Ran the numbers with my new Taylor K-2105 kit. Just for the **** of it, I took a sample by a local pool supply store to have them test. Some things were very close, but there were several differences. Salt level from my controller shows 2900, and they came up with 2200. My TA number of 90 was close to their 89, but they had another category called "Adjusted Total Alkalinity" which was 76. For CYA, I had 75 vs their 44. She printed out everything with a recommendation of what I needed. I was able to thank her and walk out the door since I was on my Harley. What do you think of the differences in salt and CYA numbers?
