Is the pool full or empty? Depends how long they were in there. If it was just overnight, no big dal. If it was a week, I would shock the pool. Pool Masters.
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.
Shock your pool at sundown and you can swim in it the next morning.
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.
Once chlorine level drops to 5 ppm or below, it is safe to swim.
Yes you can add shock solution to your swimming pool after or at the same time as a clarifyer. You should not swim in your pool for at 4 hours after shocking it.
1/2 a bag will cover up to 5,000 gal & is still safe for a 3800 gal pool; use 1/2 a bag about every 4 to 6 days. Shock will clear the green but may not clear the cloudiness if you wait too long, but the water should still be safe to swim in; have your water tested by your pool professional at least once a week, it's usually free.

Pool shock typically contains a higher concentration of chlorine compared to regular pool chlorine products.
