    Cloudy Water -- At my wits end!!

    I have had my pool open for 4 weeks already. When we uncovered it, the water was brown (not sure why). Shocked and treated and now the pool water is pretty well balance and not discolored in any way. If it werent cloudy things would be perfect. We have tried shock, floc, Pool First Aid, filtering non-stop, and blind vacuuming.. etc etc etc... To no avail, we are still cloudy. I can see maybe 15 inches into the pool but thats about it. Here are the particulars:

    Pool Size: 22,000 gals. (In Ground)
    Type of Filter: Sand (with 5 year old sand, Time to change it?)
    Type of Pool: Inground, Vinyl Liner
    Pump Size: 1.5 H.P.
    FC - 2.0
    CC - 2.0
    pH - 7.4
    TA - 130
    CH - 200

    Is that CC measurement right? If so you need to shock (the process, not the product).

    What is your CYA? This is critical information in order to know what FC level you should maintain.

    I suspect that your FC is too low for your CYA even for maintenance level let alone shock level.

    How do you chlorinate your pool?

    Free chlorine - 2
    Total Chlorine - 2
    CYA - 40
    We use the Hayward chlorinator and granular shock

    With CYA at 40, you want to keep FC between 3 and 7 and never below 3.

    You will gets lots of opinions on the sand. Some will say change it every 5 or 6 years, and others say their sand is 20+ years old and have no intention of changing it!

    You might want to try cleaning it:

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Cleaning the sand bed or inspecting the sand bed may help ........maybe/maybe not.

    What will almost always clear your pool is to shock it properly throught the Shock Process described in "How to Shock Your Pool" up in Pool School. Read that, ask questions if you need to, and perform that process. YOur pool will clear.
