I've learned and incredible amount from this forum, and in searches I've gotten the exact answers I've wanted regarding chlorine, how it enters the pool, and how it works.
However, in my searching, I haven't seen anything about TA. If this has been covered already, please give me the link. If not, here's my question for the chemistry experts (cough cough, chemgeek, cough)....
I understand the process for reducing TA (aerate, add acid, repeat). Can someone spell out the chemical reaction, and explain why this works? I had an AHA! moment a few months ago perusing the forums here. Last summer, I was constantly adding acid but also adding "Alkalinity Up" on the direction of the pool store. Turns out, when I opened the pool, the eyeball return was pointed up, and I was aerating the pool without even knowing it. Now I know for next year, but I was curious about the nitty gritty of the process.
Thanks in advance.
