I added the recommended amount of liquid chlorine last night and today FC=1 and CC=1. From what I read and have always done.....I should be shocking after sun goes down to prevent loss. While I am shocking this pool, should I be doing this during the day as well or stick to evening. Where is all this chlorine going that I am dumping in? Is it killing and evaporating?

You must maintain your shock level all the time and never let it go below, day or night.
I my case I decided to shock 3 PPM higher than my chart said this way when I was busy, (work, family) and didn't tend to the pool I wouldn't fall below my shock # and my pool cleared up within a couple of days.

You need to maintain shock level as often as possible until you pass the OCLT. Testing and adjusting once an hour is recommended.
Once CC is .5 or less, how long do you keep the water at a shock level? Do you just let it fall to FC level recommended (in my case FC level recommended is 5-7 for CYA of 60)?

Read the last two lines of dave's sig line on the post above yours. That is when you are finished shocking.

Once you've passed all 3 critereia, you just let the FC drift back down to the normal range.
Ok....Another question about shock and FC/CC. My FC level is 5 this morning and when I went to bed it was 17. CC is .5 My water is crystal clear. Am I done shocking when I can maintain FC level of my recommended 5-7 without losing more than 1 ppm overnight or when I can maintain shock level of 18 without losing more than 1 ppm overnight. My hunch is that I am not done. We have an automatic cover (dark navy blue)...is it ok to cover after adding the bleach to keep the sunlight off the pool? Or can I just add enough each day to stay in that 5-7 range? Still learning....
brh, you should still be shocking 
The <1 ppm loss at night is at all levels.
The down side to covering is the CC can not be burned off, so I would leave the cover off.
Ohhh, and try and keep it above you shock level at all times (best you can). If you need to overshoot the FC a bit (but not up to mustard shock level) to stay above you shock level, I would.

brh, there's two things that will make your FC level go away like that. One is sunlight. The other is organics. Since you said it dropped 12ppm's in the dark, that means something is eating your chlorine and you still need to be shocking.brh said:
