    Re: Won't calculate

    Did you put in your pool's size in gallons, the current value in the left column and the desired value in the right column?

    Re: Won't calculate

    put your pool gallons in first, no commas! At the bottom of the calculator, select the option in the drop down for selecting target levels.

    In the left column of every category, the NOW column, put your current test result. When you TAB away from the field, or click to another field, that NOW column will be set.
    The target column is set already, bu may change depending on other entries. So when you add your current CYA reading in the now column for CYA, your target FC level will change appropiately. YOu can also manually change target levels if you need to get somewhere other that the standard targets (for raising FC to a SLAM level for example)

    Finally, pool math will instantly compare your NOW to your Target, and then show you in the text field to the right of the now/target, what you need to do to get from NOW to Target.
