If PH is that low while you are shocking, I'd target 7.2 and go ahead and raise it with Borax.

I would try airation to raise PH without affecting TA.

update on my pool opening so far so good! i put the filter on a digital timer for run time of 6 hours 10am-4pm so it is filtered by time we get home from work is this enough run time to filter entire pool, i ordered a hayward aqua cleaner so we dont have to vac when we get home anymore so we can swin quicker, is there a set time i should run to filter pool completely?.....

fc 8
cc.5
ta 140
ch130
ph 7.8
cya 30-40 should i raise the cya to 50 range

Figuring out the ideal pump run time is complex. Your current 6 hour run time is probably about right. You can read How to Determine Pump Run Time in Pool School for suggestions on how to find a more ideal time.

Yes, you should raise CYA to 50, but there isn't any rush to do that right away.
