swimming guidelines

After shocking your pool, you should wait anywhere from 8 to 24 hours before swimming, depending on the shock type and water temperature. Calcium hypochlorite and lithium hypochlorite require closer to 24 hours, while non-chlorine shock permits you to swim sooner, sometimes within an hour.

Always test chlorine and pH levels first to verify they’re safe. Following these guidelines protects your skin and health, and there’s more to learn about how different shocks affect timing and safety.
