API Calcium test kit help

[D_Reep1106]

Hey guys I just got my tank back from a buddy and was testing my water and cant find the instructions for my API Calcium test kit. I have the bottles but no instructions. Anyone know them off the top of their heads or can shoot me a pic of them would be awesome!!

thanks in advance!

Fill the tube to the line after rinsing it.
10 drops of bottle 1. Shake well.
Add drops from bottle 2 until you reach the end point of titration. Each drop is 20 ppm Ca.

When the color goes from pink to purple, you are only 1-2 drops away from the endpoint.

Also, shake the heck out of bottle 2 for 30 seconds before titration. It needs to be "well mixed".

I haven't seen the need to shake it that long. But it won't hurt. Not like the nitrate bottle #2. I've always gotten consistent results and comparable to other test kits.
