Poolife Rapid Shock - Fast-Dissolving, CYA-Free Calcium Hypochlorite Pool Shock (1 lb x 24) for Algae, Bacteria & Contaminants

Fast, Clear Water Starts Here

Poolife Rapid Shock is a calcium hypochlorite pool shock formulated to tackle algae, bacteria, and surface contaminants with speed. When added properly, it dissolves quickly and leaves the water feeling more buoyant and looking visibly clearer. With a routine weekly dose, you can support balanced sanitization and smoother pool maintenance, especially after heavy use, storms, or seasonal changes.

Designed to be convenient and effective, this CYA-free formula helps keep chlorine working where you need it most, without contributing to stabilizer buildup. It’s suitable for both above-ground and in-ground pools, and it works across multiple finishes like vinyl, plaster, and fiberglass, making it a versatile option for many backyards.

How to Use for Best Results

• Broadcast 9–16 oz per 10,000 gallons over a wide area in the deepest part of the pool, with the filter running in the evening.
• If granules settle, brush the area to disperse and avoid residue on the pool floor.
• Maintain water balance by keeping pH in the 7.2–7.6 range and follow the Shock Treatment directions on the label.
• Test available chlorine with a reliable test kit and repeat the treatment as needed to sustain 5–10 ppm for about a week.
• Open water balance and stabilizer considerations are important; adjust as needed for weather, swimmer load, and pool volume.

Whether you’re opening a pool for the season or managing ongoing maintenance, Poolife Rapid Shock provides a straightforward option to restore clarity and confidence in your water. While results can vary with pool usage and environmental factors, many users report quicker chlorine rebound and a more transparent appearance after treatment.
