Ok, so I have read a the threads on too much copper in pool. I'll take care of this in another thread.

What kind of effect should I expect with the FC between 3 and 6 ppm? Will it cause the liner life to go way down? Will it cause skin irritations? Will it cause hair to become "straw-like"? These are issues I want to avoid. And what level does my CYA need to be if I want to keep the FC down between 2 and 3 ppm?

Also, how long does it take for the FC levels to come back down to the normal levels after I shock? When is it safe to swim again?

Thanks a bunch for your answers!
