GLB SuperSonic – 1lb Pool Shock Treatment
Fast-Acting Pool Shock for Crystal-Clear Water
Cloudy water, stubborn algae, and unpleasant odors can take the fun out of your pool. When your regular sanitizer needs backup, GLB SuperSonic – 1lb delivers. This powerful pool shock treatment is designed to quickly restore water clarity, eliminate organic contaminants, and leave your pool sparkling clean and safe for swimming.
Packaged in a convenient 1lb bag, GLB SuperSonic is easy to handle and dose, making it ideal for weekly maintenance or as a quick fix after heavy pool use, storms, or algae outbreaks.
Why Shock Your Pool?
Even with regular chlorine use, contaminants build up over time. Swimmers introduce sweat, body oils, cosmetics, and waste. Environmental factors like pollen, rain, and debris add even more demand on your sanitizer.
When chlorine becomes “combined” with these contaminants, it forms chloramines, which reduce effectiveness and cause that strong “chlorine smell.” Shocking breaks down chloramines and restores chlorine efficiency.
Shocking is also the most effective way to:
-
Kill algae growth
-
Clear cloudy or hazy water
-
Eliminate strong odors
-
Prepare your pool for heavy use

How GLB SuperSonic Works
SuperSonic is a calcium hypochlorite (cal-hypo) shock. Once added to pool water, it releases a high dose of free chlorine that quickly oxidizes contaminants and kills algae. The powerful surge restores sanitizer levels and brings water back into balance fast.
Because it’s a granular shock, it should be broadcast evenly across the pool surface with the pump running for best distribution.
Best Times to Use SuperSonic
-
Weekly Maintenance – Prevent cloudy water and keep chlorine working efficiently.
-
After Heavy Use – Following pool parties or holidays with lots of swimmers.
-
Post-Storm Cleanup – Rain and debris can disrupt water chemistry.
-
Algae Outbreaks – When green, black, or mustard algae appear.
-
Seasonal Opening & Closing – Start and end the season with clean, sanitized water.
Application & Directions
-
Test Water First – Balance pH (7.2–7.6) and alkalinity before shocking.
-
Pre-Dissolve (Optional) – In cooler water, dissolve shock in a bucket before adding.
-
Add to Pool – Broadcast evenly across the deep end with pump running.
-
Circulate Water – Allow 4–8 hours of circulation for even distribution.
-
Wait Before Swimming – Do not swim until chlorine drops back to 1–3 ppm.
⚠️ Important: Never mix SuperSonic with other pool chemicals. Always add shock directly to water, not the other way around.
