Question on refilling pool

[Jimh64]

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.
