Maintaining the water quality of your inflatable hot tub is crucial for ensuring a safe and enjoyable experience. One key aspect of this maintenance is knowing when and how to shock your hot tub. Shocking the water helps to keep it clean and hygienic by eliminating bacteria and other contaminants. This article will guide you through understanding the right time and frequency for shocking your inflatable hot tub.

What Does “Shocking” a Hot Tub Mean?

Shocking a hot tub refers to the process of adding a chemical treatment, typically chlorine or non-chlorine shock, to the water. This treatment breaks down organic contaminants like sweat, oils, and urine, as well as kills bacteria and algae. It also helps to clear cloudy water and remove unpleasant odors.

When to Shock Your Inflatable Hot Tub

1. Regular Maintenance:

  • Weekly Basis: As a general rule, you should shock your inflatable hot tub once a week as part of regular maintenance.
  • Follow Manufacturer’s Guidelines: Always refer to your hot tub’s manual for specific recommendations.

2. After Heavy Use:

  • If the hot tub has been used by several people or for an extended period, it’s advisable to shock the water immediately afterward.

3. Changes in Water Clarity or Quality:

  • Shock the hot tub if you notice the water becoming cloudy, discolored, or if there’s an unusual smell.
  • These changes can indicate a high level of contaminants.

4. After Refilling:

Whenever you drain and refill your hot tub, shock the water to establish a sanitizer baseline.

5. Following a Period of Inactivity:

If the hot tub hasn’t been used for an extended period, shocking the water can help refresh it.

How to Shock Your Inflatable Hot Tub

  1. Choose the Right Shock Product:
    • Use either chlorine-based or non-chlorine shock treatments, depending on your preference and the hot tub’s requirements.
  2. Read Instructions Carefully:
    • Follow the manufacturer’s instructions for the correct amount and method of adding the shock to your hot tub.
  3. Turn On the Jets:
    • Activating the jets helps to distribute the shock treatment evenly throughout the water.
  4. Wait Before Using:
    • Allow the shock treatment to work for the recommended amount of time before using the hot tub. This is usually a few hours.
  5. Test Water Balance:
    • After shocking, test the water to ensure it has the correct pH, alkalinity, and sanitizer levels.

Safety Tips

  • Wear Protective Gear: Use gloves and goggles when handling hot tub chemicals.
  • Store Chemicals Safely: Keep hot tub chemicals in a cool, dry place away from children and pets.


Regularly shocking your inflatable hot tub is an essential part of maintenance that keeps the water safe and pleasant for use. By following a consistent schedule and responding to specific needs such as heavy use or changes in water quality, you can maintain a clean and healthy hot tub environment. Remember, a well-maintained hot tub is the key to countless hours of relaxation and fun.
