POOLACC Pro-Grade Chlorine Pool Shock 6x1 lb — 68% Cal-Hypo Granular, Fast-Acting Chlorine Boost

POOLACC Pro-Grade Chlorine Pool Shock is a fast-acting, 68% calcium hypochlorite granular sanitizer sold as six 1-lb bags designed to quickly raise free chlorine and restore pool clarity.

This granular pool shock delivers a high available-chlorine formula for routine and corrective pool maintenance without adding cyanuric acid (CYA). It’s packaged as six convenient one-pound bags so you can dose small or large pools precisely. Use it to handle routine sanitization, treat cloudy water, and jump-start chlorine levels after heavy use or storms. Follow label directions and pre-dissolve when treating vinyl liners.

How fast will this shock raise my pool’s chlorine level?

POOLACC’s 68% cal-hypo formula is concentrated, so a single 1-lb bag delivers a significant free-chlorine boost. Expect a rapid increase in parts per million (ppm) when added correctly, allowing you to return to normal sanitizing levels faster than lower-strength shocks.

• One 1-lb bag treats 10,000 gallons to raise chlorine to approximately 5–10 ppm.
• Multiple bags can be combined proportionally for larger pools or stronger doses.
• Pre-dissolve granules in a bucket of water before adding to avoid bleaching liners.

Is this product safe for different types of pools and liners?

The formula works with in-ground, above-ground, vinyl-lined, and saltwater pools when used as directed. To protect liners and surfaces, avoid pouring undissolved granules directly against the pool wall and always dissolve or dilute before application.

• Compatible with vinyl-lined pools if pre-dissolved to prevent spotting.
• Suitable for saltwater pools as a non-stabilized chlorine source (no added CYA).
• Not formulated to add cyanuric acid, avoiding unintended CYA buildup.

How do I dose and apply the 6 x 1-lb bags correctly?

Each bag is sized for easy, repeatable dosing. For routine shock treatment, use one bag per 10,000 gallons; for heavier contamination or algae control, increase the number of bags proportionally and retest free chlorine before swimming.

• Standard dose: 1 bag per 10,000 gallons for a 5–10 ppm rise.
• Pre-dissolve in a plastic bucket of water and disperse evenly around the pool perimeter.
• Retest chlorine levels and wait until they return to recommended safe ranges before re-entry.

What maintenance tasks does this shock help with?

Beyond quickly elevating free chlorine, the product assists with routine sanitization, algae prevention, and reducing organic contaminants that cloud water. Because it doesn’t contain cyanuric acid, it won’t increase CYA levels that can reduce chlorine effectiveness over time.

• Kills bacteria and combats algae when used at recommended shock levels.
• Helps control chlorine odor and reduces eye or skin irritation caused by low sanitation.
• Restores clear water after heavy pool use, storms, or organic load spikes.

Who is this for? POOLACC Pro-Grade Chlorine Pool Shock is built for pool owners and service professionals who need a high-strength, no-CYA granular sanitizer that’s easy to measure and flexible to dose. It’s ideal for weekend pool keepers who want a compact, 1-lb bag option for accurate dosing, as well as maintenance teams managing multiple pools that require fast chlorine recovery and reliable results. Always follow safety and handling instructions on the label, store bags in a cool dry place, and use personal protective equipment when mixing or handling granules.
