All about me
These rapid dissolving Chlorine Granules are ideal to use as a sanitiser to disinfect your hot tub or spa daily. They help dissolve and release chlorine slowly, which kills any present bacteria and prevents algae from forming. It’s stabilised as well, so no chlorine is lost to sunlight exposure. They have minimal impact on pH levels, too, making the water safe for you and others to enjoy, and also come in a 5kg pack.

Pack size: 1kg
How to use
Aim to maintain a chlorine level of 3 to 5mg/l at all times. How frequently you add more chlorine will depend on your usage and bathing habits. It could be daily, every two to three days or weekly. For 1mg/l, add 2g per 1000 litres. Top tip: 10ml = approximately 10g
We advise to use test strips to test sanitiser levels, pH levels and Total Alkalinity (TA).
What is chlorine?
When you dissolve hot tub chlorine in water, it creates hypochlorous acid. This acid destroys waterborne bacteria on contact but deactivates over time. For this reason, you must regularly monitor your hot tub's chemical levels.
What is stabilised chlorine?
Stabilised chlorine has a cyanuric acid stabiliser which protects chlorine from the sun's UV rays. It's ideal for outdoor swimming pools and areas that get a lot of sun, as it ensures your chlorine works effectively, no matter the weather.
How much chlorine should I use?
