Hi everybody!! (Hi doctor Nick!)
Anyway, I have a question about TA and it's purpose. So, I am catching up on all the post that I missed while I slept (am I the only one that sleeps on this website?), and I saw a post by chem geek:
Total Alkalinity (TA) Myths
Myth: Increasing TA lowers rate of pH rise
from this post: http://www.troublefreepools.com/viewtop ... highlight=
I thought that TA slowed pH rise by acting as a buffer. I did some looking and saw this by Jasonlion (thanks for poolcalc):
Total alkalinity indicates the water's ability to buffer PH changes. Buffering means you need to use a larger quantity of a chemical to change the PH. At low TA levels the PH tends to swing around wildly. At high TA levels the PH tends to drift up slowly, or even quickly in extreme cases.
from this sticky: http://www.troublefreepools.com/about2375.html
I know both people are very knowledgeable, and I don't doubt either (they are both WAY smarter that I), but I am confused now.
I guess my question is what does TA do?
