What is Chlorine Shock?
Chlorine shock is a harsh chemical that kills bacteria, viruses and algae in your hot tub in a short period. It works quickly and efficiently, particularly when there is heavy work on the water or when the water appears to be dirty.
The major facts concerning chlorine shock:
- Strong disinfectant
- Kills bacteria, algae and germs quickly
- Frequently required to wash thoroughly following intensive work
- Takes more time before resuming the use of the spa (typically 24 hours)
- May leave a smelly chlorine in water
What is Non-Chlorine Shock?
Using an environment friendly shock is a safe way to oxidize waste in your hot tub water. This non-chlorine option, often potassium monopersulfate, is oxygen-based, milder than chlorine, and effective for routine maintenance.
Considerable facts regarding non-chlorine shock:
- Eliminates oils, sweat and organic garbage
- Safe for sensitive skin
- No strong chlorine smell
- Minimal waiting period (approximately 15–30 minutes)
- Not a bacterium killer, must be coupled with a sanitizer
