Fast-Dissolving Dichlor Chlorine That Sanitizes and Shocks Spa and Hot Tub Water
Leisure Time® Spa 56 Chlorinating Granules are a concentrated dichlor chlorine made specifically for spas and hot tubs. These fast-acting granules sanitize and shock hot water in one product, helping keep your spa clean, clear, and ready to enjoy.
The 2 lb container is a convenient, easy-to-store size for routine hot tub care. It's a good fit for smaller spas, new chlorine users, or anyone who wants a dependable granular sanitizer on hand without committing to a larger supply.
Sanitizes and Shocks in One Product
Spa 56 does two jobs. A small routine dose maintains a 2 to 3 ppm chlorine residual that controls bacteria and organic contaminants between soaks. A larger dose superchlorinates the water to break down odors, oils, and buildup and to help control algae.
Using the same granules for both steps keeps your hot tub routine simple, with no separate chlorine shock to keep track of.
Concentrated Dichlor Formulated for Hot Water
Spa 56 contains 99% sodium dichloro-s-triazinetrione dihydrate with 56% available chlorine. The fast-dissolving granules are formulated for hot water and are virtually pH neutral, so they sanitize without throwing off your water balance.
Just ½ ounce treats 500 gallons, making Spa 56 an efficient way to keep a chlorine spa in range.
A Compact Size for Everyday Spa Care
The 2 lb container holds about 32 ounces of granules, or roughly 64 half-ounce doses for a 500-gallon spa. Actual use depends on spa size, bather load, water temperature, and how often you superchlorinate.
It stores easily with your other spa supplies and is ideal if you're trying chlorine for the first time or caring for a smaller hot tub.

Important Compatibility and Safety Notes
Compatibility and Water Balance
Spa 56 is a chlorine sanitizer for chlorine-based spa and hot tub programs. Do not use it in a spa treated with bromine or a biguanide (non-chlorine) system. Because dichlor is stabilized, it adds cyanuric acid (CYA) to the water over time. Keep CYA at or below 100 ppm, and drain and refill your spa every 30 to 90 days, or more often with heavy use.
Safety First
Spa 56 is a strong oxidizer. Always add the product to water, never water to the product. Do not mix it with other chemicals, including other spa or pool treatment products, and never pre-mix it in a bucket. Keep the container tightly closed and dry, use only a clean, dry scoop, and store it in a cool, dry, well-ventilated area away from heat, flame, and children. Wear eye protection and gloves, and always read and follow the full label directions and warnings.
