I just purchased the Taylor K-2006 kit, and am now running a first set of tests. Whereas most of the tests are pretty basic and simple to carry out, the free and combined chlorine test, is stumping me. Because it is less black and white, and requires a little more interpretation, it is giving me varying results. The instructions are to fill the tube with required amount of water and add 2 dippers of R-0870. First of all, who invented the word ''dipper'' and what exactly is it ? Am I using the spoon as a measuring spoon (2 level spoonfulls) which I am pouring into the tube, or am I simply dipping it into the pot and adding whatever is left on the stick, to the tube ? Then the instructions state ''if free chlorine is present, the water will turn pink. If the pink disappears, add R-0870 until it turns pink''. What about if it never turned pink ? Do I add the R-0870 in this case also ? Once it does turn pink, it asks to add R-0871, drop by drop, until the pink disappears. At one point, the pink does disappear, but if you wait 30 seconds or so, the pink color starts coming back again. At this point, should I be adding more drops of the R-0871, or should I assume that once it becomes colorless, albeit for a few seconds only, I have achieved my goal ? How are others carrying out this test and interpreting the results ? These are not life-altering questions, but they are causing my results to vary quite a bit. Thanks for your feedback.
