So my ph has been low dropping to 7.8 at night and maxing out around 7.9 during the day. Assumed it was just a lack of oxygen i tried opening the windows witch it helped jumped up to 8.2 during the day with the widows open. I ran a line outside for the skimmer. Witch its running 8 at night and 8.1 during the day. Would like it a touch higher and other suggestions to help get it up.
