POOLIFE Calcium Hypochlorite Pool Shock – 1 lb x12 Pre-Measured Bags, Fast‑Dissolving CYA‑Free

POOLIFE Rapid Shock is a fast-dissolving, CYA-free calcium hypochlorite pool shock sold in twelve pre-measured 1 lb bags to quickly restore chlorine levels and clear algae, bacteria, and contaminants. When storms, heavy bather loads, or early algae growth destabilize your pool water, this ready-to-use shock gets chlorine back to effective levels quickly without leaving residue. The CYA-free formulation avoids adding stabilizer, so you don’t increase combined chlorine lock and can keep sanitizer performance predictable. Each 1 lb bag is pre-portioned for easy weekly dosing whether you manage an above-ground or in-ground pool and works on vinyl, plaster, and fiberglass finishes.

How quickly will POOLIFE Rapid Shock clear cloudy water and algae?

Rapid Shock dissolves quickly and releases available chlorine fast, which helps oxidize contaminants and knock down visible algae within hours depending on severity. For routine weekly maintenance it keeps free chlorine in the ideal 5–10 ppm range; for heavy contamination you may need follow-up testing and additional treatment.

• Instant-dissolve calcium hypochlorite granules for fast action
• Pre-measured 1 lb bags reduce dosing guesswork
• Typical weekly dose: 9–16 oz per 10,000 gallons
• Works on vinyl, plaster, and fiberglass surfaces

What makes the CYA-free formula important for ongoing pool care?

Because POOLIFE Rapid Shock contains no cyanuric acid (CYA), it won’t increase stabilizer levels that can lead to chlorine lock over time. That means your free chlorine remains more effective at sanitizing, and you can manage sanitizer strength without constantly compensating for over-stabilization.

• No added stabilizer, so less long-term chlorine binding
• Helps maintain predictable free chlorine readings
• Compatible with standard chlorine testing and maintenance routines

How do I dose and use the pre-measured 1 lb bags safely?

Use one pre-measured bag per the recommended ounces for your pool size: add 9–16 ounces per 10,000 gallons weekly for maintenance, or follow higher-dose guidance for shock treatments. Pour granular shock directly into the deep end while the pump runs, avoid mixing with other chemicals, and wait the recommended return-to-swim time per local guidance and test results.

• Pre-portioned 1 lb bags simplify measuring and reduce spills
• Add directly to pool with pump and filter running
• Do not combine with other chemicals or acids
• Test free chlorine before allowing swimming

Will POOLIFE Rapid Shock work for both above-ground and in-ground pools?

Yes — the formula is suitable for both above-ground and in-ground pools and is safe for common finishes such as vinyl liners, plaster, and fiberglass when used as directed. It’s formulated to dissolve fully without leaving gritty residue that can settle on surfaces.

• Safe for vinyl, plaster, and fiberglass finishes
• Designed to dissolve fully for no visible residue
• Effective in salt pools that supplement chlorine, but test regularly

Who is this for: POOLIFE Rapid Shock is designed for pool owners, maintenance pros, and facility managers who want a dependable, fast-acting shock that’s easy to dose. It’s especially useful for people who prefer pre-measured convenience, those maintaining multiple pools, or anyone aiming to avoid CYA buildup while keeping water clear after heavy use or weather events. Always follow label instructions and local safety guidelines when handling and applying pool chemicals.
