Maintaining your swim spa is crucial to ensuring the equipment stays clean, safe, and functioning properly throughout the year. If you don’t regularly maintain your swim spa, you’re more likely to experience water quality problems, equipment damage, and the need to spend more money to fix them. By doing regular maintenance on your swim spa, you can continue to take advantage of your swim spa for relaxation, exercise, or hydrotherapy without interruption.
A very important part of maintaining your swim spa properly is ensuring that your water chemistry is balanced properly. You should test your swim spa’s water at least 2-3 times each week by using test strips or a liquid test kit to do so. The important things to look for are the pH, total alkalinity, and sanitizer levels.
You need to make sure that the pH is between 7.2 and 7.8 so that it does not corrode the equipment and also does not irritate your skin or eyes. The total alkalinity is to be between 80 and 120 ppm in order to stabilize your pH levels. Finally, you need to keep your sanitizers (chlorine or bromine) at the appropriate levels so that they keep the water free from harmful bacteria. Reacting to any variations in these chemical levels before they cause issues will help you to avoid problems such as cloudy water, scaling, and biofilm created by bacteria in the water.
The filtration system is an important element for your swim spa to ensure that all the debris, oils, and other contaminants in your water are removed. Depending on how often you use your swim spa and the types of conditions that your swim spa is exposed to will determine how often you should clean your filters; generally, every 2-4 weeks is a typical cleaning period. Additionally, every few months, you should soak your filters in a filter cleaning solution to remove built-up oils and minerals from your filters.
Maintaining proper circulation is an important part of ensuring the water in the swim spa has been appropriately treated and that the chemicals used have been fully dispersed throughout the water. Running your circulation pump for a minimum of 4–6 hours per day will help to provide consistent water quality and to decrease the likelihood of stagnant water occurring in the swim spa.

A clean swim spa is not only desirable but also makes it healthier for use. Performing routine cleaning of the swim spa shell and the waterline on a weekly basis will help to reduce the buildup of grime and biofilm and help to keep the swim spa cleaner for longer periods of time. The jets will collect debris, which affects their performance, so be sure to clean the jets in the swim spa regularly.
In addition, it is recommended to drain and refill your swim spa every 3–4 months, or more frequently if you use it frequently, in order to refresh the quality of the water and reduce mineral buildup. It is also important to always cover an outdoor swim spa with a quality cover to prevent UV damage to the shell and to lessen the likelihood of debris accumulating in the swim spa.
While the majority of swim spa maintenance can be done by the homeowner on a regular basis, having a professional inspection performed on your swim spa at least once or twice a year will help to identify potential problems early.
A professional will inspect all electrical components, pumps, heaters, and the overall swim spa to ensure that everything is operating properly and safely. Taking a proactive approach to your swim spa maintenance may lower the overall cost of repairs and maximize the life of your swim spa.
By following these essential maintenance tips for your swim spa, you will be able to enjoy clean, safe, and functioning water all year long. Regular maintenance protects your investment and enhances your experience of relaxation and wellness.
