Here are my other test results:
When trying to get my TA reading, the color changes from green to blue after 4 drops of R-0009,then to yellow after 9 drops. I see where the directions say that the test may go from blue to yellow in the presence of high chlorine as I have, but I didn't know if that meant green to blue to yellow. My TA was 100 a week ago. IF this is the dumbest question of the day, I'll wear a dunce cap and sit in a corner. My FC is high because I was shocking my pool and it's been cloudy here. As always, thanks for your help.
