I use the API calcium test kit and the directions say to shake after each drop. Does anyone know if adding more than one drop at a time will affect the test results? For example, if I know my Ca should be about 400mg which is 20 drops, could I add 15 drops at one time just to get close to 20? Also, can you do the same thing with the alkalinity test? Thanks for the help!

that's how I normally do it. try both ways see if reading changes by more than kit variance.

I never was able to get a satisfactory reading from the Ca test. Ammonia, Nitrite, Nitrate, Alk and Copper work pretty well though.
I am much happier with Salifert now for Ca and Mg.
