FROG @ease In-Line Mineral Cartridge + 4 In-Line SmartChlor Cartridges - Free Shipping.

Easy Hot Tub Sanitizing for Built-In FROG @ease In-Line Systems

Keep your hot tub water cleaner, clearer, and easier to maintain with this FROG @ease In-Line Mineral Cartridge + 4 In-Line SmartChlor Cartridge bundle. Designed for hot tubs up to 600 gallons with a compatible built-in FROG @ease In-Line System, this bundle gives spa owners a convenient replacement set for ongoing mineral and chlorine-based water care.

The FROG @ease In-Line system uses FROG minerals and SmartChlor technology to help sanitize hot tub water with less routine maintenance than traditional chlorine methods. The cartridges install directly into the compatible in-line holder built into select Marquis, Caldera, Artesian, and Hot Spring spas.

Includes Mineral Cartridge + 4 SmartChlor Cartridges

This bundle includes:

• 1 FROG @ease In-Line Mineral Cartridge

• 4 FROG @ease In-Line SmartChlor Cartridges

The mineral cartridge supports the system’s mineral-based water care, while the SmartChlor cartridges provide self-regulating chlorine delivery. Together, they help maintain a consistent low chlorine level while reducing the need for frequent manual chlorine dosing.

Built for Compatible Marquis, Caldera, Artesian, and Hot Spring Spas

This FROG @ease In-Line bundle is designed for spas with the built-in FROG @ease In-Line cartridge system. Compatible spa brands may include select Marquis, Caldera, Artesian, and Hot Spring models that were manufactured with the FROG @ease In-Line system option.

This is not a universal hot tub cartridge set. Before ordering, confirm that your spa uses the FROG @ease In-Line System and not a floating FROG @ease system, filter-based cartridge, or a different in-line sanitation setup.

SmartChlor Technology for Easier Water Care

FROG @ease SmartChlor is designed to self-regulate by releasing chlorine as needed, helping reduce the “up and down” chlorine levels common with some traditional chlorine routines. When used with the FROG mineral cartridge, SmartChlor helps maintain a consistent low level of free chlorine for hot tub sanitation.

This system is also positioned as a cyanuric-acid-free hot tub sanitizer option, making it a helpful choice for spa owners who want to avoid adding cyanuric acid through traditional dichlor-based routines.

Long-Lasting Cartridge Convenience

The FROG @ease In-Line Mineral Cartridge typically lasts up to 4 months or until the hot tub is drained and refilled, whichever comes first. Each SmartChlor cartridge typically lasts about 3 to 4 weeks depending on spa size, water temperature, bather load, usage frequency, and water balance.

With four SmartChlor cartridges included, this bundle helps keep you stocked for multiple replacement cycles while the mineral cartridge supports longer-term mineral sanitation.

Cleaner, Clearer, Softer Hot Tub Water

The FROG @ease In-Line system combines sanitizing minerals with SmartChlor to help keep hot tub water cleaner, clearer, and softer-feeling. The system is designed to use less chlorine than ordinary hot tub sanitizing methods while still helping maintain safe, comfortable spa water when used as directed.

For best results, balance your spa water before installation, test regularly with FROG @ease test strips, replace SmartChlor cartridges when indicated, and follow all manufacturer directions for cartridge settings, water testing, and safe chemical handling.
