Shock your pool at sundown and you can swim in it the next morning.
actually there is a chemical called shock and swim made by HTH and you can get it at walmart. You can swim 2 hrs after you shock it. There are chemicals that if you shock in the evening you can swim by the next morning.
A good rule of thumb is to allow the water to clear up. After adding any kind of algaecide, I personally would wait at least 24 hrs. Once your chlorine level is at the acceptable range, 1.5-3.5ppm, you can swim.
No liquid shock is more concentrated
An algicide (or algaecide) is a substance which kills or inhibits the growth of algae.
Adding a great amount of salt in a single step is a salt shock.
most definitely
12-24 hours
If it's the stuff that HTH makes, the Shock-N-Swim stuff, you can get in right after shocking your pool. I just did it today. It's specially formulated to allow you to be able to swim immediately after shocking with 47% available chlorine.
You don't have to swim to be strong However if you have the choice of adding it to your regime of exercise it is very good.
Yes too much shock can damage your skin or hair or worse. I wouldn't reccommend it.
