Izayoi Hot Tub Replacement Cartridges for Frog Ease Floating System — 3-Pack, 3–4 Week Mineral Sanitation for Tubs up to 600 gal

Izayoi replacement cartridges for the Frog Ease floating system provide three months of hassle-free, mineral-assisted hot tub sanitation that reduces chlorine demand.

These three-pack replacement cartridges are built to work with the Frog Ease Floating System to help keep hot tub water clear and comfortable with less frequent chemical dosing. Each cartridge releases minerals and a controlled amount of sanitizer over several weeks, eliminating daily monitoring and simplifying routine maintenance for tubs up to 600 gallons.

How long will one cartridge last in my hot tub?

Each Izayoi cartridge is formulated to provide steady, self-regulating treatment for approximately 3 to 4 weeks, depending on tub size and usage patterns. Heavy use or warmer water can shorten life; smaller, infrequently used tubs may see the longer end of the range.

• Typical life: 3–4 weeks per cartridge
• Best for tubs up to 600 gallons
• Heavier use reduces lifespan

Is installation difficult — will it fit my Frog Floating System?

Installation is straightforward: the cartridge is designed specifically for the Frog Mineral Cartridge configuration and the Frog Ease floating system. No tools or measuring are required—flip the floater, snap in the cartridge, and let the system work automatically.

• Tool-free, user-friendly setup
• Works exclusively with Frog hot tub floaters
• Not compatible with Flippin' Frog pool floaters

What does "self-regulating water treatment" mean for maintenance?

Self-regulating means the cartridge slowly releases minerals and a low-level sanitizer at a controlled rate so you don’t need to constantly test or dose the water. It simplifies maintenance tasks and reduces the frequency of manual chlorine additions while still supporting water clarity.

• Continuous, measured release of treatment agents
• Less frequent manual chlorine or shock dosing
• Minimal day-to-day monitoring required

Are there any safety or compatibility warnings I should know?

Yes. These cartridges are formulated only for Frog hot tub floating systems; do not use them in Flippin' Frog pool floaters or non-Frog devices. Always follow manufacturer instructions for storage, replacement intervals, and handling to keep treatment consistent and safe.

• Only for Frog hot tub floating systems
• Replace every 3–4 weeks as directed
• Store unused cartridges in a cool, dry place away from children and pets
