My Hayward generator can generate 1.47 pounds of chlorine per day. I assume this is 24 hours at 100%. How can this be translated to ppm at various % and run time? I thought I saw something on the app but now can't find it.

Here are the steps in the PoolMath app:

IMG_1111.jpgSelect "Effects of Adding"

IMG_1112.jpgUnder "Chemical Additions" pull down the first list box and set it to "SWG." Then click the magnifying glass icon next to "24 Hr SWG Output."

IMG_1110.jpgSelect your Hayward model from the list.
