Enjoying clean, clear swim spa water starts with the right sanitizer. One of the most common questions from swim spa owners (and retailers) is:
What should you use to sanitize a swim spa?
Answer: Products made to sanitize hot tubs or pools.
Many swim spa owners use pool or hot tub sanitizers, but those products weren’t specifically designed for swim spas. They often require frequent testing, measuring and adjustments to maintain proper water quality.
FROG® @ease® Sanitizing System for Swim Spas changes that.
The First Swim Spa Sanitizer
FROG® @ease® Sanitizing System for Swim Spas is the first and only complete sanitizing system purpose-built for the volume, temperatures and uses of swim spas.
The system includes FROG® @ease® Test Strips, making it easy to monitor your water and keep it within recommended ranges.
For best results, maintain the following water balance levels:
- Total Alkalinity: 80 – 120 ppm
- pH: 7.2 – 7.6
- Calcium Hardness: 150 – 250 ppm

Consistent Sanitization, Simplified
FROG @ease for Swim Spas keeps water clean and clear for up to four weeks, depending on swim spa size and usage.
Like any sanitizer, demand increases with use. A busy weekend, a family gathering or frequent workouts can introduce more contaminants into the water, causing sanitizer levels to be consumed more quickly.
With traditional chlorinating granules, this often means frequent testing and manually adding sanitizer after each use.
FROG @ease works differently.
Using a combination of FROG Sanitizing Minerals® and SmartChlor®, FROG @ease maintains a continuous low level of chlorine between 0.5 and 1.0 ppm. SmartChlor is self-regulating, releasing more chlorine when demand increases and less when demand decreases. The result is consistently clean, clear water whether your swim spa is in use or not.
Under typical use — just a few times per week — the SmartChlor Cartridge lasts up to four weeks, and the water only needs to be shocked once a month.
Easy to Set Up
Getting started with FROG @ease for Swim Spas takes just a few minutes:
- Remove the outer packaging from the Mineral Cartridge and locate the SmartChlor Cartridge.
- Snap the cartridges together until they click into place.
- Set the dial according to your swim spa’s gallon size (see the included manual).
- Attach the tether and let the system float in the swim spa.
That’s it.
