How long do I have to stay out of my pool after treating it with YELLOW OUT®?
YELLOW OUT® dissolves immediately, is neither an algaecide nor an herbicide and as such has no poisons in it. However, because of the concentration of chlorine in your water after treatment, we recommend you stay out of your pool as long as you normally do after you shock or super-chlorinate your pool. How long you wait to swim after super-chlorination is a matter of personal choice, but we recommend waiting at least 8 hours.
After the chlorine has dissolved completely, when the pool is clear and visibility is good, you may swim at your discretion.
