Thank you for the reply, Watermom. There are no iron stains inside my toilet tanks. Also, I do not recall my chlorine levels ever dropping low after adding in the bleach - I am taking measurements every morning and evening (the only time they were low was in in very beginning/first day or so when I was first adding the bleach to get the chlorine levels up).

Quick question - how long will it take for the chlorine level to drop after shocking it up so high? Can my kids (ages 6 and 8) still swim in the pool tomorrow if I shock it tonight? Just want to be safe with my kids and understand the expected timeline before they can swim after shocking the water.

Thanks!

Kevin
