For Hot Tubs & Swimming Pools
OXY Granules 1kg are a chlorine-free active oxygen shock treatment designed for hot tubs, swimming pools, spas, whirlpools, and wellness systems. Active oxygen is a powerful oxidising agent that destroys bacteria and organic contaminants without chlorine or bromine, making it ideal for sensitive users.
Best used as a weekly shock treatment or for initial water treatment, rather than as a sole daily sanitiser.

What Is Active Oxygen Shock?
Active oxygen works by oxidising bacteria and contaminants in the water. While it is highly effective, it is also less stable than chlorine or bromine, which means:
✔ Excellent as a shock treatment
✔ Ideal for weekly maintenance
❌ Not recommended as the only daily sanitiser unless chlorine/bromine cannot be used
For best results, use OXY Granules as a shock, alongside regular maintenance chemicals.
⸻
When to Use OXY Granules
•After filling fresh water
•Once per week as a shock treatment
•When chlorine or bromine levels drop to zero
•After heavy bather use
•For users allergic to chlorine or bromine
For commercial or heavily-used spas, shock treatment may be required daily.
