I'm having some issues testing CYA with my new TF-100 test kit (first time using). Am I looking for the dot to completely disappear (i.e. no trace of a dot no matter how faint) or am I looking for the dot to change to a lighter shade of gray?
My other test results are:
Salt - 2430
FC - 4.5
CC - 0.5
TC - 5.0
TA - 130
CH - 150
CYA - ~23 if you wait until you can't see any trace of the dot
