I think all you need to observe is when the color change. I got this elos test kit too and i think it is more works than Salifert

Is it the "new elos Mg" with 4 bottles? If so you have to add 3ml h20 + 9 drops of "A" + small scoop of "B" + ?c, count drops of "C" the do the same with agent "D" and then subtract "C" from "D" to give you a number something close to 27-28 multiply by 50 to get your MG level, I believe but im not at home to check the exact instructions. The first solution should go redish orange and the second will be dark green and they are noticeable changes.

Edit: I think is 9 drops not 7, i think 7 drops is for Ca
