I just got my Taylor K – 2006c test kit a few days ago. Very impressive, but I do have a question about the chlorine test if I may. In step 2 they tell you to add 2 dippers of R0870 until the sample turns pink, and to add more if the color disappears. I'm guessing the goal here is to have the sample stay pink. In step 3 you add 0871 one drop at a time and swirl until the color changes from pink to colorless. My 25ml turned clear at 24 drops, however about 10 seconds later it started turning pink again so I added one more drop. Five drops later, it would still start to take on a pink tinge after about 10 seconds. Quite a bit lighter than before but still present. Should I keep adding drops until it stays clear or stop when it initially turns clear?
