If your pH is over 7.2, aeration should not have an effect.
TECHNICALLY, aeration does lower TA, but practically it doesn't.
TA rises and falls with pH, generally, but when we aerate it doesn't. pH rises, but TA stays the same.
My understanding is that the amount it actually lowers TA is offset by TA rising with the rise in pH. The net effect is zero change in TA.
So while the chemists will tell you that aeration actually lowers TA, when we use it to raise pH, we don't see TA change and therefore say it's the only way to raise pH (after we lower it to lower TA) without raising TA again.
Since this process only works when pH is at 7.2 or lower, it shouldn't affect your pool. Try keeping TA higher--say 125-130 at a normal pH--and see if your pH rises as fast.
