Leslie's titration TA test is always higher than my home, Leslie's Taylor Total Poolcare DPD Test Kit. This time I got a 60-70, they got 90! I got pH 7.6 (very happy), they got 7.8. These tests were only 12 hrs apart with no rain, water add, etc. Only bleach. Now, because I've been battling pH drift, I'm starting to wonder about my testing. Because a higher TA would explain the pH fluctuations, etc. I've even mastered continual swirl while adding drops. I've redone my TA and get same results. I make Leslie's redo, they get same result. It's got to be the titration.
I figured with the heavy rains last week my TA would drop. The color change from green is to pink or hot pink - I wouldn't call this color red ever. Any help would be appreciated.
