    High Phosphates

    Just got back from the pool store with a phosphate reading of

    my other numbers are
    FC 4.11
    CC - 0
    TC 4.11
    CYA 35
    alk 100
    hardness 230

    my options are to do nothing, as my water appears clear and no signs of algae. or I could throw in some
    phos out, which involves the pool getting cloudy for 4 days and lots of vacumning etc.

    skip it! Unless you level is way-super-higher than what was being discussed, someone (waterbear? JasonLion?) has said the high-phos angle is just the latest and greatest way for the pool store to separate your money from your wallet!

    see the last post on this thread.

    "Shock" is a process, not a product!

    You may want to verify your Ph level. The pool store has it at 7.9 which is a little could use one of the calculator programs to find out how much acid you need to bring it down.

    I think I have the JasonLion calc linked in my signature...check it out>>>

    Combining both posts above is the best advice I think you'll get. Ignore the phos and lower the pH to around 7.4

    Thanks for the advice, I will bring down the pH today, just need to get to the backyard with the acid.
    I do notice that this year my pool is taking a lot more acid than it did last year. Anyways, thanks for the advice. The pool
    store did say I could just leave it alone as nothing may happen, so they are not completely trying to hose me.
