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.

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.


Why Using Dichlor Shock Matters

Not all shock products behave the same in pool water. Stabilized dichlor offers predictable results for routine sanitation.

Why it matters:

  • Raises free chlorine quickly

  • Helps clear cloudy water

  • Kills algae and bacteria effectively

  • Protects chlorine from sunlight burn-off


Ideal for Routine Shocking & Maintenance

GLB Granular Dichlor Shock is commonly used for:

  • Weekly maintenance shocking

  • Clearing mild algae blooms

  • Restoring sanitizer levels after heavy use

  • Pools exposed to intense sunlight

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.
