Spa Shok Ultra is a chlorine-free oxidizing shock from Summer Smiles (Sani Marc), made specifically for spas. It actively eliminates the organic waste regular use leaves behind — perspiration, body oils, cosmetics — restoring water clarity fast and reactivating the bromine or chlorine already in your water so your sanitizer works longer.
It’s concentrated: 50 g treats up to 1,000 litres of spa water. Dose for dose, that’s roughly three times the strength of Arctic Pure Refresh — if you’re switching between the two, adjust the scoop, not the routine.
How to use it: once a week (or after a heavy bather load), with the pumps running, add the dose for your spa’s volume and let the water circulate with the cover off while it oxidizes.
Quick tips:
- Chlorine-free means quick turnaround — you’re back in the water far sooner than after a chlorine shock
- Works with chlorine, bromine and salt systems alike
