Fast Shock Treatment for Fresher, Brighter Spa Water
SpaCare Rapid Shock is a non-chlorine oxygen shock treatment for spas and hot tubs, developed for regular use as part of ongoing spa care.
Fast dissolving and quick acting, it helps freshen the water, improve bather comfort, and restore sparkle for a cleaner, brighter spa finish.
It is a practical treatment for maintaining fresher, more inviting spa water between regular maintenance treatments.

Help Keep Spa Water Fresher, Clearer, and More Comfortable

Reduces Combined Chlorine
Helps reduce and eliminate combined chlorine levels for fresher-feeling spa water.
Improves Bather Comfort
Helps make the spa or hot tub more comfortable to use as part of ongoing water care.
Restores Water Sparkle
Contains a clarifying agent to help give spa water extra sparkle and a brighter appearance.
Fast Dissolving and Quick Acting
Dissolves within 2 to 3 minutes and allows the spa or hot tub to be used 15 minutes after treatment.
Weekly Shock Treatment Support
Used weekly, it helps oxidise organic contaminants and support the overall effect of spa sanitiser.
How It Works
SpaCare Rapid Shock contains a highly concentrated oxygen compound that oxidises organic contaminants in spa and hot tub water. This oxidation process helps reduce and eliminate combined chlorine levels and break down residual contamination that regular sanitising may miss.
It also contains a clarifying agent to help improve water sparkle and overall presentation. Because the formula is fast dissolving and quick acting, treatment begins rapidly after dosing and the spa or hot tub may be used 15 minutes later.

How to Use
- Ensure the pump and filter are turned on.
- Sprinkle the required amount evenly over the surface of the water.
- Allow the product to dissolve fully. Rapid Shock will dissolve within 2 to 3 minutes.
- Wait 15 minutes before using the spa or hot tub.
