When your pool water needs fast, decisive action, GLB Super Sonic – 5 lb delivers professional-grade shock treatment designed to restore clarity, destroy contaminants, and bring water chemistry back under control. This powerful calcium hypochlorite pool shock is formulated for rapid oxidation of organic waste, making it a trusted solution for pool owners and service professionals dealing with cloudy water, algae pressure, or heavy bather loads.

Unlike weak or diluted shocks that struggle to keep up, GLB Super Sonic works quickly to break down chloramines, eliminate bacteria, and boost free chlorine levels where they need to be. The result is cleaner, clearer, more sanitary pool water—without unnecessary additives or fillers.

High-Strength Shock for Fast Results

GLB Super Sonic is a high-available chlorine pool shock designed to address water problems efficiently. When added to the pool, it immediately begins oxidizing organic contaminants such as sweat, sunscreen, body oils, leaves, and algae spores. This rapid oxidation helps restore chlorine effectiveness and improves overall water quality.

This product is ideal when your pool shows signs of stress, including dull water, strong chlorine odors, or reduced sanitizer performance.

Why Shocking Your Pool Matters

Shocking your pool is essential for maintaining safe, clear water—especially during periods of heavy use or warm weather. Over time, contaminants bind with free chlorine, forming chloramines that reduce sanitation efficiency and cause irritation.

A proper shock treatment helps:

• Destroy chloramines that cause strong chlorine smell

• Eliminate bacteria, algae spores, and organic debris

• Restore free chlorine effectiveness

• Improve water clarity and sparkle

GLB Super Sonic is formulated to handle these issues quickly, helping prevent small problems from turning into major clean-ups.

Ideal for Routine & Corrective Shocking

GLB Super Sonic – 5 lb is versatile enough for both routine maintenance shocking and more aggressive corrective treatments. Whether you’re shocking weekly to maintain water quality or addressing a sudden water issue after a heatwave or pool party, this product delivers consistent, reliable performance.

Because it’s a calcium hypochlorite shock, it dissolves efficiently and starts working immediately when properly applied.

Compatible with Most Pool Types

This shock treatment is designed for chlorine-sanitized swimming pools, including:

• In-ground pools

• Above-ground pools

• Residential pools

• Commercial and service-maintained pools

It is not recommended for use in biguanide (PHMB) systems or bromine-only pools unless specifically directed by a pool professional.

Clean Water Without Unnecessary Additives

GLB Super Sonic is formulated to focus on what matters most: oxidation and sanitation. It does not contain stabilizer, which allows you to control cyanuric acid levels separately and avoid over-stabilization—a common issue with frequent shock use.

This makes it an excellent choice for pools where water balance and long-term chemistry control are a priority.

How and When to Use GLB Super Sonic

For best results, GLB Super Sonic should be applied according to pool size and water condition. Always pre-dissolve if recommended on the label and add during evening hours with the pump running.

Use GLB Super Sonic When:

• Water appears cloudy or dull

• There is a strong chlorine odor

• After heavy pool use or storms

• As part of a regular weekly maintenance routine

Following proper dosing instructions helps maximize effectiveness while protecting pool surfaces and equipment.
