    cya was too high, emptied half of pool and are the numbers now

    filled pool on Sunday and this is my first test results taken:

    PH 6.8
    CC 0
    CYA 40
    TA 40

    Couldn't test FC or CC because the powder didn't change the color of the pool water sample. the powder looks darker than I remember it so I guess it went to the bad somehow since last season. Last season was my first year with a pool and I don't have a good memory so can somebody please confirm what I should set the numbers in pool math to and how much of each chemical I need to add right now. Thanks!!!

    have you put any chlorine in the pool since you filled it? I would imagine the powder is good. It says good for a LONG time.

    If there is 0 chlorine, then there will not be any pink when you put the powder in.

    The powder is fine. That just means you FC is 0ppm.

    You can set the parameters at the bottom of PoolMath and it will list suggested targets for you to enter.

    Really all you need to do is raise the pH and TA a little and get some chlorine in the water.
    You could raise the pH with soda ash which would also help the TA and then use baking soda to get the TA up to around 70ppm.
