Chem Geek recommended aerating and following directions from Pool Doc in "Lowering Swimming Pool Alkalinity -- A Step by Step Guide" which includes the following,


"If your CA / TA level is not what you need to be, then you keep adding acid, so the pH will stay down:
. . . so the lost carbonic acid will keep being replaced with newly converted carbonic acid
. . . so the CO2 will keep gassing off
. . . so the CA will keep dropping.

When your CA gets where you want it, just stop adding acid, but keep aerating till the pH returns to the 'normal' level.

My PH levels have never dropped during the time I have been reducing the TA and CH levels. This may be where I am getting off track. Pool Doc and Chem Geek say to keep aerating, and my understanding was that doing so during SWCG operation would help GAS OFF the CO2 created by the electrolysis process to help prevent the PH rising. Don't at some point I need to add enough acid to drop my PH to near the lowest level of my test kit recommended in "Lowering Swimming Pool Alkalinity -- A Step by Step Guide" ?
