I have a 24' x 52" AGP, approximately 12,600 gallons. My CYA is steady at 40, and I lose about 2~3ppm of chlorine every day.

My pool gets full sun from dawn until about 30 minutes before dusk. I'm also in Alabama where we have a lot of high temperatures and high humidity. I try to swim nearly every day, my wife doesn't swim quite as often as I do.
