### Fast-Dissolving Shock for Clear, Sanitized Pool Water

When pool water turns cloudy or sanitizer levels drop, fast action matters. **GLB Granular Dichlor Shock** is a **stabilized chlorine shock** designed to quickly raise free chlorine levels while protecting chlorine from rapid sunlight burn-off. This 1 lb bag dissolves rapidly, making it ideal for routine shocking, algae prevention, and restoring water clarity.

This product is part of our [**Shock & Oxidizer**](/collections/shocks-and-oxidizers "Stabilized Pool Shock") collection, designed for routine chlorine shocking, algae control, and fast sanitizer recovery in residential pools.

Dichlor shock is especially effective for regular maintenance and for pools that need quick sanitizer recovery without overstressing water balance.

### Stabilized Chlorine for Consistent Performance

Unlike unstabilized shock products, GLB Dichlor contains cyanuric acid (CYA), which helps shield chlorine from UV degradation. This allows chlorine to remain active longer, reducing waste and improving overall sanitation efficiency.

Because it dissolves quickly, it can be broadcast directly into the pool without pre-mixing when used as directed.

-   Raises free chlorine quickly
    
-   Helps clear cloudy water
    
-   Kills algae and bacteria effectively
    
-   Protects chlorine from sunlight burn-off

-   Weekly maintenance shocking

It is compatible with most residential swimming pools when used according to label directions.

### Application Notes

Add GLB Dichlor Shock directly to the pool with the pump running, preferably in the evening. Allow water to circulate thoroughly before swimming. Always test water chemistry before and after shocking to maintain proper balance and avoid over-stabilization.

Do not mix with other chemicals.
