OK so I have a API calcium test kit, i have to mix 2 reageants the first one is 10 drops and the second 1 drop shake one drop shake.... you get the picture, until it changes from pink to blue. So it says to keep track of all the drops I put in to determine the ca++ level. So my question is do I add all the drops together? Or is the first 10 drops excluded, and I count just the second reageant drops? Thanks in advance guy!!! and sorry for the stupid question.:nerd:
