I leaving tomorrow morning, I should be safe with my dad just adding granular chlorine for a week, correct??

Baking soda is not used to raise pH, it is used to raise alk. What is your alk now? 20 Mule Team Borax (laundry aisle at Walmart) is used to raise pH. Add a half a box slowly to the skimmer. Retest pH a couple hours later and add a little more if it is still below 7.6.
Did you add the rest of the CYA as advised?
I added the CYA as advised last night.
In the medical field a ph of 7.45 or higher is called alkalosis, that is where I figured raising the Ph is raising the alk...I'll go test that now
Total alkalitiy is 80ppm..how much borax???
Oh yeah borax is for the ph......sorry I'm already in "vacation mode"...ok some how is my alk???? Do I need anymore baking soda???

Your alk is good enough. If (after a while) you find you pH is moving too quickly, you may consider bumping up a little with baking soda.

What is the ingredient in your granular chlorine. Cal-hypo or dichlor? What is your pH?
