Water Enters
the System
Water is continuously drawn from the spa and moved through the Sundance® filtration and circulation system.
True Water™ is an advanced water-care system available as an option on the Sundance® 980™ Series. At The Backyard District, we order every Kingston™ and Claremont® with True Water™ included as our standard configuration.
Unlike a salt water system, True Water™ does not generate chlorine from salt. Instead, it introduces billions of microscopic nanobubbles into the spa water. These incredibly small bubbles remain suspended throughout the water, working alongside Sundance® horizontal filtration and circulation to support exceptionally clean, clear water with less reliance on traditional water-care products.
When True Water™ is selected on a Sundance® 980™ Series spa, it replaces the standard ClearRay® water-care system. Rather than adding another layer on top of ClearRay®, True Water™ becomes the spa’s advanced water-care technology while continuing to build on one of Sundance® Spas’ greatest strengths: filtration first.
The result is a more advanced approach to maintaining beautiful spa water, designed to simplify everyday water care while preserving the performance and water quality Sundance® owners expect.
True Water™ is currently available on the Kingston™ and Claremont® models, bringing the latest evolution in Sundance® water care exclusively to the 980™ Series.
No salt. Advanced nanobubble technology. Sundance® filtration at its foundation. True Water™ as the next evolution.
True Water™ combines advanced nanobubble technology with Sundance® horizontal filtration and continuous circulation to create a more advanced approach to hot tub water care. On a Sundance® 980™ Series spa equipped with True Water™, the system replaces the standard ClearRay® water-care configuration rather than working alongside it.
Water is continuously drawn from the spa and moved through the Sundance® filtration and circulation system.
Sundance® horizontal filters provide a large filtration surface close to the waterline, where oils, debris and other floating contaminants commonly collect.
Billions of microscopic nanobubbles are introduced into the spa water. Their incredibly small size allows them to remain suspended throughout the water far longer than ordinary bubbles.
The water continues circulating throughout the spa, allowing filtration and True Water™ nanobubble technology to work together as part of the ongoing water-care process.
Sundance® horizontal filtration, continuous circulation and True Water™ nanobubble technology working together in one integrated water-care system.
True Water™ is an integrated water-care approach built around nanobubble technology working with Sundance® horizontal filtration and continuous circulation. On a Sundance® 980™ Series spa equipped with True Water™, this configuration replaces the standard ClearRay® water-care system.
True Water™ introduces billions of microscopic nanobubbles that remain suspended in the water far longer than ordinary bubbles.
Because nanobubbles are incredibly small, they behave differently from the visible bubbles produced by spa jets. Their size and stability allow them to remain dispersed throughout the water, supporting a cleaner, clearer and more refined water-care environment.
Nanobubbles remain dispersed throughout the spa water rather than immediately rising to the surface and disappearing.
Nanobubble technology works with Sundance® filtration and circulation to support consistently clean, clear spa water.
True Water™ delivers advanced water-care technology without adding salt or relying on a chlorine-generating salt cell.
Nanobubbles add an advanced layer of water support while working with Sundance® filtration, circulation and properly maintained water chemistry.
Sundance® places its primary filtration close to the waterline, where oils, lotions and floating contaminants commonly collect.
The horizontal filter layout provides a broad filtration surface while helping capture debris before it can continue circulating throughout the spa.
Effective physical filtration removes contaminants from the water and gives True Water™ a cleaner foundation to work from.
Continuous circulation keeps spa water moving through the Sundance® filtration system and allows True Water™ nanobubbles to remain dispersed throughout the water.
Rather than treating water as a one-time event, the spa continually moves water through its filtration and circulation system as part of the ongoing water-care process.
Circulation connects the system, continually moving spa water through filtration while helping distribute True Water™ nanobubbles throughout the spa.



