Need some guidance on getting ph up.

7.0 is not too crazy low. Do you have any way to aerate the water? Generate some bubbles and get air moving around? That will do it naturally. If that doesn't work or you can't aerate, use the Poolmath calculator to increase only the minimal amount of borax required to get you to about 7.2-7.4. PH usually increases on its own quite rapidly.
