"Abbreviated" calcium hardness test ration help please

[calstar]

Is this the right amount chems/proceedure to use for the CH test with the TF-100 test kit?

fill cylinder to 10ml mark with pool water
add 10 drops R-0010
add 3 drops R-0011L
add R-0012 1 drop at a time until color changes to blue, multiply x10 for CH

thanks, Brian

title should'a been ratio, not ration(but I guess it does help ration the chems)

If you use 10ml, then you multiply by 25ppm

Like Jason said, multiply drops by 25. I find it easier to read with 5 drops of R-0011. And blue means sky blue, not lavendar. If you don't have a speedstir, expect it to take close to 10 minutes if you have real hard water. You need to mix it well, really really well. When I switched to using the speedstor, my CH readings dropped by about 200. Same water.
