My Alkalinity is between 130 and 140 and my PH is 7.7, I want to lower my alkalinity. I am adding 65 oz of MA to get me down to 7.0 - 7.2. My question is how long do I wait before I turn my waterfall on to airate the pool to bring the PH back up? How long do you recommned airating the pool to bring it up? and how long before I can add another dose of MA to start the process over until I get my Alkalinity around 90.
