Essential Chemicals for Swim Spa Water Care
Maintaining pristine swim spa water starts with having the right chemicals on hand. Essential chemicals include pH Up, pH Down, chlorine granules, oxidizer, and filter cleaner. These chemicals play vital roles in maintaining the water quality and ensuring that your swim spa remains a healthy and enjoyable place to relax.
Preventing bacteria and algae growth is key in swim spa maintenance. Chlorine granules are the primary sanitizing agent, ensuring the swim spa water is safe for use. Maintaining a pH level between 7.4 and 7.6 ensures effective water balance. Use pH Up and pH Down to easily adjust pH and total alkalinity as needed.
Additionally, using an oxidizer shock helps free up bound chlorine, improving overall sanitation. Using a filter cleaner regularly helps maintain the efficiency of your swim spa filters by removing debris and build-up, ensuring optimal water flow and filtration. Keeping these chemicals stocked and using them as part of your swim spa maintenance routine will keep your swim spa water clean and safe for all to enjoy.
Testing Your Swim Spa's Water Regularly
Regular water testing is a cornerstone of effective swim spa maintenance. Routine swim spa test water helps identify imbalances or contaminants, ensuring that the water remains safe and clean for use. Regular testing prevents potential skin and eye irritation caused by unbalanced chemical levels.
Test kits or strips help determine appropriate chlorine levels and pH balance for maintaining water quality. An ideal pH range between 7.2 and 7.8 ensures effective sanitation and comfort. Adjust chlorine levels based on usage frequency and the number of users.
To make water testing even more convenient, consider using Spa Sense™ by Sundance Spas. This innovative system connects to the Smart Tub app and provides personalized water care recommendations based on your specific spa model. Spa Sense™ measures chlorine, pH, and alkalinity multiple times a day, eliminating the need for hard-to-read test strips and ensuring your swim spa water remains in optimal condition.
Adjusting Alkalinity and pH Levels
Proper pH and total alkalinity levels are vital for swim spa water quality and longevity. Unbalanced water can lead to corrosive conditions that damage the spa’s components. Consistent testing and adjustments keep the water balanced, prolonging the lifespan of your swim spa.
Start with alkalinity adjustments before moving on to pH when balancing chemical levels. This is because alkalinity changes significantly impact pH, while pH adjustments have minimal influence on alkalinity. To raise alkalinity, use pH Up, and to lower it, use pH Down. Add chemicals gradually and wait about 30 minutes before retesting the water.
Balancing pH and total alkalinity keeps the water safe and comfortable while protecting the spa’s components. By keeping these levels within the normal range, you’ll prevent issues such as skin irritation and ensure effective sanitation.
Sanitizing Your Swim Spa Water
Sanitizing swim spa water ensures a clean and healthy environment. Free available chlorine (FAC) should be maintained between 2–4 ppm to ensure effective sanitation. Bromine is another popular sanitizer, with recommended levels between 3-6 ppm for optimal effectiveness.
Shocking the water regularly eliminates contaminants like sweat, oils, and organic waste. It also removes odors from chloramines, keeping the water fresh and pleasant. Both chlorine and non-chlorine shock treatments can be used depending on the water conditions and the specific needs of your swim spa.
The amount of sanitizer required can vary based on the number of people using the spa and the duration of use. Low free chlorine levels might indicate the need for more frequent shocking or adjusting the sanitizer dosage. Maintaining proper sanitizer levels and regular shocking keep the water clean and safe for everyone.
Shocking Your Swim Spa
Regular shocking is vital for maintaining water quality and hygiene. The primary purpose of shocking is to eliminate chloramines, bromamines, and other impurities that can build up over time. These compounds can cause unpleasant odors and reduce the effectiveness of your sanitizer.
It’s recommended to shock your swim spa on a monthly basis to keep the water clean and fresh. After each use, consider adding about 9 teaspoons of chlorinating granules per 500 gallons of water to manage odors and prevent algae growth.
Regular shocking ensures continued sanitary conditions and a pleasant experience for all users.

Cleaning Your Swim Spa Filters
Cleaning swim spa filters regularly maintains water quality and efficiency. Use filter cleaner to remove debris and build-up from filter media, keeping your filters in top condition. For a deep clean, submerge the filter in filter cleaner overnight, then rinse thoroughly before reinserting.
It’s important to regularly rinse your filters to maintain their efficiency and ensure optimal water flow. During the cleaning process, check the filters for any tears or damage and replace them if necessary.
After soaking the swim spa filter in filter cleaner, rinse it with clean water and ensure it is completely dry before reinserting it into the swim spa.
Regular filter cleaning keeps your swim spa water clean and extends filter life, ensuring a better experience.
Draining and Refilling Swim Spa Water
Draining and refilling swim spa water is essential for maintenance. Change the swim spa water every 3-6 months, depending on usage and other factors. Typically, swim spa water should be changed 3-4 times a year to maintain optimal water quality.
During a full water change, drain all the water from the swim spa, perform a deep clean, and refill it with fresh water. Using a submersible pump can shorten the draining time to 30-45 minutes, making the process more efficient.
Regular water changes keep your swim spa water clean, ensuring a pleasant experience.
Maintaining Your Swim Spa's Cover
