LEISURE TIME Spa 56 Chlorinating Granules 4 lb Bucket — Fast‑Dissolving 56% Chlorine for Spas & Hot Tubs

Leisure Time Spa 56 is a fast-dissolving granular chlorine sanitizer formulated for regular spa maintenance or as a powerful shock to keep hot tub water clean and clear.

Designed specifically for spas, hot tubs, and jacuzzis, Spa 56 delivers 56% available chlorine in a sodium dichloro base that dissolves quickly without adding calcium or leaving gritty residue. It eliminates organic contaminants introduced by bathers and helps control algae while working within standard chlorine sanitizing systems. Use it as a regular sanitizer to maintain free chlorine between 2–3 ppm or as a shock treatment when levels need a quick boost. Always balance pH and total alkalinity for optimal performance and follow safe handling instructions on the label.

How should I apply Leisure Time Spa 56 to my hot tub?

Broadcast the granules directly into the spa water while the jets are running to help the product disperse and dissolve evenly. There's no need to pre-dissolve—Spa 56 is formulated to dissolve quickly in spa temperatures and will begin sanitizing immediately.

• Add with jets on to promote distribution and dissolution.
• Target free chlorine levels at 2–3 ppm for routine maintenance.
• Wait at least 5 minutes after adding before soaking to allow initial mixing.
• Wear gloves and follow label directions; store granules in a cool, dry place.

Can Spa 56 be used as both a routine sanitizer and a shock treatment?

Yes—Spa 56 is versatile and can be used daily to maintain proper chlorine levels or in larger amounts as a shock to rapidly raise chlorine and address cloudy or contaminated water. Adjust dosages according to label guidelines and test water chemistry before and after treatment to ensure safe soak conditions.

• Routine: small, regular additions to sustain 2–3 ppm free chlorine.
• Shock: larger dose when contamination, heavy use, or cloudy water occurs.
• Test pH and alkalinity first; chlorine is most effective when water is balanced.
• Avoid combining with incompatible chemicals; follow wait times before re-entry.

Will Spa 56 leave residue or affect my spa’s plumbing and surface?

Spa 56 is formulated to dissolve without depositing calcium or gritty residue, so it is safe for typical spa surfaces and circulation systems when used as directed. Using the correct dose and maintaining balanced water chemistry reduces risk of buildup and helps preserve equipment longevity.

• Quick-dissolving granules minimize residue on shell and filters.
• Does not add calcium, reducing scale risk compared with some alternatives.
• Compatible with standard chlorine sanitizing systems; follow manufacturer guidance.
• Regular use and proper filtration help prevent debris and organic buildup.

How do I get the best results from this chlorine product?

Consistent water testing and balance are the keys to effectiveness—keep pH and total alkalinity in recommended ranges so chlorine works efficiently. Combine routine Spa 56 dosing with proper filtration, periodic filter cleaning, and shock treatments when needed for a complete maintenance routine.

• Test free chlorine, pH, and alkalinity regularly (test strips or kits).
• Balance pH and alkalinity to maximize sanitizer effectiveness.
• Run filtration daily and clean or replace filters per schedule.
• Use as routine sanitizer and occasional shock to control heavy loads.
