A Complete Guide to Superchlorination and Shock Treatment for Your Pool
Swimming pool maintenance requires regular attention, especially during hot weather or after heavy use. One critical maintenance procedure is superchlorination, commonly known as “shock treatment.” This process helps maintain proper sanitisation and water clarity in your pool.
What is Shock Treatment?
Shock treatment is an additional dose of chlorine added to your pool to quickly raise the sanitiser level. This extra boost helps eliminate contaminants, bacteria, and algae that might be resistant to normal chlorine levels.
There are two main levels of shock treatment:
- Standard Shock Treatment: Adding double the normal dose of chlorine
- Superchlorination: Adding approximately four times the normal dose of chlorine
When to Shock Your Pool
Regular shock treatments are essential for both chlorine and saltwater pools. Consider shocking your pool:
- More often during hot summer months
- After heavy pool usage (parties, multiple swimmers)
- Following rainstorms or other weather events
- When water appears cloudy or has visible algae
Best Practices for Shock Treatment
For optimal results:
- Add chemicals in the evening to prevent rapid chlorine degradation from sunlight
- Follow manufacturer’s dosing instructions carefully
- Allow chlorine levels to return to normal before swimming
- Run your filtration system during and after treatment
Choosing the Right Shock Treatment
The appropriate shock treatment for your pool depends on several factors:
- Pool type (saltwater or traditional chlorine)
- Current stabiliser levels
- Pool surface material
