5 Reasons Your Pool Is Cloudy After Shocking

Dead algae from shocking turns water milky Shocking oxidizes organic matter, and dead algae particles float in the water, causing cloudiness. This is normal and usually clears in a day or two with the pump running.

High calcium hardness can cause precipitation If your calcium hardness is high, shock can make it precipitate out as white cloudiness. This also resolves with time and filtration.

Run the pump continuously and clean the filter Keep the pump running 24/7 until the water clears. Backwash or clean the filter every few hours if pressure rises.

Use a clarifier or flocculant if it persists after two days Add a pool clarifier or flocculant according to the bottle instructions. Floc will sink particles to the floor, then vacuum to waste.

Don’t add more shock until it clears Adding more shock will make cloudiness worse. Test your water; if calcium is high, switch to a non-calcium shock like lithium or a chlorine-free oxidizer next time.
