Leisure Time Spa 56 5 lb | Chlorine Sanitizer

Leisure Time Spa 56 Chlorinating Granules are a concentrated, fast-dissolving granular chlorine sanitizer engineered specifically for spas and hot tubs. Active chemistry: 99% sodium dichloro-s-triazinetrione dihydrate (commonly called sodium dichlor), delivering 55% available chlorine — one of the highest concentrations available in a stabilized residential spa product. EPA-approved, hot-water optimized, and trusted for over 40 years as the foundation of Leisure Time's chlorine-based Simple Spa Care Program. Chlorine remains the most reliable sanitizer in the world for a reason. It kills bacteria, viruses, and pathogens within seconds of contact, breaks down quickly into harmless byproducts, and works across an enormous range of conditions. In a hot tub — where water temperatures favor microbial growth and bather load can spike sharply — having a fast-acting, predictable sanitizer matters more than in any other recreational water environment. Spa 56 is engineered to do exactly that. The dichlor chemistry dissolves cleanly in seconds with the jets running, brings residual chlorine into the ideal 2–3 ppm range within minutes, and includes a built-in stabilizer (cyanuric acid, formed during dissolution) that helps protect the chlorine from breakdown by UV light and high temperatures. A 5 lb bucket provides several months of routine sanitation for a typical residential spa, plus the headroom for periodic superchlorination every 2–4 weeks. Pro Tip: Add chlorine after a soak, not before. Bathers introduce the organic load (oils, sweat, lotion, skin cells) that chlorine is designed to oxidize — dosing afterward attacks that load while it's fresh and brings residual chlorine back up overnight, so the spa is ready and balanced for the next use. Dosing immediately before getting in often means soaking in chlorine that's too high while the contaminants you just added go to work consuming it. Brand Leisure Time®
