    cloudy

    Good morning everyone,

    Just need some encouragement.
    I passed the OCLT 2 consecutive nights in a row and pool is clear. I ran a back wash Sunday. Monday pool is cloudy again. Clear from above and clear in the water for about 10 ft but from one end to another not clear. We have had some windy days and a lot of debris in the pool. I don't image that would cause cloudiness.

    History - Just got the CYA to 35 last week. Have been using DE to help with filtration but that was back washed out last week.

    FC - 5.5
    TA - 120
    PH - 7.2
    CH - 110
    CYA - 35/40

    any ideas??

    Please and thank you

    Re: cloudy

    Hi. Are you running the pump continuously? Only until it clears up. If the water isn't circulating it's not being cleaned. I find that if I turn cloudy that I need to run a lot longer than I normally do to clear it otherwise I can't catch up. Doesn't seem to be a chlorine issue so it would seem it needs to be filtered to get everything out. btw, I'm more expert on making my pool cloudy than on clearing it up so others may have better advice.

    You mention passing an OCLT & clear water, were your CC's 0.5ppm or less for those 2 consecutive days also?

    Could you also post a current CC level?

    If this were my pool I would do another OCLT. If your filter was adequate up to, & during the SLAM why wouldn't it be now?

    I would do another OCLT to make sure it is not something organic. The remedy for cloudy water is almost always chlorine.

    Re: cloudy

    Agreed raise FC to 9 or so, so you can still test PH, for a few days and see how the Overnight Chlorine Loss Test looks.

    Re: cloudy

    OCLT was .5 first day and second day 0.
    Current CC - 5.5

    I was going to do another slam tonight and see what happens. Sand filter had a deep cleanse mid season last year.

    thanks everyone for the help.

    technically it appears that you have passed all 3 criteria to complete a SLAM but if it was me I would go one more day and do another OCLT tonight to be safe. What's one more day after all of that hard work? Do a good scrub of all nooks and crannies also, (ladder, lights, etc.)

    Re: cloudy

    Have you inspected behind the light, ladder, behind the stairs? Any water features (rock, waterfall, slide, etc) where algae could be hiding?

    When you say clear, can you tell whether the screws on the main drain are phillips or flat head? If no main drain, did you do the quarter test... put a quarter in the deep end and tell if it is heads or tails?

    When you did the OCLT, was the pump running all night?

    Re: cloudy

    I only have one ladder and nothing there.

    I can see the screws on the main drain.

    Pump has been running 24 hours since Wednesday. Was going to leave it on all weekend as well.
