Restore Sparkle the AquaSpa Way
AquaSpa Spa Shock is the freshness-support step in the AquaSpa chlorine-free and bromine-free spa system, helping keep spa water bright, fresh, and inviting as part of regular spa care.
Used as part of the AquaSpa routine, it helps oxidise the wastes and contaminants that build up in warm spa water and can affect clarity, freshness, and overall water finish. The result is water that looks cleaner, feels more pleasant, and stays more in line with the calm, comfortable AquaSpa experience.
Fast acting and easy to use, AquaSpa Spa Shock supports both the AquaSpa sanitising step and the spa filtration system, making it an important part of maintaining clearer water, better sparkle, and more confident day-to-day spa care.
Why AquaSpa Feels Different
Helps restore sparkle and freshness
Supports brighter, fresher-looking water by helping remove contaminants missed during normal sanitising.
Supports clearer water
Helps maintain water clarity in warm spa conditions where organic residue can build up quickly.
Improves overall spa comfort
Helps reduce odours and restore a cleaner, more enjoyable water finish for regular use.
Works with the AquaSpa system
Supports AquaSpa Spa Sanitiser and the spa filter so sanitation and filtration work more efficiently together.
Fast acting when needed
Acts quickly and can be used weekly or after heavier spa use to help bring back water freshness and clarity.
Chlorine-free support step
Provides oxidation support without adding chlorine or bromine to the AquaSpa routine.

How It Works
AquaSpa Spa Shock is a chlorine-free oxidiser made with potassium monopersulphate. In warm spa and hot tub water, wastes and other organic contaminants can build up through normal use and reduce freshness, affect water clarity, and place extra load on both sanitising and filtration.
AquaSpa Spa Shock works by oxidising this waste material so it can be dealt with more effectively by AquaSpa Spa Sanitiser and the spa filtration system. This helps destroy odours and wastes missed during normal sanitising, improves water sparkle, and supports a fresher, more comfortable spa environment. It is also fast acting, so a spa or hot tub may be used 15 minutes after dosing.
How to Use
- Calculate the correct spa volume before dosing.
- Ensure the filtration pump is running.
- Add AquaSpa Spa Shock directly to the spa water at the required dose.
- Leave the cover off for at least 30 minutes after dosing.
Dosage & Coverage
- Standard Dose: 20g per 1,000 litres of spa water
- Frequency: Once every week under normal conditions
Important Usage Information
- Approved for use in spas and hot tubs as part of the AquaSpa chlorine-free and bromine-free care system.
- Always dose accurately according to spa volume, add chemicals to water and never water to chemicals, and do not overdose.
- If adding other AquaSpa products, allow 30-minute intervals between each chemical addition.
- May also be used after each use if extra oxidation support is needed for optimum water clarity.
Maintain pH at 7.4–7.6, total alkalinity at 125–150ppm, and calcium hardness at 200–275ppm for concrete and tiled spas and hot tubs, or 175–225ppm for other surfaces. AquaSpa Spa Shock supports oxidation and clarity within the AquaSpa system and does not replace the ongoing sanitising step.

Frequently Asked Questions
Do I still need AquaSpa Spa Shock if I already use Spa Sanitiser?
Yes. AquaSpa Spa Sanitiser is the ongoing sanitising step, while AquaSpa Spa Shock is the oxidation step. It helps deal with wastes and contaminants that can affect water clarity, freshness, and sparkle between doses.
What does AquaSpa Spa Shock help with?
It helps oxidise wastes and contaminants that can reduce sparkle, affect freshness, and make water look dull or tired. It also helps support the AquaSpa sanitising step and the spa filter.
Can I use the spa soon after adding AquaSpa Spa Shock?
Yes. A spa or hot tub may be used 15 minutes after dosing.
Can I use AquaSpa Spa Shock on its own?
For best results, use it as part of the full AquaSpa program. AquaSpa Spa Shock is designed to work alongside AquaSpa Spa Sanitiser, AquaSpa Spa Kleer, balanced water, and good filtration.
Can I add AquaSpa Spa Shock with other AquaSpa products on the same day?
Yes. Keep the filtration pump running, leave the cover off, and allow 30-minute intervals between each chemical addition.
Why might I need an extra dose after use?
Heavier-than-normal bather loads can leave more waste in the water, so an extra dose after use can help restore clarity, freshness, and sparkle.
