    FC and CC Readings

    I'm testing using the test kit recommended by TFP. When I test the FC, do I wait until the water turns clear permanently or turns clear the first time? When the water initially turns clear, I turn to record the # of drops, it's back to pink. I wind up adding 3-5 more drops before it turns permanently clear. I think this has an effect on the CC readings (the next step).

    I have added 23 gal. 8.25% bleach the past six days.

    What is the rec'd CC level; it doesn't show in the Pool Calculator?

    Re: FC and CC Readings

    What are you getting for CC? Is this with the extra 3-5 drops during the FC portion of the test, or without?

    What is your cya level?
    What was it when you closed last year?
    What was it when you opened this year?

    There isn't one since you want CC<0.5 ppm.
