    Cloudy water dilemma.

    Opened to a green mess once again, shocked till holding overnight.
    I still can't see the bottom due to white cloudy water, have put a nylon over skim basket and with a few kids swimming in it, noticed more stuff being caught but still can't see bottom.

    Numbers are..
    FC 3.5
    CC .5
    TC 4
    PH 7.8
    TA 90
    CYA 40

    Only lost 1.5 PPM overnight which has been my norm over the past few seasons, have been running the pump 24/7 for 2 weeks now.
    Just changed sand in filter last season and pump seems to be working fine.
    Should I take it back up to shock level to get rid of the .5 CC?
    Add DE to the filter to help with the cloudiness?

    The usual rules of thumb have you shock until CC is .5 or less, lose no more than 1ppm overnight, and the water is clear. You've got one out of three. It can take sand filters a while to clear up cloudiness, a 1/2 lb of DE can help with that.

    If I don't see an improvement by this Friday, I am going to drain and refill, getting tired of not being able to see the bottom.

    The Chlorine/CYA chart says with CYA 40 your shock level is FC 16, are you maintaining that level? Did you try adding some DE? These are the quickest steps to clearing up the pool.

    Also noticed your pH is toward the high end, try reducing from 7.8 to 7.5 and see if that helps.

    Ph is down to 7.5 this morning and I have had .5 cc or less since the start of this.
    Haven't been able to get out to get any DE, but at this point dumping and filling will be just as easy.
