I'm not sure what you are asking, but to use those solutions, fill the drop checker bubble about half full of the 4dKH solution, add 2-3 drops of the pH test solution, and you are ready. The drop checker should be very blue before you put it in the tank. If it is any other color, use your regular pH test kit low range solution instead of the pH test solution you received.
Did that solution turn a strong blue color before you put it in the tank? All drop checkers react fastest if you fill the bulb so the liquid in them has the maximum of surface area, which means about half full.
