Ok, I'm kind of confused about the last step. See the pics below. Instructions say to pull the syringe until the lower black part is at 1.0 ml. There is an air bubble and then the liquid actually starts at .825 ml. I dripped it until the color changed, and the black part was at .15 ml. This means I have 1485 mg?? Or am I doing it wrong? My CA is 420, kh 7.
