Quick question. I recently bought a Taylor 2006K kit and and trying out the chlorine tests for the first time. When they say add drops until the sample turns clear, do they mean in the short term or after sitting for a minute or two? I've found that my water will clear up initially while stirring but then will slowly turn back to a faded pink. I'm not sure if this secondary color change is accurate or not, and I'm concerned I'm artificially elevating my readings by counting it.
