Hi everyone,
The Salifert test kits for Ca, Mg, KH/Alk, and Phosphate instruct
My question is, am I supposed to take the reading the first time I notice a drop of reagent changing the color of the water in the test tube, once half the water in the test tube changes color, or should I keep adding reagent until all of the water in the test tube has changed color and then take the reading?
Thanks!

It is not the case that all drops will be ineffective until suddenly one drop changes the color of all of the water in the test tube. Rather, you'll add drop after drop and suddenly you'll notice that one drop changes the color of a little of the water in the test tube. As you continue to add drops, more water changes color.
