api test kits

I lost my instructions for the API calcium and also Alkalinity tests. Anyone have a source for replacement? I looked at API online and nothing jumped out at me. They have an 800 number, but thought I'd post and see if that info was online anywhere...

This is from memory so....
Alk: Fill the vial up to the line. Add one drop at a time and gently shake until the color changes. Each drop = 1 dkh. 8 drops = 8 dkh.

Ca: Fill vial to the line, add 10 drops of #1. Shake. Add drops #2 and shake till color turns blue. 1 drop = 20 ppm. 20 drops = ca 400.

be careful of using old kits. The APIs have a short shelf life.

Thank you! It's less than one year old at this time, what's your recommended shelf life? I think API is all our LFS carries...
