FROG @Ease SmartChlor Replacement Kit — 3-Pack Cartridges + Alkalinity Increaser & Maintain Shock for Hot Tubs, Controlled-Release

FROG @Ease Replacement Kit supplies three SmartChlor cartridges plus a Total Alkalinity Increaser and a Maintain shock so your hot tub stays continuously sanitized with minimal upkeep.

Keep hot tub water clear and comfortable without daily dosing or constant monitoring. This replacement bundle is built to work with the FROG @Ease floating system and mineral cartridge, delivering a steady low level of chlorine alongside mineral-based sanitization. The kit balances convenience with effective water management: prefilled SmartChlor cartridges release chlorine at a controlled rate while the alkalinity increaser and Maintain shock address pH stability and periodic oxidation needs.

How does this kit simplify hot tub maintenance?

The kit reduces hands-on maintenance by combining time-release chlorine cartridges with targeted chemical supports. SmartChlor cartridges are prefilled and self-regulating, eliminating daily chlorine measurement and frequent handling of concentrated chemicals.

• Three SmartChlor cartridges, each lasting 3–4 weeks depending on tub size and usage
• One packet of Total Alkalinity Increaser to help stabilize pH and prevent rapid swings
• One Maintain shock for routine oxidation and to refresh water clarity
• Designed to integrate with the FROG mineral cartridge for continuous mineral sanitization

What does SmartChlor do differently than standard chlorine?

SmartChlor uses a patented, controlled-release formula to keep a low, consistent chlorine level rather than large periodic doses. That steady output supports clear water while reducing the total chlorine required for routine sanitation.

• Maintains constant low-level chlorine for continuous sanitization
• Reduces overall chlorine usage—easier on skin and swimwear
• Prefilled cartridges remove the need to mix or measure liquid or granular chlorine
• Compatible with the FROG mineral cartridge for combined sanitizer action

When should I use the Total Alkalinity Increaser and Maintain shock?

The alkalinity increaser is intended when you measure low total alkalinity to help stabilize pH and prevent fluctuations. Maintain shock is a periodic oxidizer to clear contaminants, refresh water appearance, and assist the cartridge system after heavy use or before extended periods of bathing.

• Add alkalinity increaser when total alkalinity drops below recommended levels
• Use Maintain shock after parties, heavy bather loads, or every few weeks as a refresher
• Both products are provided in single-use quantities suited to typical hot tub maintenance
• Follow FROG @Ease instructions and test water regularly for best results

How long will a full replacement pack last in my hot tub?

Longevity depends on tub volume and usage frequency, but each SmartChlor cartridge is rated for roughly 3–4 weeks. With three cartridges plus the included shock and alkalinity packet, the pack generally covers about two to three months of routine use for most residential hot tubs.

• Each cartridge: approximately 3–4 weeks of service
• Three cartridges together: roughly 9–12 weeks of continuous chlorine delivery under typical conditions
• Actual time varies by tub size, temperature, and bather load
• Use test strips or kit to confirm sanitizer levels during use

Who is this for? The FROG @Ease Replacement Kit is aimed at hot tub owners who want consistent, low-maintenance water care and prefer prefilled, self-regulating cartridges over daily dosing. It’s a good fit for families, frequent entertainers, or anyone seeking gentler chlorine exposure for skin and fabrics while maintaining clear, balanced spa water. If you already use the FROG @Ease floating system and mineral cartridge, this pack provides the next step in routine upkeep with components tailored to that system.
