I'm attempting to follow step 1 of waterbear's fabulous how-to on adding borates to pool, but I cannot get the TA down to the target range of 70-80. I did drop initially from about 140 down to 120, but i'm stuck there.
It took me a day to realize that I had to add more acid to "fuel" the aeration (and again, thank you, waterbear, for the amazing explanation on the carbonate ions and how the aeration process lowers TA in TA--What is it really?. This same process occurs in our lungs to maintain our acid-base balance in our bodies - when acid levels get too high, our lungs "blow off" CO2 to bring pH up in the blood.
So, now, I'm wondering, to get from 120 to 70-80, how much acid will be required, and how often will I need to resupply the acid?? I have to work today, so I can't be checking chemistry all day, but the weekend's coming (woo-hoo!)
