I actually have a related question to FCL and CYA levels. My chlorine readings drop like a brick in just a day or two. Ph and Alkalinity and other levels are within range. My CYA reading is only 26ppm. Should I significantly bump it up? Any downsides to a high CYA level? I always thought 20-40ppm was a good range? Maybe I'm wrong? Also the plaster is about 30 days old if that were to make a big difference. The pool gets a lot of sunlight as well (which would break down chlorine, correct?)
Thanks!!
