The lower you put the pH the faster the pH rises (because of faster outgassing of carbon dioxide)
The more you aerate (move) the water (by water features, spillovers, fountains, splashing kids, negative edged, SWCGs, etc.) the faster the pH rises (because of faster outgassing of carbon dioxide)
Thank you for the replies! I am looking at the tips page, and how to effectively lower alkalinity, and it specifies aerating to LOWER the alkalinity. Do I aerate to lower or will that increase alkalinity?

Also, I have some leftover sodium bisulfate. Can I use that to lower pH/alkalinity? It would save me some $$, and it would use up product that was already here.
