I've got the TF-Pro Salt kit and am wondering about how big a scoop of R-0870 I should use for the test. I have tried leveling the scoop and also a larger scoop added to the 10 ml mark go pool water in the included graduated cylinder and get very different FC results.

Can someone please tell me the correct amount of R-0870 powder to add or direct me to a good demo video?

Thanks!
