OK -- the pH is near 8 but not a big deal right now. Wait until tomorrow some time and test again.
Prior to adding any acid, you should get your TA to 60 to 70 ppm using baking soda. Then test pH after it is well mixed and add acid to get the pH to 7,6.
Use the FC/CYA Chart to maintain your FC based on your CYA using liquid chlorine.
Okay, I will go pick up baking soda in the morning.
