If I'm using the alkalinity option in the calculator correctly, it says I need to add 18 pounds to get up to 115 ppm. That sounds like an AWFUL lot!!
you previusly posted that your ALK was 55 ppm. if it is still the same the directions on the Arm and Hammer baking soda box say you need to add 6 lbs per 10000 gal to get your ALK to the proper range. How big is your pool and what is your current ALk reading?
