Description After using your hot tub, oils, lotions, and organic waste build up in the water — leaving it dull, tired, and sometimes with an unpleasant smell. TubLux Non-Chlorine Shock works by breaking down these contaminants, helping to clean and refresh your water without changing your chlorine or bromine levels. It’s ideal for weekly use or after heavy use to keep your hot tub water feeling fresh, clean, and ready to enjoy. When to use:After using your hot tub, after multiple bathers, or weekly as part of your regular water care routine. How to use:Add directly to the water with the cover off and jets running. Allow the water to circulate for at least 1 hour. Works best with:Regular sanitiser levels and a clarifier to maintain crystal clear water. Keeps your water fresh without the harsh effects of chlorine-based shock treatments. If your water has become difficult to manage or issues keep returning, it may be a sign of a deeper problem – our hot tub diagnostic service can identify the cause and get everything back on track.
