Freshwater Spa Care Products

The FreshWater line of Spa Care products has been developed exclusively for Hot Spring spa owners. These products have been approved for use with your spa, and are offered to help you get the most out of your hot tub experience.

Spa Care Starter Kit

A complete FreshWater spa care kit in one convenient box, the kit includes concentrated Chlorinating Granules, MPS Oxidizer, pH Up, pH Down, Defoamer, Stain & Scale, 5-Way Test Strips, and a spa water maintenance & troubleshooting guide. Everything you need to begin enjoying your spa.

5-Way Test Strips

Conveniently monitor the chlorine, bromine, pH, alkalinity and total hardness levels of your spa water with these easy to use test strips.

Concentrated Chlorinating Granules

This efficient sanitizer is popular because it is completely soluble and nearly pH neutral. It is available in 14-ounce, 1.75-pound, and 3-pound bottles.

pH/Alkalinity Up & pH/Alkalinity Down

Up prevents pH bounce and deterioration of spa surface and fittings from low total alkalinity, while Down decreases spa water pH.

Stain & Scale Defense

Prevent calcium build-up on spa surfaces and controls mineral stain and scale formation with Stain & Scale Defences

Spa Shine

Reactive silicone protects, waterproofs and seals the spa shell to prevent fading and oxidation.

Filter Cleaner

Keep your standard or Tri-X® filters in their best condition with the FreshWater filter cleaner to maximize water flow and keep your spa operating efficiently.

Instant Filter Cleaner

Extend the life of your filter with this instant, spray on, “no-soak” formula.


These water and spa care products are used in conjunction with the EverFresh Water Care System.

MPS Chlorine-Free Oxidizer

This fast-acting formula refreshes and brightens spa water. When used with the FreshWaterAg+ purifier, the MPS chlorine-free oxidizer helps activate the silver ions so they can do their job quicker and more effectively. Plus it’s pH neutral, so it won’t alter water chemistry.

Freshwater III High Output Ozone System

Your Hot Spring spa comes standard with the FreshWater III high output ozone system, an essential part of the EverFresh water care system. It uses Corona Discharge cell technology to generate a high concentration of ozone that works to neutralize contaminants on contact and enhance water quality.

MPScents® Oxidizer

This non-chlorine oxidizer with aromatherapy keeps your water clean and creates an inviting and relaxing spa environment. Choose from four soothing scents — Citrus Blossom, Island Escape, Spring Shower, and Zen Garden.

MPS Test Strips

Use these test strips to monitor your spa’s MPS, pH, and alkalinity levels when using the MPS chlorine-free oxidizer as part of the EverFresh water care system.

Continuous Silver Ion (AG+) Purifier

The FreshWaterAg+ continuous silver ion purifier further reduces the need for chlorine by introducing silver ions into the spa water that inhibit bacterial growth. Insert the cartridge into the filter of your Hot Spring® spa and the silver ions are released automatically — there’s no chance of under or over-dosing. Simply replace the cartridge every four months.

Freshwater III High-Output Ozone System

The FreshWater III high output ozone system comes standard on all Hot Spring Highlife® spas, and can be added to any Limelight or Hot Spot spa. An essential part of the EverFresh water care system, it uses Corona Discharge cell technology to generate a high concentration of ozone that works to neutralize contaminants on contact and enhance water quality.


Continuous, silent filteration

The SilentFlo 5000® circulation pump works continuously in your spa, filtering the water for 24 hours a day. It’s totally automatic, so there’s no need to program long cleaning and heating cycles like other spas. Nor do you have the wear and tear, energy drain or noise of a large jet pump running during those cycles. Operating silently and efficiently, your Hot Spring spa is always hot, clean and ready to enjoy.

100% no bypass FILTERATION

With 100% No-Bypass filtration, all the water passes through the filter before it re-enters the spa. With other spas, bypassing occurs when the jets are on — forcing unfiltered water directly back into the spa. With a Hot Spring spa, the gallon-per-minute flow of our pumps is carefully matched with each spa’s square footage to achieve balanced filtration, so there’s no need for bypassing.

Tri-X® FILTER technology

The patented Tri-X filter has twice the cleaning area of other cartridges its size, filtering the water through both the surface and depth. Included as standard on many models, Tri-X filters are dishwasher-safe and can be used on any Hot Spring spa. Available only on the Vista,® Grandee,® Envoy,® and Aria®.

clean screen™ Pre-Filter

Keep your water it’s cleanest every time you fill the spa by using the Clean Screen pre-filter. Attach the Clean Screen to your garden hose to filter out organic contaminants, metals like copper or iron and tannins before they’re introduced to your water.

Vanishing act

Soften hard water without chemical additives by using the Vanishing Act calcium remover. Softer water leaves your skin feel silkier as it helps protect your spa components from the damaging effects of hard water. For areas with extreme hard eater, use the Vanishing XL with 3 times the calcium reduction power of the standard Vanishing Act.
