Long story short: pump sprang a leak just before 10 day vacation. Pool store repaired it while we were gone, but left it off and thus the water was green when we returned. I'm in the process of returning it to blue (shocking with bleach) and vacuuming up all the pollen that fell in drifts on the bottom ... we're on day three of shock regimen, so I know I just have to be patient.
My question is this: my 4-year-old doesn't understand why she can't swim, and I'd like to give her an honest answer. She sticks her legs in the water while I'm vacuuming and doesn't have any ill effects. I tell her that she'll get itchy all over if she swims in a green pool, but since her legs don't itch I don't know if that's actually true.
Also: is there any safe time to swim before the water is crystal clear? I'm thinking no, but thought I'd ask on behalf of a little swimmer!
