I'm trying to use the PoolMath app to determine how much liquid chlorine I've added over a given interval of time. I thought that I used to be able to retrieve such data but now the "Summary" page doesn't seem to list ounces/gallons but instead shows PPM. It looks like the app recently updated to a new version. Does anybody know if I can utilize PoolMath to show how many Gallons of LC I've added over the last month?
