I recently lowered my PH to 7.0 in order to remove white spot calcium build up on pool which I understand can take quite a while. I discovered small brown spots on seating ledge of pool and did the Vitamin C test which took them right off. My question is do I need to raise my PH back up to do the AA treatment or can I leave it at 7.0 so I don't have to just lower it again? Thanks as always!
