Need to increase TA and have some xtra chems to use up. I have sodium bicarb from the pool store (="alkalinity up") which i assume is the same as baking soda. But i also have a bag of a bioguard product that is called total alkalinity increaser. It says it. Contains 100% sodium hydrogen carbonate. I just want to be sure this is the correct stuff before i throw it in the pool. It seems to be dosed the same as the alkalinity up.
