Salifert Kh test question

[Patrick.S]

For those of you familiar with the salifert kh test, the instructions say stop dripping reagent when the color changes to pink. I’ve noticed that the color after changing to pink quickly returns to blue. Do you stop when it first turns pink or when it stays pink? Thanks

You stop it when it turns the color noted in this post and stays there: Alkalinity titration endpoint pH & Salifert endpoint color

I shoot for one drop more after I get the bluish/orangish/redish color change to get a solid pink/red color.

I greatly appreciate this information. Thank you so much.
