    Question on refilling pool

    I had to put a new liner in my pool (boy was that a project!) I was wondering if I have to shock my pool if it is not green? I know I need to add cya and bleach to bring my chlorine up, but if it is clear I should not have to shock do I?

    Thanks!

    If you have a test kit with FAS-DPD chlorine test you can run an over night chlorine loss test. That test is most accurate at shock levels but is ok to run at non-shock levels for a quick test.

    The longer the pool water sat without chlorine the more you are at risk for something growing.

    I just filled it up overnight with city water. I do have the test kit recommended on here, so I guess I will bring my chlorine levels up, and then test them over night after I get some CYA in the pool.

    Thansk!

    With a new, clean liner and city water, I wouldn't bother with the shock process. Just keep close watch on FC, because it will disappear fast without the CYA sunscreen effect.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
