Nicole,
I intentionally run a high CYA, as Watermom said earlier. In my 29K gallon pool, I keep my CYA at 80-90, because my pool is in full Louisiana sun from dawn to dusk. I also have a moderate to high bather load during the week, mostly young children. My pool goes through 2-3 gallons of 6% bleach weekly, on average. I also tend to shock it most weekends due to the young swimmer load, which requires 3-5 of the 1.3 gallon jugs from WalMart each time.
