So if I understand you, my lowering pH with MA to 7, raising by aeration to 7.6, lowering by MA to 7, raising by aeration to 7.6, etc., actually might have done something other than waste time and MA. I don't feel so stupid, if so. I think though that Ben is saying that I need to KEEP my pH low for an extended period and not to aerate with the goal of raising pH all the way back up to 7.6 or higher before adding more MA. I will follow his instructions to the letter as my ultimate goal is to have a great pool with no unneccesary chemicals, to keep money in my pocket and not the pool store's, and to become "FormerBromineUser"!!!
