Thanks for getting back to me so quick and to answer your first question I am using a basic 5 test kit that only goes up to Cl of 5ppm. My water is crystal clear, just burns the eyes when you swim!

I took a sample of water this morning and tested it myself and used the shot glass method that you recommended and found that my Cl was at 12. My other numbers were pH of 7.8 and TA was at 320 according to my test results. I took a sample to my pool store and their results came up with a Cl reading of 10 or more (their results only go to 10), pH 7.8, TA 165, Hardness of 200 and CYA 100, and TDS of 1200.

I added chlorine neutralizer and the Cl is down to 4, I added muriatic acid and the pH is at 7.2 and the TA according to my test is 260. My question now is why should my TA reading be so different from the reading that they did at the store? I just purchased this kit a month ago so that I could have fresh testing chemicals so it can't be that they are old and my other tests results are right on with the store tests results. Should I purchase a test kit that measures the CYA as mine does not?
