I own the Taylor K-2006. I still occasionally take my water to the pool store to have them test it. Needless to say, they are always way off of my weekly readings that don't fluctuate much. I guess everyone reads results differently. I believe that I am right but I still have a question to make sure I am reading a few tests correctly:
How do you judge when the color changes? With the Alkalinity and Calcium Hardness, there seems to be a point that the color you are looking for shows up. I add another drop and it changes to that color a little more. I add another and it changes again. At this point, I can keep adding drops and it does not seem to make a difference.
Which one do I go with?? When it first changes or a few drops later when it hits that stable color????? Don't rake my over the coals too bad for asking. I am a little color blind and do my best
