Sirona Chlorinating Granules Spa Sanitizer 4 lb

Sirona™ Chlorinating Granules are a fast-dissolving, spa-specific chlorine sanitizer designed to keep hot tub water clean, clear, and safe for soaking. Formulated specifically for the higher temperatures and smaller water volumes of spas and hot tubs, these granules provide reliable daily sanitation while also acting as an effective shock treatment.

Unlike pool chlorine, Sirona Chlorinating Granules dissolve quickly without leaving residue, allowing chlorine levels to rise evenly and predictably. This helps prevent cloudy water, strong chlorine odors, and irritation caused by inconsistent sanitizer levels. The 4 lb size is ideal for regular spa owners who prefer precise dosing and consistent water care.

This product is intended for chlorine-based spa systems and is compatible with Sirona’s full line of spa balancers and maintenance products.

Why It Matters

Proper spa sanitation is critical for both water clarity and bather safety.

Why this matters:

• Provides fast-acting chlorine sanitation for spas and hot tubs

• Destroys bacteria, algae, and organic contaminants

• Doubles as a shock treatment to burn off oils and waste

• Dissolves quickly for even chlorine distribution

• Designed specifically for hot water environments

Designed for Spa & Hot Tub Use

Spas operate at much higher temperatures than pools, which accelerates sanitizer consumption. Sirona Chlorinating Granules are formulated to perform reliably in hot water without overstabilizing or creating harsh chemical spikes.

This makes them ideal for routine maintenance, post-soak sanitation, or weekly shocking as part of a balanced spa care routine.

Clean Water Without Harsh Side Effects

The controlled-dissolve granular formula helps minimize strong chlorine odors and reduces the risk of bleaching spa surfaces when used as directed. When paired with proper pH and alkalinity balance, Sirona Chlorinating Granules maintain comfortable, crystal-clear water.

Compatible with Sirona Spa Care Systems

Sirona Chlorinating Granules integrate seamlessly with Sirona Spa Up, Spa Down, clarifiers, enzymes, and water conditioners. Using a matched system helps simplify water chemistry and reduces guesswork.
