Information

Sanitizing with Chlorine

Chlorine is one of the most common and effective sanitizers used in hot tubs to keep the water clean, clear, and safe for use. It works by releasing hypochlorous acid, a powerful agent that neutralizes bacteria, viruses, and other contaminants while maintaining water clarity.

Types of Chlorine Granules

The main forms of chlorine used in hot tubs include:

• Sodium Dichloroisocyanurate (SDIC): A fast-dissolving option ideal for regular maintenance.

• Calcium Hypochlorite: A strong sanitizer often used for periodic deep cleaning or shock treatments.

• Lithium Hypochlorite: A high-quality, quick-dissolving chlorine suitable for smaller spas and soft water conditions.

Proper Use and Maintenance

For best results, always add the correct dosage of chlorine granules according to your spa’s capacity and manufacturer’s instructions. Regular water testing ensures balanced sanitizer levels and optimal water quality. Consistent application helps prevent cloudy water, scaling, or irritation — ensuring a safe and enjoyable hot tub experience every time.
