So sloppy of me - I'm sorry. Yes you're right I meant: "Your CC of 0.6ppm" and "your CC is less than 0.5ppm (10ml sample - 0.2ppm CC for 25 ml sample)" Thanks for understanding what I meant not what I wrote.

I will be shocking my pool this evening. I still have it covered as we are having storms again today. Do I need to wait till evening even with it covered or can I go ahead and shock now since the pool won't be used and won't be receiving sun?
Start the shocking process as soon as you can. You probably don't want to leave the pool covered as shocking can produce noxious gasses that may be unable to escape from the cover - these gasses may also damage the cover.

After shocking and I test in the morning if chl is below the 10ppm, do I add more at that moment or wait until evening again?
Test and dose as often as you can regardless of time of day.

I will keep swimmers out of the pool until I get this chl level adjusted.
I don't think you need to stay out of the pool. Some of the disinfection byproducts (DBPs) can be irritating so watch your swimmers closely. The DBPs can also be smelly (smells like "chlorine"). Please review Ben's Best Guess Chart.

Also if I add it right after the low reading, is there a time frame I should wait before I test again?
Let it mix for and hour or two.

...I am seeing some algae and plan on vacuuming it out today before I shock tonight. Explains why my CC is up there!
Sure does. I'd shock first then vacuum to be sure you kill the algae you stir up.
