Maintain a sparkling, healthy pool with high-quality pool shock and shock treatments. Shock is an essential chemical that is designed to quickly eliminate bacteria, algae, and contaminants, restoring chlorine levels, and keeping your swimming pool clean and clear all season long. Winter pool shock treatments are concentrated oxidizers that break down combined chlorine and organic waste, helping prevent cloudy water and pool water quality.
Using shock during your winter closing prevents staining, algae growth, and cloudy water, reducing the need for extensive cleaning when reopening in the spring. Our selection includes fast-dissolving chlorine-based and non-chlorine shock options, making it easy to raise sanitizer levels quickly and effectively before installing your winter cover.
