I know I read the purpose for CYA a 100 times or more here. But I am still confused about it. I have a couple of questions I need explained to help me better understand the need for it.
What does it actually do for my Chlorine level?
I understand that it protects from chlorine loss due to UV sunlight, but why then is it the higher my cya is the higher my FC levels have to be?
In otherwords it seems to me that cya protects a certain amount of chlorine from sunlight consumption, but then I need more chlorine because the chlorine bound to the cya is usless??????
I know I'm missing something here, please shed some light on this for us more simple minded people.
