FreshWater Salt Test Strips | Salt Level Testing

• 1 bottle of FreshWater Salt Test Strips — 25 strips in a sealed, moisture-resistant flip-top container
• Color-match comparison chart — printed directly on the bottle label, calibrated for salt level readings
• Desiccant pack — sealed inside the bottle to keep remaining strips dry between uses
• Manufacturer use and storage instructions — printed on the label

• Dedicated salt measurement — purpose-built for the salt range needed by FreshWater and ACE systems (500–2,500 ppm)
• 10-second read time — quick dip, quick result
• Color-match chart on the bottle — no app, no booklet to lose
• Works with both salt systems — FreshWater Salt System and Hot Spring ACE
• 25 strips per bottle — months of regular testing
• Sealed bottle with desiccant — strips stay accurate through the full pack as long as the cap is closed promptly
• Made by Watkins Wellness — calibrated to the same salt targets the manufacturer specifies for your spa
• Universal salt system fit — works for any spa running a Watkins Wellness saltwater system, regardless of model year

FreshWater Salt Test Strips use a single reagent pad that reacts to the chloride ion concentration in your spa water. The more dissolved salt, the more intense the color change. After 10 seconds, you match the pad to the color chart on the bottle to read your salt level in parts per million (ppm).

The strip is calibrated for the specific salt range a Watkins Wellness salt system needs to operate:

• Below 1,500 ppm — salt is too low; cartridge can't generate enough chlorine
• 1,500–2,000 ppm — proper operating range
• 1,750 ppm — ideal target
• Above 2,000 ppm — salt is too high; risk of accelerated equipment wear and possible corrosion

Unlike chlorine or pH, salt levels change slowly and predictably — they don't swing day to day. Most well-maintained spas hold their salt level for weeks at a time, drifting downward only as water leaves the spa via splash-out and evaporation top-offs. The test confirms when it's time to add salt — and just as importantly, when not to add salt.

Pro Tip: If you fill your spa with water that runs through a household water softener, your fill water already contains some salt. The salt strip can detect that residual — useful for adjusting the initial dose at fresh fill so you don't end up over-salted. Always test fill water before adding any salt.

Testing Your Salt Level

1. Remove one strip from the bottle and reseal the cap immediately. Moisture in the bottle is the most common cause of expired strips.
2. Dip the strip into the spa water for 10 seconds, swirling gently to make sure the reagent pad has full contact with water.
3. Pull the strip straight out of the water. Do not shake or wipe.
4. Hold the strip horizontally (pad facing up) and wait for the pad to fully develop color — typically immediate.
5. Compare the pad to the color chart on the bottle. Read in good light, away from direct sunlight or harsh shadow.
6. Record the reading or photograph it for reference.

How Often to Test

• Weekly as part of routine water testing for most owners
• Before adding salt at any time — confirm you actually need to add salt before doing so
• After topping off the spa with fresh water — dilution lowers salt concentration
• After every drain-and-refill — verify the new salt dose put you in range before treating it as a finished refill
• Anytime the spa controller warns of low chlorine generation or low salt

Interpreting Your Reading

• Below 1,500 ppm — add FreshWater Spa Salt one cup at a time, dissolve fully, and retest. Do not dump a full bag at once.
• 1,500–2,000 ppm — proper range. No action needed.
• Around 1,750 ppm — ideal target.
• Above 2,000 ppm — too high. Remove some spa water and replace with fresh water to dilute. Retest before adjusting further.

Storage

• Keep the bottle tightly closed between uses.
• Store at room temperature, away from direct sunlight, humidity, and chemical fumes.
• Do not store in the spa cabinet or any other location that gets damp.
• Note the expiration date printed on the bottle. Strips typically remain accurate for 1–2 years from manufacture if stored correctly.
• Never touch the reagent pad with wet fingers, and never return an unused strip to the bottle.

Pro Tip: Over-salting is harder to fix than under-salting. If you're adding salt for the first time after a fresh fill, start with about70%of the dosage chart amount, dissolve fully, then test and add more in small increments until you hit the target. It's much easier to add another cup than to drain water to dilute.

FreshWater Salt Test Strips are calibrated specifically for spa-grade salt concentrations between 500 and 2,500 ppm — the operating range for Watkins Wellness saltwater sanitizing systems.

Compatible Systems

• FreshWater® Salt System — the current generation, available on Hot Spring Highlife / Limelight and Caldera Utopia / Paradise
• Hot Spring® ACE® Salt Water Sanitizing System — the prior generation, found on older Hot Spring models

Compatible Spa Lines

• Hot Spring® Highlife® Collection — Salt System-equipped models
• Hot Spring® Limelight® Collection — Salt System-equipped models
• Caldera® Utopia® Series — Salt System-equipped models
• Caldera® Paradise® Series — Salt System-equipped models
• Older Hot Spring spas equipped with the ACE Salt Water System

Not Designed For

• Pool salt systems — pool salt concentrations run far higher (3,000–4,000 ppm typical), beyond this strip's range
• Non-salt spas — a chlorine, bromine, or biguanide spa has no salt to measure
• Detecting other water parameters — this strip only reads salt; use FreshWater 5-Way Test Strips for chlorine, pH, alkalinity, and hardness
• Other manufacturers' spa salt systems — those may use different salt concentration targets; check your spa's manual

Works Alongside

• FreshWater 5-Way Test Strips — for chlorine, pH, alkalinity, and hardness (essential paired test)
• FreshWater Spa Salt — for topping off salt when this strip reads low
• FreshWater Salt System Replacement Cartridge — proper salt levels extend cartridge life
• FreshWater Vanishing Act Calcium Remover — keeps calcium in range so the salt system operates efficiently
