Keeping hot tub water Cleaner, Clearer, Softer® shouldn’t be complicated — and with FROG @ease, it isn’t.

Here’s why hot tub owners everywhere are switching to FROG @ease:

  • Dual-Action Sanitizing Power: Combines SmartChlor® and FROG Sanitizing Minerals® to kill bacteria and create consistently clean water
  • Less Chlorine, More Comfort: Uses up to 75% less chlorine* for softer, gentler water
  • Smarter Chlorine: Automatically maintains ideal levels — no daily dosing or guessing
  • No Cyanuric Acid Build-Up: Prevents cloudy water and irritation caused by traditional chlorine
  • The Value of Fresh Mineral Water®∞: Enjoy luxurious, longer-lasting water with less effort

Let’s explore how FROG @ease works with your hot tub — starting with its dual-action sanitizing power.

Dual-Action Sanitizing Power

Most traditional chlorine systems rely on a single sanitizer to keep your water clean. FROG @ease is different. FROG Minerals and SmartChlor® sanitize together for cleaner water.

  • FROG Minerals are EPA-registered and proven to kill bacteria in hot tub water
  • SmartChlor® is a unique, self-regulating form of chlorine that maintains a consistently low level (0.5 – 1.0 ppm) instead of the harsh level (2.0 – 4.0 ppm) typical of standard chlorine systems

With FROG @ease there’s no daily testing and dosing, no constant measuring and no guesswork. Just Cleaner, Clearer, Softer® water with far less effort.

Less Chlorine, More Comfortable Water

Using less chlorine isn’t just good for your water — it feels better. With FROG @ease, you’ll notice:

  • Softer-feeling water that’s gentle on your skin and hair
  • No strong “chlorine smell” when you remove the cover
  • Hot tub surfaces and swimsuits that last longer without damage or fading
  • No more red eyes or itchy skin

Plus, your FROG @ease Mineral Cartridge only needs to be replaced every 4 months, continuously working to kill bacteria while you sit back and relax.

Smarter Chlorine

Traditional chlorine requires frequent measuring, testing and guessing. FROG @ease takes the guesswork out of hot tub water care.

  • SmartChlor automatically releases chlorine only when needed, maintaining the ideal level on its own
  • FROG @ease Test Strips make it even easier to test your water — just match one color to know when to replace your SmartChlor Cartridge. You’ll also get simple readings for Total Alkalinity, pH and Total Hardness
  • No confusing “Free” vs. “Total” chlorine levels to interpret — just straightforward, simple maintenance

Using FROG @ease in your spa helps you save both water and energy.

No Cyanuric Acid Build-up

Here’s a fact most hot tub owners don’t know: the CDC advises against using chlorine products containing cyanuric acid in spas and hot tubs. Traditional chlorine systems often contain up to 50% cyanuric acid, which builds up in your water over time — leading to irritation, odor, cloudiness and more frequent drains and refills.

FROG @ease contains no cyanuric acid, so your water stays clearer longer.

Great question! The best place to buy FROG products is through your local authorized FROG Dealer — they’ll ensure you get the right products and expert advice.

But if you don’t have a dealer nearby, you can also shop directly from our official FROG Amazon Brand Store for genuine FROG spa products delivered right to your door.

The Value of Fresh Mineral Water®∞

When you combine FROG Sanitizer Minerals with SmartChlor Technology, you get what we call Fresh Mineral Water®∞ — water that’s:

  • Cleaner – With minerals and a low level of chlorine
  • Clearer – No cyanuric acid build-up
  • Softer – Feels better on skin and hair
  • Easier – Less testing, less measuring, less hassle

You could stick to your current system and keep adding chlorine manually daily — but when you switch to FROG @ease you’ll enjoy a system that works smarter, not harder, to keep your hot tub clean.

For starters, we recommend you pick whether you like to sanitize with bromine or chlorine!

If you prefer bromine, FROG Serene is for you. If you prefer chlorine, FROG @ease is the best bet. Check out our Hot Tub Products tab for comparisons of our top spa products.
