* Compared to the minimum ANSI recommended chlorine level of 2.0 ppm for a hot tub
∞ Cleaner, Clearer and Softer water for pools, hot tubs and swim spas

Benefits

  • Enjoy softer water, reduced chlorine odors and water that's gentler on your skin
  • Mineral Cartridge lasts 4 months; SmartChlor Cartridge lasts 3-4 weeks
  • Innovative design floats when working, flips when it’s time to replace the SmartChlor Cartridge
  1. Connect the cartridges: Line up the arrows on both cartridges, push together and lock.
  2. Set the dial: Twist the dial on the SmartChlor® Cartridge to the setting number matching your hot tub (see the gallon chart in your manual).
  3. Place in the water: Let it free float, or use a tether to attach to the side of the hot tub.

Optional — remove while soaking: If you like, lift the system out while soaking and let it drain into the water. Set it on a surface not susceptible to chlorine bleaching and remember to return it afterward.

Replacing Cartridges

  • SmartChlor: Lasts about 3–4 weeks for an average 400-gallon hot tub. When the system flips completely over, remove and replace with a new one.
  • FROG Sanitizing Minerals®: Replace every 4 months or when draining/refilling — even if minerals appear to remain inside.

Frequently Asked Questions

The blue Mineral Cartridge lasts up to 4 months. The silver SmartChlor Cartridge typically lasts 3 – 4 weeks. When the SmartChlor Cartridge is depleted, the floater flips over, providing a clear visual cue that it’s time for replacement.

Keeping your hot tub balanced will extend the life of your SmartChlor Cartridge. Keep pH under 7.6. Over circulation, like being pulled into the filter well, will also deplete the cartridge faster. We recommend using a tether.

FROG @ease combines a proprietary mineral formula with SmartChlor Technology, a self-regulating sanitizer that maintains a consistently low and effective chlorine level for weeks.

Unlike traditional chlorine, which rapidly dissipates when people enter the water, SmartChlor automatically adjusts its output based on demand, preventing the fluctuating “yo yo” chlorine levels common in standard hot tub maintenance. This time release approach reduces chlorine use, minimizes odors, prevents faded swimwear and requires shocking only once per month—dramatically reducing maintenance.

Fresh Mineral Water∞ is our signature water quality experience — clean, clear and silky-soft water made possible by our patented mineral technology combined with significantly lower levels of chlorine. The result is water that’s gentler on skin and free from the harsh, over-chlorinated feel of traditional hot tub care.

1 FROG @ease Mineral Cartridge, 1 SmartChlor Cartridge, 1 FROG Jump Start® Packet and 30 FROG @ease Test Strips

FROG @ease kills bacteria by combining FROG Sanitizing Minerals® with SmartChlor Technology to create Fresh Mineral Water∞ that’s Cleaner, Clearer, Softer and Easier® to take care of.

Unlike standard dichlor, which spikes when added and drops when you use the tub, SmartChlor maintains a consistently low chlorine level of 0.5–1.0 ppm at all times. It self-regulates — delivering more chlorine when it senses demand and holding steady the rest of the time. That means no frustrating yo-yo chlorine levels, no constant monitoring and shock only once a month.

No. Use FROG @ease Test Strips only. Standard strips will show misleading readings with SmartChlor Technology.

Hot tubs with 150 to 600 gallons are perfect for FROG @ease.

With standard chemicals, you experience peaks and valleys in your sanitizing routine. When you add chemical, the level spikes. When you use the tub, the level drops. This yo-yo method goes away with FROG @ease because it maintains the same level of sanitizing from day 1 until the day the system flips over and it’s time to replace the SmartChlor Cartridge.

SmartChlor is a unique, patented type of chlorine. It will consistently maintain a 0.5 to 1.0 ppm chlorine level as long as the pH is balanced. This would not be enough on its own; but with FROG Sanitizing Minerals®, it’s a perfect combination that kills bacteria and creates Fresh Mineral Water∞ that’s cleaner, clearer and softer.

Yes. Set it on a bleach-safe surface and return it when you exit.

SmartChlor is slightly more expensive than dichlor but less than other systems. SmartChlor offers a nearly hands-off experience that automatically maintains consistent sanitizer levels, saving you time and guesswork while delivering clearer, more comfortable water with minimal effort. And with up to 75% less chlorine*, your suits won’t fade and your hot tub has less wear and tear.

Allan Knuutti

I purchased my hot tub a few months ago and ordered the floating Frog @ease system to start out with. It did a really nice job and was easy to use. I have since switched to your cartridge system since my hot tub came with that option. Love your product!

Ken Salvitelli

Product works great. Especially, if you disconnect your ozoneator. The ozoneator constantly depletes your chlorine reserves. Turn it off, and your Frog@ease can be set at 1 and work for at least 4 weeks. Depending on your bathe levels, your chlorine levels will maintain 1-3ppm! Don't care for the smell of di-chlor but, it is maintenance free sanitation. Owned Hot Tubs for nearly 30 years. How does it turn green? What are you doing?? Do you leave the cover off all summer long? Your gonna need to use shock then and maintain it like an outdoor pool.

David Smith

FROG® @ease® Floating System @ease® Floating System works very well. No fuss, no worries about pH levels. The product works as advertised and we have recommended the system to our fiends with hot tubs. They also have had success with FROG® @ease®.

Happy to hear this, Ray!

John Lauffer

The best way to a care free spa. Just put it in and it keeps the spa clean and comfortable. So much easier than guessing how much chlorine to add and when to add it. You can go away for a few weeks and it will keep everything clean and fresh.

Doug

We got our 1st hot tub last year and it has been so easy to maintain our hot tub. Used it several time this winter. It was the first time we had ever been in a hot tub while getting snowed on. Pretty cool. Got a pool after swimming weather, so looking forward to using frog in our pool this year.

Bill Robinson

Couldn't be easier to maintain our Hot Tub! I use less chemicals and the app takes all the guesswork out of what needs adding. I did have a question once – answer was fast and very helpful! 🙂

Bill Niles

Works great, will never have a hot tub without Frogease!

Craig A Schwegman

I am having difficulty getting the FCL below 1. I have reduced the setting on the smart Chlor from 4 to 3 with no change. This week I changed it to 2. Any suggestions?

FROG Products

Hi Craig! We want to help you troubleshoot this, but need more info from you to be of the best help. Could you call us or shoot us an email at 800-222-0169 or customer.service@kingtechnology.com? Thanks in advance!

I was a bit skeptical when I purchased the system but I am more than happy with the results. It's just so easy. I use to add my chlorine by hand but I always added too much or not enough so I was always chasing the perfect mix. Frog @ease has made that chase a reality and it's so easy that anyone can do it. Thank you for making my Hot Tub enjoyable again.

BONNIE K

I do like the Frog Ease system; however, it would be nice to be able to purchase the blue (mineral) half of the system without having to buy the entire set. I have plenty of the gray cartridges. It would be convenient to be able to buy just the mineral cartridge by itself when needed.

Thank you
