I think you've provided a truly magnificent example of why it's impossible to "get it right" when you depend on pool store testing. As is often the case, the CYA test results are the most random. But, neither you nor I -- nor the pool stores -- have any certain knowledge of what your pool chemical levels are.

Have you ordered a K2006, yet?
