FROG @ease In-Line SmartChlor Cartridge

The FROG @ease In-Line system is specifically designed for use with select hot tub models, including Hot Spring Spas, Marquis Spas, and Artesian Spas. Always verify that your spa is equipped with the factory-installed in-line housing before purchasing.

It uses SmartChlor technology, which maintains a consistent sanitizing level while using up to 75% less chlorine than standard systems. You will still need to shock the water monthly, but you won't deal with the harsh chemical spikes or strong odors associated with traditional chlorine.

Under normal usage conditions, each cartridge lasts up to four weeks. The exact lifespan can vary depending on your hot tub's usage frequency and water volume.

Yes. Because SmartChlor is significantly gentler than traditional chlorine, it is much less likely to cause the fabric fading, skin irritation, or strong chemical smells common with standard sanitization methods.

Maintenance is minimal. You simply need to perform a shock treatment once a month to keep the water balanced and clear. The in-line system handles the consistent sanitization automatically.
