Just got my pool up and running a few days ago and tested the PH, which was on the low end (about 7.2) so I added about 3.5 lbs of Borax yesterday into the skimmer. I checked the levels this morning and the PH went down a little. I've never had a this problem before so not sure what my next step is. My levels are below. Alkalinity is a bit low so maybe i add some baking soda first? I did have the heater running yesterday after putting the borax in but I'm not sure if that would be the cause. Any tips would be appreciated.
