Owned a pool at my prior home and used the Pool Math app to manage my levels. As I recall, the recommended FC level was 1 - 3 ppm. Fast forward a couple of years, we moved and built another pool. I loaded up the app again, but this time it is calling for 3 - 9 ppm for FC.
Am I mistaken or did the recommended FC level change?
