    I bought one of these tests today and would like to ask the following questions. When one adds the chemical it must turn from blue to yellow.

    The instructions say that one drop equals to 1DKH but then later says that each drop is equal to 0.5DKH. My test changed after 19 drops, so either my KH is way out of whack, perfect or those Italians cannot write a decent instruction manual.

    What's the right way to interpret the test result?

    it has different regents, one is for a "coarse" reading and the other a "fine", if you put 19 drops, must be the 0.5 drops, therefore dkh = 19*0.5 = 9.5?

    Tony on the Elos kh kit each drop = 0.5 deg kh so you must take the amount of drops and devide it by 2. They are quite accurate have tested with a TM kit and Salifert kit to compair and they are very close together

    Some interesting reviews on salt and test kits. For those that have not seen it already.
