How Simple Silver Works
Simple Silver uses the natural antimicrobial power of silver ions to continuously sanitize your spa water, the same technology used in medical and food-safety applications worldwide. Drop in one tablet, keep your filters clean, and enjoy pristine water for up to 12 months. That's it.
No measuring. No mixing. No chemical smell.
Who Is Simple Silver For?
Simple Silver is compatible with the majority of spa pools including acrylic, fibreglass, and timber barrel spas. It requires adequate water circulation to work effectively, so it is not recommended for inflatable spas with insufficient circulation systems.
- Spa pool owners with sensitive skin, eczema, or allergies to chlorine/bromine
- Families with young children or pets who use the spa regularly
- Anyone who wants less maintenance and more relaxation
- Eco-conscious households reducing chemical use at home

Setup and Maintenance Guide
Getting Started
- Drop the Simple Silver tablet into your spa - no testing or measuring required

Ongoing Maintenance
- Clean your spa filters with 1L Filter Cleaner Soak for Pool and Spa weekly to fortnightly depending on usage - this is the most important maintenance step
- No additional sanitizers, shock treatments, or water balancers are needed
Annual Reset (After 12 Months)

- Use a spa pipe cleaner to flush and purge the pipes before refilling
