Restore clarity and freshness to your hot tub with our premium Non-Chlorine Spa Shock. Specially formulated to oxidise and break down organic contaminants that are not removed by your filter, this shock treatment refreshes and reactivates your existing sanitiser, helping to maintain crystal-clear, hygienic water.
By targeting unfilterable waste such as body oils, cosmetics, and other organic debris, it effectively eliminates unpleasant odours, restores a natural sparkle, and enhances the performance of chlorine or bromine-based sanitisers—without increasing chlorine levels.
Perfect for regular maintenance or after heavy use, this non-chlorine shock is ideal for users who prefer gentler, chlorine-free alternatives for ongoing water care.
Key Benefits:
-
Refreshes water and boosts sanitiser effectiveness
-
Dissolves organic contaminants that filters can't catch
-
Reduces unwanted odours and cloudiness
-
Restores clear, fresh-smelling spa water
-
Compatible with chlorine, bromine, and saltwater systems
Usage Tip:
Apply after periods of heavy use, water contamination, or whenever your water appears dull or smells unpleasant. Regular use helps keep your hot tub in peak condition.


Buying and support guide
We supply the Non-Chlorine Spa Shock 1KG with clear specs and UK support. Before you order, check it suits your spa model, size, connector type, power supply and access. This helps you avoid delays and returns.
Replacing a part? Match it to your spa's model and year where you can. For pumps, control packs, heaters, jets, covers, filters, topsides and plumbing, check the part number and connection type. Compare delivery time, warranty and support as well as price.
Running costs matter as much as the price you pay. Energy use, insulation, cover condition, filters and water care all affect long-term value. Replacing worn parts early and keeping the water moving and filtered can save on repairs.
Looking for a whole new tub rather than a part? Compare hot tubs, swim spas and saunas by seating, hydrotherapy, who will use it and the space you have.
