the "timing is everything and i'm an idiot" question

I was under the impression that you don't want to place a cover on a pool that you are shocking - it will wear out your cover faster

that's a good point..i do leave it on when i add smaller amounts of bleach but i haven't with "bulk"..i think i'll leave it off until i'm done shocking and get to normal levels..thanks!
