You should wait one hour per pound of shock product added, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool. As a reminder, you want your pH to be between 7.2 and 7.8ppm and your free available chlorine to be 1-4ppm for safe swimming.

What happens if you swim in a shocked pool?

If you enter the pool immediately following a chlorine pool shock treatment, you are risking as little as skin and eye irritation and as much as fatality. Shocking your swimming pool is necessary, but take caution when doing so.

How soon after shocking a pool can I swim?

After Shocking Your Pool

It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours. It is always best to test first!
