Hi, did first time test of the chlorine levels w/ TF100 kit & curious about “turning clear”. As I added drops eventually solution went from pink to what I’d call a “cloudy” clear, no pink but not crystal/see through clear. After setting 30 sec or so the previously clear sample had a very slight pink tint. Does the amount of drops to turn clear begin the instant the sample clears up or when after sitting several minutes, it remains dead clear, no tint at all? Thanks for any help!
