How long does it take acid to bring down PH? I added 3 cups last night but PH is still 8.2

What is your FC level? If it is above 10, you are probably getting a false high reading. Also, the typical drop based test does really measure above 8.2, so it is possible you are very high. My ph usually changes/stabilizes ~1 hour after adding the MA.
You should be able to retest and adjust pH within an hour.
As linen said, FC over 10 can skew the pH test for a false high reading.
What is your TA? And, do you use borates? If yes, what is borate level?

Results should be evident in one hour. Add 1 quart more in that pool to reduce pH from 8.2 down to 7.4 and retest in an hour or so....pump running. I assume your acid is 31.45%
