Cloudy pool water after shocking is normal for 24 hours.

Usually. Dead algae and minerals getting kicked up make the water hazy. Give it a day with the filter running, and it clears up on its own.

The shock oxidizes stuff in the water — algae, bacteria, organic gunk. Those dead particles float around until your filter catches them. That’s the cloudiness. If your pH or alkalinity is high, the cloud can hang around longer because calcium precipitates out.

Fix: run your filter 24 hours straight. Backwash if your pressure goes up. Test pH and alkalinity — keep pH between 7.2 and 7.6, alkalinity 80–120 ppm. If it’s still cloudy after 48 hours, add a pool clarifier or a flocculant. But most of the time, patience and filtration do the job.

You shocked it. Now let the filter do its thing.
