When I test with my taylor "basic" test kit it shows plenty of chlorine - 3 +. PH 7.5.
When I test with TF kit, My Free chlorine is usually about one or two and CC trace or none. My TA is about 190, cyn currently about 40 and going up with sock method.
Anyway I was going by the pool store and they, alarmingly, had my PH at less than 6.6. Total chlorine at .6 and free at .1. They also think my total hardness is low. it probably is as I can find any calcium in the pool. Pool store also shows TA at 90. Which seems odd.
So, I find the PH most alarming. I have tested several times with basic kit and it is always ok. But it also shows plenty of chlorine when it is actually a bit low.
I am most concerned about my ph. It also seems ok with a test strip. Any thoughts? Is the pool store incorrect? Can I trust my PH ?
