Yesterday's results were better, somewhat. Got the PH down to 7.6, TA down to 200. I tried the CH test method of adding 5 drops of the reagent into the sample water 1st for metal ion interference, then proceeded with test. But I gave up after 50 drops & it was still pink! I will try the method today of diluting with distilled water. My fill water CH results are 875, but I didn't test TA or PH of it. I can do that though today.
