Can someone explain the different between the FC level and the warning on the bottle of bleach to not swim if bleach if more than 3ppm?
I am keeping my FC level at the recommend level and have not had any issues, but my husband is concerned with the bleach label stating that we should not swim if the bleach is higher than 3ppm.
Thank you.
