Hi all,

I do have a question regarding chlorine and how it interacts with CYA.

What is it with "unprotected" chlorine that allows it to be used up by a warm sunny day?

Also...

What is the interaction between CYA and chlorine that seems to protect and stabilize the chlorine in water?


When CYA levels raise, why is it that additional amounts of chlorine are needed to reach a disinfecting levels.

Does the CYA "lock up" partial amounts of chlorine...so that they aren't available for either disinfecting...or even some of the ill effects of higher chlorine levels. As if all the chlorine is not available for use at higher CYA levels?

thanks,
dan
