Ph and alkalinity

[whitemok]

My pH is 7.5.
My chlorine is 2.
My calcium is 200.
My alkalinity is 40.

How do I raise the alkalinity to 80 without raising the pH using bicarbonate?

Baking Soda has very little immediate effect on pH. High TA will push ph up over time.

Plug your numbers into poolmath and see what the dose of Baking Soda should be. Then scroll down to Effects of Adding Chemicals and enter that amount there. It should give you a close approximation of what the baking soda will do to the pH.

Yes I was wondering how I can calculate the dosage needed for alkalinity and also see the effects on the pH as well. How do I do that?

Pool School - PoolMath explains how to use http://www.troublefreepool.com/calc.html Take the time to read the article, don't just rush off to use poolmath. You might miss some of the features otherwise.
