What is lithium spa sanitiser?
Lithium Spa Sanitiser is a specialised spa water treatment that eliminates bacteria and contaminants, ensuring clean and safe water in spa pools and swim spas.
Previously available in granular form in Australia, lithium-based sanitisers became scarce around 2018 due to the increasing demand for lithium in battery production for electric vehicles and electronics.
Now, lithium is available again as a spa sanitiser in an innovative liquid form.
This new Liquid Lithium Sanitiser offers several key benefits:
- Ultra-Pure Formula – Contains only two ingredients: lithium and water, ensuring a clean and effective sanitisation process.
- Highly Efficient – Works exceptionally well in the warm water of spa pools and swim spas.
- Easy to Use – No complex dosing or mixing is required, making spa maintenance simple and hassle-free.
" Lithium spa sanitiser is a great option for those looking for a gentler, more stable way to keep their spa water clean."

How does lithium spa sanitiser work?
Lithium Spa Sanitiser keeps your spa water clean and safe by eliminating bacteria, viruses, and other harmful microorganisms. It works through a powerful disinfection and oxidation process:
- Formation of Hypochlorite Ions: The active ingredient, lithium hypochlorite, dissolves in water, releasing hypochlorite ions (OCl⁻) and lithium ions (Li⁺).
- Disinfection Reaction: The hypochlorite ions attack and break down bacteria, algae, and other microorganisms, preventing them from multiplying.
- Oxidation Process: These ions disrupt the cell membranes, proteins, and genetic material of harmful organisms, effectively destroying them.
- Residual Chlorine: A small amount of residual hypochlorite remains in the water, ensuring continuous protection against future contamination.
This process ensures that your spa water remains crystal clear, hygienic, and safe for relaxation and enjoyment.
How to Use Liquid Lithium to Sanitise Your Spa
Maintaining clean and safe spa water with Liquid Lithium is a straightforward process. Follow these key steps for effective sanitation:
- Check the Product Instructions – Always use the recommended dosage based on your spa’s water capacity. Refer to the product label for precise measurements.
- Maintain Balanced Water Chemistry – For optimal performance, keep your spa’s pH between 7.2–7.8 and total alkalinity between 60–200 ppm. Regular testing is recommended.
- Initial Shock Treatment – When filling your spa with fresh water, add 160 ml per 1000 litres to establish a sanitising level. This helps eliminate contaminants introduced during refilling.
- Ongoing Maintenance – Test the water daily and maintain a chlorine level of 3–4 ppm, adjusting the dose as needed to ensure continued sanitation.
- Weekly Shock Treatment – To help break down organic matter and prevent bacteria or algae buildup, add 80 ml per 1000 litres weekly.
By following these steps, you can help keep your spa water clear, hygienic, and comfortable for regular use. Regular monitoring and adjustments will ensure a well-balanced and properly sanitised spa environment.
