When pool water turns cloudy, smells like chlorine, or starts showing early signs of algae, a fast and decisive shock treatment makes all the difference. GLB SuperSonic 1lb Pool Shock is a powerful calcium hypochlorite (cal-hypo) shock designed to quickly restore water clarity, eliminate chloramines, and bring sanitizer levels back under control.

This single-dose, easy-to-use shock treatment dissolves quickly and goes to work immediately, making it ideal for weekly maintenance, post-storm cleanup, heavy swimmer use, or when water chemistry needs a rapid reset. SuperSonic delivers strong oxidation without adding stabilizer, helping prevent long-term chemical buildup while keeping water clean and comfortable.

Why Pool Shocking Matters

Regular shocking is essential for maintaining safe, clear, and odor-free pool water:

• Breaks down chloramines that cause eye irritation and strong chlorine smells

• Kills algae spores before they bloom

• Restores sanitizer effectiveness after heavy use

• Improves overall water clarity and sparkle

Using a reliable cal-hypo shock like GLB SuperSonic helps prevent small problems from turning into expensive water issues.

Fast-Acting Calcium Hypochlorite Formula

GLB SuperSonic uses calcium hypochlorite to deliver a strong, immediate chlorine boost. Unlike stabilized shocks, it does not add cyanuric acid to the water, making it a smart choice for pools that already have adequate stabilizer levels.

Once applied, SuperSonic rapidly oxidizes organic contaminants, clears cloudy water, and frees up chlorine so it can work more efficiently.

Ideal for Weekly Maintenance and Water Recovery

This 1lb bag is pre-measured for convenience, allowing pool owners and service professionals to dose accurately without guesswork. It’s well-suited for routine weekly shocking as well as corrective treatments when water conditions decline.

SuperSonic is compatible with most traditional chlorine pools and works effectively after rain, pool parties, or periods of high heat.

Easy Application with Professional Results

GLB SuperSonic dissolves quickly when broadcast into the pool or pre-dissolved according to label instructions. Its fast action means less downtime and quicker return to clear, swimmable water when used properly.

As with all cal-hypo products, proper handling and storage are important to maintain safety and performance.
