Water management

Water care is an important consideration in the hot tub purchase process. The Jacuzzi® water maintenance options make this a simple, easy part of the process.  The water maintenance your spa requires will be determined by how often you use your hot tub and the weather and water quality in your region.  The correct filtration levels and proper water management will insure you always enjoy clean, clear, healthy water in your hot tub.


Proper water care is heavily reliant upon the filtration system and clean water is easy to maintain with a multi-stage filtration process. All Jacuzzi® Hot Tub models have up to five stages of filtration, insuring your water is constantly cleared of debris and healthy for use.     

The ProClarity™ filtration system uses two stages to catch all the tiny particles and debris that other filters miss.

Even when the jets aren’t in use, the ProClear® filter works to clarify your spa water.

Working together, the surface-skimming dam and ProCatch™ bag clean the surface and trap large debris for easy removal.

The pleated cartridge filter removes both large and small particles, providing the cleanest water possible.

Once the multi-stage filtration system has removed all dirt and debris, the system is ready for the water treatment process.


There are four main options for hot tub water care: UV-C, UV-C plus ozone, ozone, and salt water systems. Each water system has its own benefits when used with your spa’s filters and water care products.


Forget the basic water treatment systems of the past. The UV-C technology uses modern science and ultraviolet light to remove bacteria and pathogens in the water. A CLEARRAY light bulb built into the water filtration system emits UV-C power for quick and simple water maintenance. 

UV-C light limits the need for chemicals and keeps the water crystal clear.

Natural UV-C light, emitted by the CLEARRAY bulb, neutralizes 99.9 percent of water-borne pathogens.

After spa use and during scheduled filtration cycles, the UV-C technology is applied in combination with a small amount of chlorine or bromine sanitizer.

The system requires a CLEARRAY® bulb replacement once a year.

CLEARRAY® UV-C technology is odor-free, easy to maintain and durable.


An automatic oxidizer adds another level of protection and insures crystal clear water in your water care system. The UV-C Plus Ozone is a hands-free way to destroy the water borne microorganisms that the UV-C light has neutralized. The CLEARRAY® PRO3TECT Automatic Oxidizer, combined with CLEARRAY® UV-C, further automates the water care process. It is available as a factory-installed upgrade option or in an aftermarket kit.

CLEARRAY® PRO3TECT automatically oxidizes impurities for crystal clear water with minimal time and effort.  It is specifically designed to work with the Jacuzzi®  UV-C technology.

 Jacuzzi® developed a low-output system that releases just the right amount of ozone, creating a powerful oxidizer without any off-gassing. This prolongs the life of your equipment longer than other ozone systems.

The automated design further insures consistently clean, clear water with minimal effort.

The Jacuzzi® UV-C and ozone state-of-the-art technologies - when used together - make it easier than ever to maintain excellent water quality.


Combining UV-C technology with just the right amount of ozone is ideal, however, many newer hot tub models can be equipped with a singular ozonator kit, designed to treat water and help keep the spa cleaner.

The ozonator works to dissolve contaminants hiding in the water.

Ozone brings dissolved solids together, making it easier for your filter cartridge to remove them from the water.

While ozone is a safe option for treating water, unlike CLEARRAY® PRO3TECT™, large amounts of ozone can speed up the breakdown of equipment, such as your hot tub cover.


Salt water hot tub systems use chemical reactions to generate chlorine from salt. For some time, salt cell technology has been used in large bodies of water, such as pools, and it has recently made its way into the portable hot tub product line.

These systems use regular pool salt (sodium chloride). Some users believe this makes for softer water.  

Water needs to be tested weekly. It needs to be shocked with a granular oxidizer at start-up and then once monthly. If you use your salt water hot tub often, you’ll need to shock the system with more frequency.

Sanitizer alternatives, such as bromine, are not for use in salt water systems.

Salt speeds up the process of corrosion on spa equipment and nearby electronics. Be sure to hose off the spa and deck after use to help prevent salt buildup from splashes.

Take special care with salt water chlorine generators. These generators can be sensitive and require close attention to detail, from carefully controlling calcium hardness to cleaning filters that prolong the life of the cell.

A hot tub has a much smaller water volume than a pool. For this reason, it can be easy to over-chlorinate a spa with a salt water chlorine generator.

Salt water hot tub systems are a somewhat new trend, but UV-C technology remains an easy and consistent method of water care, especially when paired with an ozonator.

As a premium spa manufacturer, Jacuzzi® Hot Tubs utilize CLEARRAY® UV-C technology with the option to add a CLEARRAY® PRO3TECT automatic oxidizer, for an effortless water management system. As the owner of a Jacuzzi® Hot Tub, you’ll relish your Jacuzzi® experience knowing you have the cleanest, healthiest water possible.
