    Need help with TA test in TF-100

    Here are my other test results:
    pH 7.5
    FC 18
    CC .5
    CH 280
    CYA 80

    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.

    There are no dumb questions.

    I would wait until your FC drops and then retest. No worries!

    I cannot explain the color changes but you can be pretty comfortable you TA is not 40.

    I don't know if you meant nine more drops for a total of 13 or nine total drops but, in either case, T/A of of 90 or 130 makes sense.

    A total of 9 drops turns the water yellow...thank you AGAIN Dave and FPMom. I'll retest after my FC drops and won't worry, thanks to you guys. It's so nice to have y'all around to rescue me!!

    Then your TA is 90 ppm.
