Ok, so I have a question...Today when figuring out our PPM chloramines, we were getting lower Total CL numbers then our Free CL numbers. We use the PalinTest method of testing the water, and nothing has changed. Our Tablets are fresh and good, and 4 out of our 6 pools got the lower numbers. What could possibly cause this? We even re-ran the tests on the pools in question and got the same results. Anyone have any ideas?
