    Fighting the Green monster - quick question

    Fighting a green swamp in a 13,000g outdoor pool.

    I've read the tutorial a few times but I have just a couple of questions.

    Here were my results 2 days ago right after I shocked it:

    FC 25
    Cc 3
    TA 20
    PH 7.0
    CYA - I guess there is none cause my test filled the whole tube and the dot was still visible.
    So I threw in a couple of tablet/stabilizers to help.

    Anyway, the Next morning:
    FCC 18
    CC 1.5


    Around 3 in the Afternoon same day...
    FC 11
    CC 0

    I just dumped another bottle of chlorine in.

    So here's my question. The pool is now fully blue but not clear at all.
    I'm running the filter 24/7.

    The pool school tutorial states that this shocking process should continue until a few things occur.
    One of those things is that CC has to get to 0.

    It's only been one day and my CC is now 0.
    Am I done? If not, How long do I continue?

    Thank you!

    Not done. Sorry.

    You've only passed one of the three tests. You stlll need to pass the overnight test and the water has to be clear.

    You also ought to add more CYA. You'll lose far too much of that precious chlorine to the sun otherwise. 30 is a good target.

    Go study the articles in Pool School a little more. As you do the work, and keep testing, it will start to make sense and you won't feel like so much.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
