Informations
Strength & Formula
73% available chlorine for fast bacteria and algae kill.
Stabilizer-Free
Won’t raise cyanuric acid (CYA) levels. Great for pools that need a chlorine reset.
Compatibility
Works with most in-ground pool systems. Not for use in indoor or vinyl-lined spas.
What’s the difference between this and stabilized chlorine?
This shock is unstabilized, so it doesn’t raise CYA. It’s ideal for resets or pools already using stabilizer.
Is this safe for saltwater pools?
Yes it is. It works in saltwater systems for occasional superchlorination or spot treatments.
How long should I wait to swim after using it?
Usually 8–12 hours or once chlorine drops below 5 ppm. Always test first.
