The use of a water sanitiser is essential to effectively eliminate bacteria, ensuring your spa remains clean and bacteria-free. Chlorine stands out as the preferred sanitiser for hot tubs and swim spas, providing a straightforward and safe way to maintain hygienic hot tub or swim spa water.
Opting for official Jacuzzi® Chlorine granules guarantees quality, meaning you'll require less product for the same level of sanitisation compared to other chlorine options.
How does chlorine function?
When you dissolve chlorine in hot tub water, it produces hypochlorous acid. This potent acid rapidly eliminates waterborne bacteria upon contact but gradually becomes less effective over time. Therefore, it's essential to regularly monitor the chemical levels in your hot tub or swim spa.
How do I determine the right amount of chlorine to use?
Aim to maintain a consistent chlorine level between 3 to 5mg/l. The frequency of adding chlorine depends on your usage patterns and bathing habits, whether it's a daily, bi-daily, or weekly routine. For every 1mg/l, add 2g per 1000 litres of water.
Pro Tip: 10ml is roughly equivalent to 10g.
*We highly recommend using test strips to evaluate sanitizer levels, pH levels, and Total Alkalinity (TA) for precise maintenance.
