Borax or no?

[Kimmmg2003]

TA 90
ph 7.2
CYA 30 just enough to reach 60
CH 100
FC 7
Temp 69-70 today
Should I add borax to bring up ph with the TA at 90 or only use aereation? Can use the jet pointed up. Bought the borax but scared to mess up.

Your pH is fine! Usually the SWG causes some rise in pH. Mine likes to stay around 7.7-7.8, works fine for me.

You have a vinyl pool..no need to sweat pH as long as its in the 7s.
