    Newbie - cya and shocking

    Hi everyone,

    Brand new to the board. I moved into a new home with a 20,000 gallon in ground pool. I had almost all the water drained and put in fresh city water.
    I got the recommended tf100 tester last weekend. I basically had no chlorine, no cya and normal levels of pH.

    I did pool math and added the recommended volume of stabilizer in socks. It's been over a week, and it's still dissolving.

    My question is, can I shock now assuming the cya had reached the level pool math had calculated? Or do I have to wait longer?

    Pool is a little greenish tinge now. Will post pictures soon.

    Can I start the recommended shock level based off pool math now?

    SLAM your pool for the level of CYA you have added-or at least how much has dissolved!. Welcome to the forum.

    Yes. You can assume the CYA is in your pool and SLAM at that value.
