SpaGuard's Spa Shock enables spa owners to use a non-chlorine based shock 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. Spa Shock's formula does not replace sanitizers or algaecides, and is compatible with chlorinating and brominating sanitation systems.
