    Passed overnight test but...

    ...water is still cloudy blue. Should I drop it back down to normal chlorine levels and wait? My numbers look fine (TA might be a little high), sand got changed about 2 weeks ago.

    FC: 20
    TC: 20.5
    pH: 7.8
    TA: 120
    CYA: 75

    I am ASSUMING my CYA is still 75, haven't checked it in a few days. I've added/backwashed since my last test. So do I keep shock level or let it level out? I can see about 8in down and that's it. Maybe 3 steps on my ladder?

    You should continue at shock level until either the water is clear or you have passed to overnight FC loss test.

    CYA doesn't change very quickly unless you are doing a large water replacement. I wouldn't worry about it right now.

    You are keeping your filter running 24/7 right? That will speed up getting rid of the cloudiness.

    You said you passed the overnite test----------then let the FC drop off and keep circulating/backwashing.

    Re: Passed overnight test but...

    New numbers this morning have me a bit frustrated. The dog DID get in the pool last night. Obviously the 90 degree weather made her a bit too hot! Anyway...

    FC 11
    CC 1.5
    TC 12.5
    pH 7.5
    TA 120
    CYA 60

    Since my CC is up from .5 to 1.5 do I shock again or leave it alone?? I assume it is because my dog went for a swim. I HOPE it's not because the algae decided to come rearing its ugly head back.

    You should shock it again. Anytime the CC is higher than .5 we advise you shock.

    Q: Are you covering the pool at all?
    Q: Is it possible you errored on the CC test?

    I do not cover it, no. My cover was lost in a winter storm and I do not have the funds to replace it right now. I just did a recheck and since last post my FC has dropped to 8 and CC is at 1. I will shock again. I don't mind shocking, just want my clear pool.

    poolmomma,

    Don't be in a rush to pass that overnight test. I wouldn't run that test again until your water looks crystal clear to you. Keep your FC at shcok level until that happens.
