How long to get Borax PH increase test results?

Dog,

Download the bleachcalc in any of mwsmith2's post...you need it.

10 lbs of baking soda will raise your pool to around 60ppm....still 20ppm lower than the recommended level....I'm saying 10 because I still suspect that test result for Alk

I'll bet Carl's post of 1 lb was a typo.

Put 'em both directly into the skimmer, slowly, pump running.

Thx for the advice.

BleachCalc won't work on my Mac.

I'd start with 4# and see what happens. You can adjust upwards from there. Slapping 10# in there at once might not be a good idea!
