Salifert Calcium: “a clear blue color”

So, what exactly is ment by “a clear blue color”?

Generaly it goes from pink to blue-purple, then hazy blue then clear.

Today blue purple = 0.25 375ppm
Hazy blue = 0.22 380PPM
Clear blue = 0.20 400PPM

My procedure was to add drops (fairly slowly towards the end of the titration) and swirl well for a few seconds, then stop when the last purple disappears. I think a few seconds between drops was fine for the Salifert kit.

Goes from a Dirty purple to the FIRST sign of blue. That's where you stop. One drop at a time as you near the reaction

That makes sense and seems what I have done in the past.
