Where Has All The Chlorine Gone? Out by....

Okay, I give......CYA at "perfect level" doesn't tell me anything. There is no "perfect level" for CYA. The point I am trying to make is that if your CYA is on the low side, then it may very well be the sun causing the problem. If it's not on the low side, then it could be that you have an organic load that's still consuming your chlorine, or that your minimum chlorine level isn't high enough to compensate for your CYA level, which would explain why shocking didn't fix the problem. Also, without knowing your CYA level and the chlorine level to which you shocked, I have no idea whether your shocking the pool is effective. All of these things are possibilities, but without numbers it's all just a wild guess.
