Hmmm...what is considered "high chlorine levels" for this test? At the time, my TC was 3-5ppm. My TC is 5ppm+ now because I added bleach. Come to think of it, when I tested my make up water, the TC of that was 1.5ppm and the test worked fine. So should I trust the pool store numbers in this case? (until I get a better test kit, that is). 55ppm of Calcium really isn't that much, and I'll always have my FC/TC around 5ppm.
