HTH 52036R Pool Care Shock Advanced is a fast-dissolving 4-in-1 pool shock that sanitizes, clears cloudy water, reduces chlorine odor and irritation, and controls algae for weekly maintenance.

Keep your pool water sparkling with a shock formulated to act quickly and without adding cyanuric acid (CYA). Designed around calcium hypochlorite chemistry, this six-pack supports routine weekly treatment to tackle the majority of common pool water issues within 24 hours. It’s compatible with all pool types, including vinyl-lined and saltwater systems, and pairs well with routine testing to maintain balanced water chemistry.

How fast will I notice clearer water after using this shock?

Most backyard pools see visible improvement within a day when dosed according to label directions. The fast-dissolving particles disperse quickly so sanitizer levels rise promptly and contaminants are oxidized.

• Works to resolve up to 90% of typical pool water problems within 24 hours
• Fast-dissolving formula shortens treatment time compared with slower compounds
• Visible clarity returns as combined organics and microbes are broken down

Will this work in my saltwater or vinyl-lined pool?

Yes — the HTH 52036R formula is safe for vinyl-lined pools and compatible with saltwater pools. Because it uses a calcium hypochlorite base and does not add stabilizer (CYA), it avoids overstabilization concerns that can affect chlorine performance.

• Safe for vinyl liners when used at recommended dosages
• Compatible with saltwater systems and typical pool equipment
• Does not contribute cyanuric acid, preventing chlorine lock over time

How do I use it and how often should I shock my pool?

Follow the label for dosage based on pool volume and current water condition; routine weekly shocking is common for maintenance. For optimal results, test water chemistry twice weekly with test strips and adjust chlorine and pH before treating.

• Apply according to the product label and pool volume guidelines
• Test water with HTH 6-Way Test Strips twice weekly for best outcomes
• Maintain balanced pH and free chlorine for effective sanitation

Does this reduce chlorine smell and swimmer irritation?

The multi-action formula is designed to oxidize the organic compounds that cause strong chlorine odors and irritation. While it helps reduce those causes, maintaining proper chlorine levels and pool balance is also important for comfort.

• Oxidizes combined chlorine and organic contaminants that contribute to odor
• Reduces factors that can irritate eyes and skin when used as part of regular maintenance
• Works best with routine testing and balanced pool chemistry

Who is this for: HTH 52036R Pool Care Shock Advanced is aimed at homeowners and pool caretakers seeking a dependable weekly shock for clean, clear water. It suits owners of vinyl-lined pools, saltwater systems, and conventional chlorine pools who want a fast-acting, CYA-free option for tackling algae, bacteria, and cloudiness.
