I've been using the Taylor K2106 test kit. After a month of testing, you can just look at the sample and have a good idea of how much bromine is in the water. I will add 6 or 7 drops of the reagent without stirring, and then just swirl by hand to "read" the sample. So my question is, do I or should I be continually swirling the sample when I'm adding drops, or is swirling after adding a bunch result in the same results? I do the same with the TA test. I can tell that I'll be right around 60ppm, so I just add 4 drops first and then swirl.