Advanced technology is only valuable if it makes owning your hot tub better.
True Water™ was designed to do more than introduce another piece of technology to your spa. By combining nanobubbles with Sundance® filtration, the system supports cleaner, clearer water while helping simplify everyday water care.
Cleaner, Clearer Water
True Water™ works throughout the spa water alongside Sundance® filtration to support exceptional water clarity.
Less Reliance on Chemicals
By adding additional water-care technology to the Sundance® system, True Water™ can help reduce the demand placed on traditional water-care products while still maintaining the sanitizer residual required for safe spa water.
No Salt System Required
True Water™ delivers an advanced water-care experience without adding salt or requiring a chlorine-generating salt cell.
Designed to Work Together
Rather than adding a standalone aftermarket system, True Water™ works as part of the Sundance® approach to circulation, filtration and water care.
Less Time Thinking About Water. More Time Enjoying It.
Ultimately, that is what better water care should accomplish. True Water™ is designed to help make maintaining beautiful spa water easier, so owning your Sundance® Spa feels a little more like enjoying it and a little less like maintaining it.
Sundance® 980™ Series spas come standard with the ClearRay® water-care system, while True Water™ is available as an optional upgrade. Both configurations retain Sundance® horizontal filtration and circulation, but when True Water™ is selected, it replaces ClearRay® with advanced nanobubble technology.
Sundance® horizontal filtration provides a broad filtration surface near the waterline, where oils and floating contaminants commonly collect.
True Water™ retains the same Sundance® horizontal filtration foundation as part of its water-care configuration.
Water continuously circulates through the Sundance® filtration and water-care system.
Continuous circulation moves water through filtration while helping distribute True Water™ nanobubbles throughout the spa.
ClearRay® is the standard water-care configuration on Sundance® 980™ Series spas when True Water™ is not selected.

Both systems are designed to support a better hot tub ownership experience, but they work in fundamentally different ways. True Water™ uses advanced nanobubble technology alongside Sundance® horizontal filtration and circulation. Salt water systems use dissolved salt and a generating cell to produce chlorine.
True Water™ does not require salt to be added to the spa water.
Salt is dissolved into the water and maintained within the range required by the system.
True Water™ does not use an electrolytic cell to generate chlorine.
The system converts dissolved salt into chlorine as part of its sanitation process.
Billions of microscopic nanobubbles remain dispersed throughout the spa water as part of the True Water™ system.
Salt generation and nanobubble technology are separate water-care approaches.
There is no chlorine-generating salt cell to inspect, clean or replace.
The generating cell requires routine inspection and may eventually require cleaning or replacement.
True Water™ is designed to support a clean, comfortable and refined spa-water experience without adding salt.
Dissolved salt can contribute to the softer water feel often associated with salt water systems.
True Water™ supports the overall water-care process but does not eliminate the need for properly maintained sanitizer levels.
The salt cell produces chlorine, but owners must still monitor sanitizer levels and overall water balance.
Owners still test and balance pH, alkalinity, sanitizer and other essential water-care levels.
Owners must balance standard water chemistry while also monitoring salt level and chlorine output.

Sundance® True Water™ is an advanced hot tub water-care system available on the Sundance® 980™ Series. It combines nanobubble technology with Sundance® horizontal filtration to support clean, clear spa water.
True Water™ is designed to build on the existing Sundance® water-care platform rather than replace it.
No. Sundance® True Water™ is not a salt water system.
It does not require salt to be added to the spa, and it does not use an electrolytic salt cell to generate chlorine. Instead, True Water™ uses nanobubble technology alongside Sundance® filtration support.
True Water™ is currently available exclusively on the two Sundance® 980™ Series models:
Kingston™
Claremont®
It is not currently available throughout the full Sundance® lineup.
True Water™ supports the overall water-care process, but spa owners must still follow the approved Sundance® water-care routine and maintain properly balanced water.
True Water™ should not be treated as a replacement for routine water testing or the sanitizer residual recommended for the spa.
Traditional Sundance® water care already uses horizontal filtration and circulation technology to support water quality.
True Water™ builds on that foundation by adding integrated nanobubble technology. It does not remove or replace the existing Sundance® filtration components.
The main difference is how the systems work.
A salt water hot tub uses dissolved salt and a generating cell to produce chlorine. True Water™ does not add salt or generate chlorine from salt. It uses nanobubbles alongside Sundance® filtration.
Both systems still require appropriate testing, water balancing and ongoing care.
Nanobubbles are extremely small bubbles that behave differently from the visible bubbles produced by hot tub jets.
Because of their microscopic size, they can remain dispersed in water longer than ordinary bubbles. In the True Water™ system, nanobubble technology works as part of the broader Sundance® approach to filtration and water care.
Yes. True Water™ does not eliminate routine water testing.
Spa owners should continue checking the water and maintaining the appropriate pH, alkalinity, hardness and sanitizer levels recommended for their Sundance® Spa.
No hot tub water-care system can guarantee that an individual will not experience irritation.
Properly balanced water is essential, and people with sensitive skin or specific medical concerns should follow professional medical advice. True Water™ owners must still maintain the water according to Sundance® recommendations.
True Water™ is available on the Sundance® Kingston™ and Claremont® models.
The Backyard District can help you compare the two 980™ Series spas, explain how the system works and determine which model best fits your seating, hydrotherapy and space requirements.
True Water™ brings nanobubble technology to the Kingston™ and Claremont™ spas, building on Sundance® filtration and ClearRay® UV-C technology without converting your spa into a salt water system.
