The lowest on mine is 6.8 so I will get it to 7.0. I ordered the 2 bottles of that metal calcium stuff. It says it'll be here by the 29th or 31st. So I want to leave the pump running 24/7 until then. I know I need to scrub and vacuum daily also, which I do. Do I want to add any clarifies or flocs? Or just keep filtering? I appreciate your help so much. I have learned a lot from reading posts in the forums and am learning more now
