I am quite curious after reading a few posts about the effects of Aeration, pH and lowering TA.
I used to have a saltwater aquarium and there could be such a range in pH just by having the aquarium close to a fresh air source, i.e. an open window. Fresh air takes the pH up and when windows are closed during the night the pH trends back down. (Along with a few other influencing factors as well)
So I have been reading that to lower Alkalinity, reduce the pH low to 7.0-7.2 and aerate the water to bring the pH back up. So my question is "Once you end aeration at a pH of 7.6 or so, wont the pH just go back down to the value from the Muriatic Acid addition?
