OK, so i have stabilized my water and my CYA level is currently at somewhere between 40 and 50. My pool will get plenty of direct sunlight for most of the day during the summer. The pool calc says a range of 60 to 80 is good if you get a lot of direct sunlight.
How will I know if I need more stabilizer in my pool? Do I bump the CYA level up some if it's using too much chlorine on sunny days? What's the thing that lets you know you should be maintaining a higher level of CYA?
