how soon can you enter a pool after chlorine
After you shock the water, in your pool, you should wait at least 24 hours, before swimming. It is also very important to check the free chlorine level, after you shock the pool, and before you swim. Make certain that the free chlorine level, is within the acceptable parameters, only then is it safe to swim. It depends on the shock. I use lithium hypochlorite and I can swim after 15 minutes.
