    Sodium bicarbonate, baking soda, raises TA a lot and PH just a tiny amount. It isn't a very good way to raise PH.

    Both sodium carbonate, also called soda ash, and borax are good ways to raise PH.

    Two ounces? I'm assuming that a typo since 2 oz of baking soda added to 8,000 gallons of water will only raises the TA by 1.1 ppm

    Well according to PoolMath for a 8,000 gallon pool, to take TA from 70 ppm to 100 ppm you need 56 oz (weight ) of baking soda.

    That's good because a ton will increase your TA by 17,846 ppm where a pound will increase it by 9 ppm. PoolMath
