I asked this once before and Tony very kindly gave me his response, but I am still confused on the issue. Using the Taylor Kit to measure alkalinity, the instructions read to add a drop at a time and swirl in between drops, until liquid goes from green to red. I have found that the liquid literally goes from green to pale pink to a hot pink color and then to red taking at least 2-3 extra drops after the pale pink to get to red. This means a 20-30ppm difference in my reading for alkalinity...a huge difference. To me, the pink color is very definately pink and not red so I would assume the person who wrote the instructions would have put pink, if that was where you were supposed to stop the drops and take the reading.
How do others use their Taylor Kit to read alkalinity...Tony just counts to the change from green to the first level that I would call pink.
Thanks!!
