    Re: Help

    Lowering TA does not raise pH.

    See this article from Pool School:

    Re: Help

    Lower PH to 7 using muratic acid (acid lowers PH and TA), then aerate your water to raise PH to around 7.6 without raising TA. Repeat, until you reach your target TA

    Re: Help

    You need to aerate to get pH up. Then add acid to lower pH to 7.2, then do this process over and over. There's an article in pool school as well.

    How did you get your test results? If they're accurate, you've got other things to worry about before getting TA in line.

    Re: Help

    Not sure why I overlooked the obvious

    You need to be focusing on your very high CYA level and the fact that you have high CC before worrying about TA.

    Re: Help

    CYA of 100 is too high and should be lowered via water replacment first. Also CC is way too high and should be addressed by completing the shock process described in pool school.

    Edit...Jbizzle beat me to it!

    Re: Help

    So the CYA requires a 50 % water change?

    I put a whole bucket of the solid conditioner in guess i screwed up big time !!!
    So thats making my TA hard to control ???

    Thats the only way to lower cya. You should put your pool specs in your sig.

    Re: Help

    Done .. Thanks !! Guess i gotta rent that honda pump i used last time !!!
    And buy some salt..
    I did a absorbic acid treatment to get rid of some brownish stains , pool looks good but last month stains came back after shocking. Right now i have the metal sequestered with jacks magic purple stuff, would a complete drain and fill get all the metal out for good ?

    What size was the bucket of cya?

    Yes, if of course it is metal free water Also, as you add make-up water, if that has metals you levels will slowly creep up (though it will take a long time). Beware that completly draining a pool is risky if you have a high ground water since that can "pop" your pool up.

    Re: Help

    What was your CYA reading prior to adding the container of CYA? CYA does not make TA hard to control, however High TA fill water can present a challenge.

    Re: Help

    Must have had some cya in there already. 4lbs wouldnt have been enough to raise it to 100 in 30,000 gallons of water unless there was some in there already. Should've tested before adding.

    Thats what I'm thinking too. That 4 lbs should have only raised the pool by 16 ppm cya.
