Spa Shock-Oxidizer, 7lb
FEATURES
- Non-Chlorine Shock Treatment: SpaGuard Spa Shock-Oxidizer is a non-chlorine hot tub shock-oxidizer for use in bromine and chlorine spa sanitation systems. It does not raise chlorine residual and an easy to use, quick-dissolving shock treatment.
- Clarifies Water: SpaGuard's Spa Shock-Oxidizer enables spa owners to use a non-chlorine based shock-oxidizer treatment that stabilizes your spas pH level to prevent any bounce as well as producing crystal clarity to your water by removing any microscopic organic contaminants missed by the filtering system.
- Keeps a Clear & Healthy Spa: SpaGuard Spa Shock-Oxidizer is designed to provide the oxidation power needed to keep a clear and healthy spa without raising the chlorine or bromine levels. This makes it ideal for when you need to shock the hot tub shortly before use. Do not use Hot Tub within 15 minutes after addition of Spa Shock.
- Compatibility: Spa Shock-Oxidizer's formula does not replace sanitizers or algaecides, and is compatible with chlorinating and brominating sanitation systems.
- Tested and Proven Effective: SpaGuard products are known for delivering reliable results and making spa care less complex. SpaGuard carries an extensive line of spa solutions that match your unique needs.

Questions We Get a Lot
Still stuck? Our team answers by email within one business day.
Are these genuine BioGuard and SpaGuard products?
Yes. Every product ships sealed from the manufacturer with current lot codes and expiry dates. We do not sell repackaged or relabelled chemicals.
How fast will my order arrive?
Orders placed before 2pm on a business day ship the same day. Most deliveries land in three to five business days. Shipping is free over $150.
Which chlorine should I use, tablets or granular?
Tablets dissolve slowly and hold a steady level week to week, so they suit routine care. Granular works fast and is what you reach for after heavy rain, a party, or an algae bloom. Most pools run tablets as the base and keep granular on hand.
Can I ship pool chemicals by air or overseas?
Most sanitizers and shock are classed as oxidisers, so they travel by ground only and cannot go by air. Restrictions show at checkout once you enter your address.
What if I ordered the wrong product?
Unopened products can be returned within 30 days. Chemicals cannot be returned once the seal is broken, for safety reasons. Message us before you open anything you are unsure about and we will help you work out what you actually need.
