To raise both PH and Alkalinity at the same time, use Arm & Hammer Baking Soda. You can get it in 4 pound boxes at the grocery store and 12 pound bags at Sam's Club, Costco, etc. There is a dosage chart on the box. As for what your levels should be...I have a chart at home that I made up using various information from this board & Pool Solutions (PoolDoc runs both sites). But, I'm not home right now...I'm at work.
