Weighing 0.87 pounds per unit, this 13.3-ounce treatment uses a fast-acting, fast-dissolving Cal Hypo formula that delivers effective chlorination without adding cyanuric acid (CYA). That distinction matters: traditional chlorine products that contain CYA can lead to overstabilization — commonly called chlorine lock — which clouds water and reduces sanitizer effectiveness. Pool service technicians and knowledgeable DIYers reach for Cal Hypo shock specifically to avoid CYA buildup over the course of a season.\u003c\/p\u003e\n\u003cp\u003eThis shock treatment is suited for routine maintenance and recovery treatments across all residential pool types, including vinyl liner pools, fiberglass pools, and plaster pools. It will not fade vinyl liners. Typical applications include weekly oxidizing treatments, post-heavy-use super-chlorination, and algae remediation. Pool service professionals will find the 13.3-ounce per-unit size practical for single-pool treatment tasks without the handling complexity of larger bulk formats.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCal Hypo formula provides chlorination without adding cyanuric acid, preventing CYA buildup and chlorine lock\u003c\/li\u003e\n  \u003cli\u003eFast-acting and fast-dissolving for rapid chlorine level recovery\u003c\/li\u003e\n  \u003cli\u003eKills bacteria and algae to restore water clarity\u003c\/li\u003e\n  \u003cli\u003eSafe for all pool types including vinyl liner pools — will not cause liner fading\u003c\/li\u003e\n  \u003cli\u003eCompact 13.3-ounce unit size at 0.87 pounds for easy handling and single-application use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in all residential swimming pool types, including vinyl liner, fiberglass, and plaster pools.

Always power down circulation equipment if required by dosing instructions before adding shock directly to pool water. Wear appropriate PPE including gloves and eye protection when handling concentrated chlorine compounds. Never mix pool shock with other chemicals prior to application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActive Ingredient Type\u003c\/strong\u003e: Calcium Hypochlorite (Cal Hypo)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNet Weight\u003c\/strong\u003e: 13.3 oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.87 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHazardous Material\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HTH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HTH","offers":[{"title":"Default Title","offer_id":51721508651314,"sku":"52031","price":133.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe77afca0e0b2171dc8bae898df01eb7.jpg?v=1788578299","url":"https:\/\/voomisupply.com\/products\/hth-52031-pool-shock-treatment-13-3-oz-cal-hypo","provider":"Voomi Supply","version":"1.0","type":"link"}
