    Higher TA value might due to the pH upon circulation

    This article will walk you through things. Be sure you put the right pool surface and so on into the Pool Calculator.
    I don't mean to hijack, but I have a question for your Richard320.

    You say the pH will most likely rise due to circulation with a TA level of 80. Could I ask you what a higher TA value (say, 150) might due to the pH upon circulation? That's my situation--low pH, high TA. Going to do more aeration tonight with husband gets home from work with the sump-pump.

    The higher your TA, the faster your pH will rise with aeration.

    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!

    If your TA is high, then your pH shouldn't stay low or be dropping over time unless there is some acid source, such as using Trichlor pucks or even Dichlor as a source of chlorine.

    Thanks for the replies. I am using only bleach (now for the last 5 days; started with Trichlor and Dichlor 8 days ago) for chlorine, and am now aerating, so hoping that pH will increase soon.
