those using this test kit do you find the purple color goes to blue quickly or several drops? I'm having a hard time reading the color change.

When I use mine, I keep adding drops until the color goes completely blue. I do this by adding drops until I don't see a color change. When I don't see a color change I know I've added one drop too much, and take this into account with the reading.

The change should be rather dramatic when you reach the point. It will go from pink, to purple to blue in only about 3 4 drops

thanks Dave just trying to get a somewhat accurate reading
