How often do you change the water in a swim spa?

The frequency of changing the water in a swim spa depends on several factors, including the level of use, water quality maintenance, efficiency of the in-built filtration system, and whether it's used for exercise or therapeutic purposes.

Generally, it's recommended to change the water in a swim spa every 4 to 6 months. Here are some more detailed considerations:

Usage Level:

If the swim spa is used frequently, or by multiple people, it might require more frequent water changes due to the accumulation of body oils, lotions, and other contaminants.

Water Quality Maintenance:

Regular testing and maintenance of water chemistry (such as pH, alkalinity, and sanitiser levels) are crucial.

If you are diligent and maintain high water quality through filtration, sanitisation, and use of clarifiers or conditioners, you might be able to extend the time between water changes.

Surrounding Environment:

If the swim spa is in an environment where it collects a lot of debris, like leaves or dirt, this might necessitate more frequent cleaning and water changes.

Filtration System:

Maintaining a clean and efficient filtration system helps prolong the time between complete water changes.

Regularly clean and replace filters as recommended by the manufacturer.

Manufacturer Recommendations:

Always refer to your manufacturer’s guidelines as they might have specific recommendations for water change frequency based on the model and features of your swim spa.
