FROG @ease In-Line SmartChlor Replacement Chlorine Cartridge, 1 Pack

Single-Cartridge Refill for Your FROG @ease In-Line Spa System

Refresh your hot tub water care routine with a single FROG @ease In-Line SmartChlor Replacement Chlorine Cartridge. This 1-pack refill is a convenient choice when your current cartridge is ready to be replaced, when you want to keep one backup cartridge on hand, or when you need a quick replacement for your compatible in-line FROG @ease hot tub system.

Designed for hot tubs up to 600 gallons, this SmartChlor cartridge works with FROG minerals to help maintain cleaner, clearer, softer-feeling water with less hands-on maintenance than traditional hot tub chlorine routines.

Ideal for a Quick Replacement or Backup Supply

A 1-pack is perfect when you do not need a larger multi-pack but still want to avoid interrupting your spa care schedule. Keep one cartridge nearby so you are ready when your FROG @ease test strip indicates that the SmartChlor cartridge needs to be replaced.

This individual replacement format is especially useful for occasional hot tub users, seasonal spa owners, or anyone who wants a single FROG @ease In-Line SmartChlor refill without buying a bundle.

SmartChlor Technology with No Cyanuric Acid

FROG @ease SmartChlor is designed to self-regulate, releasing chlorine as your hot tub needs it. This helps maintain a steady low chlorine level and reduces the frustrating ups and downs that can happen with some traditional chlorine maintenance routines.

Because SmartChlor is a hot tub sanitizer with no cyanuric acid, it helps avoid cyanuric acid buildup that can make spa water harder to manage over time. It is a strong option for spa owners who want cleaner water, lower chlorine levels, and a more consistent hot tub maintenance routine.

For Compatible In-Line Systems in Hot Tubs up to 600 Gallons

This replacement cartridge is made for hot tubs equipped with the FROG @ease In-Line system. It is commonly used in select Marquis, Caldera, Artesian, and Hot Spring spas that include a built-in FROG @ease In-Line cartridge holder.

This is not a universal spa chlorine cartridge. Before ordering, confirm that your hot tub uses the in-line FROG @ease cartridge system and that you also have the compatible FROG @ease mineral cartridge installed.

Helps Maintain Consistent Low-Chlorine Water

The FROG @ease system pairs FROG minerals with SmartChlor to help sanitize water using a consistent low chlorine level. The SmartChlor cartridge typically lasts about 3 to 4 weeks, depending on spa size, water temperature, bather load, circulation, and usage.

With routine testing and proper water balance, this cartridge helps keep your hot tub ready with less frequent manual dosing and fewer maintenance steps.

Cleaner, Clearer Spa Water Without the Big Chemical Routine

If you want a simple way to maintain your hot tub without constantly adding chlorine, the FROG @ease In-Line SmartChlor 1-pack gives you a convenient replacement cartridge that fits directly into your compatible in-line system.

Use it as part of your regular FROG @ease routine to help support fresh, balanced, comfortable spa water for everyday soaking.
