I'm just curious if anyone could give me some average numbers on their FC PPM loss over a day. Preferably some southerners, our pool hits 90 degrees during the day lately with alot of sunshine. I just got done clearing the pool from a dash of algea, I cought it quickly and got on top of it fast. Yesterday I went without the swg during the day for 12hrs to start bringing the FC down and I lost 5ppm, just wondering if this is about right.
