Deep chemistry question here:
Lets say your pH is 7.5 and your TA is 100. If you have a SWG, the pH is always rising up due to Hydrogen gas production (and then gassing off) with SWG. So, you always add HCL to the pool 1 or 2 times a week.
I would think this would drive down the TA in a predictable fashion. However, TA (or bicarb as I think of it) seems to be stable for long periods of time.
So question one is: why?
Question two is: why do you have to drive the pH down to 7.0 to get the TA to get lower? I guess the answer depends on the first question as well.
Thanks!
