FROG® @ease® Systems

Cleaner, clearer, softer water with up to 75% less chlorine — and a lot less work. FROG® @ease® pairs FROG® Minerals with patented SmartChlor® Technology to sanitize two ways and hold a steady chlorine level, so there are no frustrating peaks and valleys. Choose the built-in In-Line System or the drop-in Floating System.

Why Owners Switch to FROG® @ease®

SmartChlor® is a patented, self-regulating form of chlorine that only works alongside FROG® Minerals — together they keep water consistently sanitized at a fraction of the chlorine.

Up to 75% Less Chlorine

Minerals do much of the sanitizing, so SmartChlor® only needs to hold a low, steady level — no yo-yo chlorine swings.

Shock Just Once a Month

Self-regulating sanitizing means far less routine — a single monthly shock keeps water clear.

Softer Water, Less Odor

FROG® Minerals create Fresh Mineral Water® that feels silky on skin and is gentler on eyes and swimsuits.

Built-In Convenience

FROG® @ease® In-Line System

Built into select hot tubs, the In-Line System is the most convenient way to run @ease®. Open the cap on your spa, snap in the Mineral and SmartChlor® cartridges, and enjoy weeks of cleaner, clearer, softer water — with nothing floating in the water.

  • Cartridges seat in your spa's built-in holder, tucked neatly out of sight
  • Adjustable setting fine-tunes output to your spa size and how often you soak
  • The @ease® Test Strip's Out Indicator shows exactly when to swap the SmartChlor® cartridge
  • Mineral cartridge lasts about four months — roughly one per drain and refill

Drop-In Simplicity

FROG® @ease® Floating System

The quick, easy way to add FROG® @ease® to almost any hot tub — no built-in holder required. Drop it in and let it work. When the SmartChlor® cartridge is used up, the whole system flips over as a visual reminder that it's time to replace it.

  • Fits nearly any hot tub from 150 to 600 gallons
  • Flips over when the SmartChlor® cartridge needs replacing — no guesswork
  • Lift it out while you soak, then drop it back in when you're done
  • Same mineral + SmartChlor® water quality as the In-Line System

How SmartChlor® Technology Works

Two sanitizers working together mean less chlorine, less effort, and water that stays consistent between soaks.

1

Minerals Condition & Sanitize

FROG® Minerals go to work continuously, handling much of the sanitizing load so far less chlorine is needed.

2

SmartChlor® Self-Regulates

Instead of spiking and crashing like a manual dose, SmartChlor® holds a low, steady free chlorine level and releases more only when your water demands it.

3

You Test in Seconds

A single @ease® Test Strip confirms your water balance and tells you when the SmartChlor® cartridge is ready to be replaced.

FROG® @ease® FAQs

What size hot tub does FROG @ease work in?

Spas from 150 to 600 gallons — which covers the large majority of residential hot tubs. Not sure of your volume? Send us your brand and model and we'll confirm.

Which system should I choose?

If your spa was built with an @ease® cartridge holder, the In-Line System is the tidiest option. If it wasn't, the Floating System gives you the same water quality in any compatible tub.

How long do the cartridges last?

The Mineral cartridge runs about four months, or until your next drain and refill. The SmartChlor® cartridge typically lasts a few weeks, depending on spa size, temperature, and how often you use it.

How is this different from chlorine or bromine tablets?

Standard sanitizers give you peaks and valleys — high right after dosing, low by the time you soak again. @ease® is designed to hold a consistent low level of free chlorine at all times.

Can I still use my hot tub while the system is in the water?

Yes. With the Floating System, many owners lift it out during a soak and drop it back in afterward. The In-Line System stays in place.
