    Results after SLAM

    Ok, so I finally drifted down below 10FC this morning at 9:30am 5/7/2015. Here are my results and plan of action. I ran TA and CH twice to double check

    Readings after SLAM:
    TC: 5
    FC: 9.5
    CC: 0
    PH: 8.2
    TA: 280 took 28 drops to change to red
    CH: 550 turned a purple blue color after 23 drops
    CYA: 60 I added 9.4 ozs granular stabilizer via sock sitting in skimmer to get to 75(5/5 did not test today)

    Plan of attack
    Lower PH to 7.0 using 76 ozs of 14.5% muratic pool acid

    Please let me know if this is what you would do.

    I will wait for a reply before proceeding

    I am not going to worry about CH right now. I have hard water and a vinyl pool

    Re: Results after SLAM

    I assume the TC you reported was really from the yellow OTO test?
    In reality TC = FC + CC

    There is no need to lower the pH that far unless you are trying to actively lower your TA.

    Yes this is correct.

    I want my TA down too. It is too high

    Re: Results after SLAM

    That is lots of TA! Highest I've ever seen I think.

    Here is the process for Lowering Total Alkalinity. Just in case you haven't run across it.

    Re: Results after SLAM

    I agree. It was 80 or 90 before the SLAM. I saw the process of lower TA and PH with MA then aeration to bring PH back up. I am still not at home but will add 1/2 the 76 ozs of 14.5% MA and test again later to see where I am at Unless someone else's has a betterms suggestion.

    Re: Results after SLAM

    I seem to remember your test kit is pretty new. Did you read the instructions about wiping the dropper tip with a damp cloth? If not, that may be skewing your test to the high side.

    Re: Results after SLAM

    I will add to push the CH test until it is Blue. Sounds like you got close but not all the way to end point.

    Double check the TA as Duraleigh suggested, wiping the R0009 bottle tip. It shouldn't have moved like that. Do this re check before adding acid.

    As Blizzle mentions, your TC is 9.5 and I assume you meant the OTO reading as 5 which is high limit.

    Re: Results after SLAM

    I did make sure to wipe the tip after adding each drop. Yes my test is new. I will retest again when I get home and go from there. Yes the 5 is from OTO. I will retest PH, CH and TA when I get home.

    If you know the number, add or run your makeup water TA as well please.

    You mean test my tap water? I just got home but there was a power outage or surge when I was gone. Have the filter back on now and can run test in about 20 mins.

    Re: Results after SLAM

    Ok here is what I got

    2pm
    PH: 7.8-8.2 not quite 8.2 but higher than 7.8



    TA: 280 ( 28 drops of R 009 to turn from green to red. I would get hints of red on top but took 28 drops to turn all red. I wiped tip of 009 between each drop)

    Show water level


    Turned green


    Turned red



    CH: 400 did this 3 times took 25 drop of 012 to turn from red to blue
    Water level


    Red


    Blue


    Water from kitchen sink
    TA: 230 (23 drops)
    CH: 475

    At one point our well had to be shut off during slam and I used city water to fill pool when topping off after backwashing.

    So I think I should go with calling PH 8 and add 36 ozs of MA (14.5%)

    Opinions?

    Re: Results after SLAM

    Your fill water is like mine, and it's the culprit. If you push the pH to 7.2 every time and often, you will eventually push the TA down. in your pool, if you just manage the pH, you won't scale. You should see a fairly quick rise in pH with that TA though so just keep an eye on it.

    Your test end point colors look great BTW...good job.

    Glad I am not the only one. Figured pics may help.

    So I just added 36ozs. Do you think I should go ahead and add the other 36 ozs since my TA is so high or wait?

    Re: Results after SLAM

    want to confirm that MA does not lose its strength from what I have found on my search on here. Is this correct?

    Thanks. I added 36 ozs of MA pool math called for 72 ozs. Do you think I should go ahead and add the other 36ozs?
