Cloudy pool after shocking is normal — just run the filter.

It’s usually dead algae or calcium settling.

When you shock a pool, you’re basically nuking everything organic in the water. That dead stuff turns into fine particles that float around until your filter catches them. If your filter runs long enough, they get trapped and the water clears. Same deal if you used a granular shock — those undissolved bits can settle on the bottom and cloud things up until they dissolve or get vacuumed.

The fix is boring: run your filter 24/7 until it clears, brush the walls and floor daily, and test your pH and chlorine. High pH after shock can also cause cloudiness (calcium scaling). If that’s the case, bring pH down to 7.2–7.4 with muriatic acid or a pH decreaser.

Patience is the main ingredient here. Give it 24–48 hours. If it’s still foggy after that, check your filter pressure and clean the cartridge or backwash. Also make sure your chlorine level isn’t way too high — a lot of fresh shock will make water temporarily hazy on its own.

You didn’t mess up. The cloud means the shock is working.
