21,000 gal pool

Opened pool 2 weeks ago, I shocked w/ 6% bleach until help shock level over nite. I added 4lbs of cyanuric acid (cya level was 0). Currently, I am waiting to test cya level again to make sure it has all dissolved.

I was wanting to raise my pH and alk levels alittle. My alk dropped slightly from last year from 120 to 90. My pH normally runs about 7.6. The kids were swimming, and said the pool water burned their eyes alittle.

I can't remember, but it seems like I can add 1 product and raise both pH and alk at the same time, was it baking soda that will do that?? I would like to shoot for a pH of 7.6 and alk level of 100-120

Thanks for your help.

Blessings,
