    TA / pH chart to quickly choose the correct adjustment

    I think I can use some help here. I've begun to create a chart that can quickly show me what action to take when making pool chemistry adjustments, but I have three blanks. Can you fill them in for me?

    pH high and TA high: add muriatic acid

    pH high and TA good:

    pH high and TA low:

    pH good and TA high: bubble air

    pH good and TA low: add baking soda

    pH low and TA high:

    pH low and TA good: add borax

    pH low and TA low: add washing soda

    pH high and TA high: add muriatic acid

    pH high and TA good: add muriatic to lower pH; Bring TA back up with baking soda

    pH high and TA low: bring TA up over target; Lower pH and TA comes with it

    pH good and TA high: bubble air] Use acid and aeration per Pool School article

    pH good and TA low: add baking soda

    pH low and TA high: add 20 Mule Team Borax

    pH low and TA good: add borax

    pH low and TA low: add washing soda
