Hi, PoolMath says I need to add 111 oz by wt. of baking soda to raise TA from its current value of 80 to the target of 120 for a vinyl pool. This seems like a crazy amount -- about 7 lbs of baking soda! I'm leery to just dump that much into my pool. Might this adversely affect water quality, like taste or feel? Is there any reason to instead just raise the TA a little, with it ending up well below the recommended 120 level for vinyl pools?
