pH reagent was a couple years old, and past the exp date. But I bought a new one, and ran 2 tests comparing old to new, and did not see much difference. The only thing that was really off was the CYA assuming the pool store test was accurate. Any thoughts?
