FROG SmartChlor Replacement Cartridge for Swim Spa — 1-Pack, Prefilled Low-Chlorine Sanitizer

FROG @Ease SmartChlor Replacement Cartridge is a prefilled, self-regulating chlorine cartridge made for the FROG @Ease Floating System to sanitize swim spas up to 3,000 gallons while supporting lower overall chlorine use.

Keep your swim spa water clear and balanced with a cartridge designed to simplify routine maintenance. The FROG SmartChlor cartridge combines a patented low-level chlorine formulation with FROG’s Mineral Technology so you can maintain continuous sanitization without constant monitoring. Each cartridge is prefilled and designed to last multiple weeks depending on spa size and usage, making it a straightforward swap-in solution for owners who already use the FROG @Ease floating sanitizing system.

How does the SmartChlor cartridge maintain sanitizer levels without daily checks?

The cartridge uses a self-regulating release mechanism that steadily dispenses chlorine at low concentrations essential for routine sanitation. Because it’s pre-calibrated, you won’t need to adjust feed rates manually from day to day.

• Prefilled cartridge — no mixing or measuring required
• Patented SmartChlor formula provides consistent, low-level chlorine
• Designed to release sanitizer over 3–4 weeks depending on usage
• Integrates with FROG @Ease floating system for hands-off operation

Will this cartridge reduce the amount of chlorine my swim spa needs?

The FROG SmartChlor design supports lower overall chlorine usage by maintaining a steady, minimal disinfectant level combined with FROG Mineral Technology. This approach helps reduce peak chlorine concentrations compared with frequent manual dosing.

• Supports up to 75% less chlorine use when used with FROG @Ease*
• Mineral Technology works alongside chlorine to enhance sanitization
• Lower chlorine levels are easier on skin, swimwear, and spa surfaces
• Consistent dosing avoids spikes and troughs in chlorine concentration

How long does a single cartridge last in a swim spa?

One SmartChlor cartridge typically lasts about three to four weeks, but actual life varies with swim spa volume and frequency of use. Larger, heavily used spas may require more frequent replacement than smaller or infrequently used setups.

• Estimated life: 3–4 weeks per cartridge
• Designed for swim spas up to 3,000 gallons
• Replace when cartridge is spent or performance drops
• Prefilled and disposable for quick replacement

How do I install a FROG SmartChlor cartridge with my floating system?

Installing the cartridge is straightforward: open your FROG @Ease floating system, insert the prefilled SmartChlor cartridge as directed, and place the floater in the swim spa. There’s no measuring, and no need to mix chemicals.

• Open FROG @Ease floater and insert cartridge per instructions
• Place floater in spa; system begins controlled release immediately
• No tools or dosing adjustments required
• Dispose of cartridge responsibly after use

Who this is for: The FROG @Ease SmartChlor Replacement Cartridge is ideal for swim spa owners who already use the FROG @Ease floating sanitizing system and want an uncomplicated, low-maintenance way to maintain safe water chemistry.
