Red Sea foundation pro calcium test kit help

[sergio706]

Im on the last step to getting calcium number but I’m not sure what number to read. Do I read number where the water level is at or do I read the black part of the syringe?

I've always read the plunger level. I believe the liquid in the tip accounts for the air gap within the syringe.
