Includes 3 In-Line SmartChlor Cartridges

This replacement pack includes:

• 3 FROG @ease In-Line SmartChlor Cartridges

These cartridges are designed for use with the FROG @ease In-Line system and should be used with the compatible FROG @ease mineral cartridge. The mineral cartridge is sold separately unless included in a separate kit or bundle.

SmartChlor Technology with No Cyanuric Acid

FROG @ease SmartChlor is a unique chlorine technology designed to self-regulate by releasing chlorine as your hot tub needs it. Unlike traditional dichlor-based hot tub chlorine routines, SmartChlor helps maintain a steady low chlorine level without the frustrating spikes and drops that can make spa water harder to manage.

This product is positioned as a hot tub sanitizer with no cyanuric acid, making it a smart option for spa owners who want to avoid cyanuric acid buildup while keeping their water clean and comfortable.

For Hot Tubs up to 600 Gallons

FROG @ease In-Line systems are designed for compatible hot tubs up to 600 gallons. These cartridges are intended for spas that already have the built-in FROG @ease In-Line holder or cartridge system.

This is not a universal chlorine cartridge. Before ordering, confirm that your spa uses the FROG @ease In-Line system and not a floating FROG @ease system, Bullfrog-specific cartridge, Sundance-specific cartridge, filter snap-in cartridge, or another spa sanitizer format.

Designed for Select Marquis, Caldera, Artesian, and Hot Spring Spas

These FROG @ease In-Line SmartChlor cartridges are commonly used with select Marquis, Caldera, Artesian, and Hot Spring spas equipped with the built-in FROG @ease In-Line sanitation system.

Because spa compatibility can vary by model and year, always confirm your spa’s cartridge system before purchase. If your spa has the correct in-line FROG @ease holder, these SmartChlor cartridges are designed to install into that system and work with the matching FROG mineral cartridge.

Long-Lasting Cartridge Convenience

Each SmartChlor cartridge typically lasts about 3 to 4 weeks depending on hot tub size, water temperature, bather load, usage frequency, circulation, and water balance. With three cartridges included, this pack provides a convenient supply for multiple replacement cycles.

For best results, test your water regularly with FROG @ease test strips, replace the SmartChlor cartridge when indicated, and follow all manufacturer directions for cartridge installation, dial settings, water balance, and shock treatment.

Cleaner, Clearer, Softer Water with Less Work

The FROG @ease system combines FROG minerals with SmartChlor technology to help sanitize hot tub water using a low level of chlorine. When used as directed, the system is designed to reduce chlorine use, reduce frequent shocking, and help maintain more consistent water quality.

For spa owners who want easier hot tub water care, this 3-pack of replacement SmartChlor cartridges helps keep your in-line FROG @ease system ready for regular use.
