Izayoi Hot Tub Replacement Cartridges for Frog Floating Dispenser — 3-Pack, SmartChlor mineral formula, lasts 3–4 weeks

If you own a small to medium hot tub and use a Frog-style floating dispenser, these Izayoi three-packs let you skip daily dosing and reduce overall chlorine use. Each cartridge contains a patented mineral and chlorine formula that slowly releases sanitizing agents while helping preserve soft water balance. They’re intended for tubs up to about 600 gallons and are an easy swap-in option when the floating system indicates replacement.

How long will one cartridge keep my hot tub balanced?

Each Izayoi SmartChlor cartridge is formulated to last roughly 3–4 weeks depending on tub size, bather load, and frequency of use. The release rate is self-regulating to maintain a steady low level of chlorine without routine adjustment.

• Typical life: 3 to 4 weeks per cartridge for average use
• Designed for tubs up to 600 gallons
• Higher use or larger tubs may shorten cartridge life

What maintenance is required when I use these cartridges?

Maintenance is minimal: insert the cartridge into your Frog floating dispenser and replace it when depleted. No mixing, measuring, or daily monitoring is needed, though regular testing of pH and alkalinity is still recommended for optimal water care.

• Insert into compatible Frog floating system — no refilling needed
• Replace every 3–4 weeks or as indicated by the dispenser
• Continue routine pH and alkalinity checks per manufacturer guidance

Will these cartridges reduce chlorine smell and harshness?

The Izayoi cartridges use a patented mineral technology that supports lower free chlorine concentration while maintaining sanitization. Many users report gentler-feeling water with less odor and reduced impact on skin, hair, and swimwear compared with higher-dose chlorine routines.

• Patented mineral blend helps stabilize low chlorine levels
• Formulated to be less harsh on skin and fabrics than heavy chlorine dosing
• Helps keep water clearer with consistent sanitizing activity

Are these cartridges compatible with my hot tub and floating system?

These replacement cartridges are made specifically for Frog-style floating dispensers and are suitable for most hot tubs up to 600 gallons. Verify your floating system model and tub capacity to ensure fit and expected performance.

• Made to work with Frog Ease floating dispensers
