KEWINTANT hot tub mineral replacement cartridges 5-Pack for Frog @Ease — up to 600 gallons, pre-assembled

KEWINTANT replacement cartridges are pre-assembled, ready-to-use mineral cartridges made to fit the Frog @Ease floating system for hot tubs up to 600 gallons.

Keep your spa water balanced with a simple swap: these five replacement cartridges deliver consistent mineral dosing without complicated settings or daily checks. Each cartridge is designed to slide into the Frog @Ease floating dispenser and release minerals for 3–4 weeks depending on tub size and use. The pack gives you several months of coverage so you can focus on enjoying your hot tub rather than tracking consumables.

How do I install a KEWINTANT cartridge in my Frog @Ease floating system?

Installation is quick and tool-free. Open the floating dispenser, set the dial to the recommended position, drop the pre-assembled KEWINTANT cartridge into the unit, and return it to the water. The cartridge begins releasing minerals immediately.

• Pre-assembled cartridges—no assembly required
• Simple dial setting—one-step adjust for output
• Fits directly into Frog @Ease floating dispenser
• Works while the dispenser floats—no pump disconnection needed

How long will one cartridge last in my hot tub?

Each cartridge typically lasts 3–4 weeks, though actual life varies with tub capacity, bather load, and water chemistry. Larger tubs nearer the 600-gallon limit or heavily used spas will trend toward the lower end of that range. The five-pack provides continuous coverage across multiple months without frequent reorders.

• Estimated 3–4 weeks per cartridge under normal conditions
• Duration shortens with higher bather frequency
• Five cartridges supply several months depending on usage
• Replace sooner if water becomes cloudy or chemical readings change

Will these cartridges work with my hot tub and Frog Mineral Cartridge?

KEWINTANT cartridges are engineered for compatibility with the Frog @Ease floating system and the Frog Mineral Cartridge format, suitable for hot tubs up to 600 gallons. They are not intended for use with Flippin Frog pool floating systems; check your dispenser model before buying. If you have a non-Frog system, compare dimensions and mounting style first.

• Designed for Frog @Ease floating dispensers
• Safe for hot tubs up to 600 gallons when used as directed
• Not compatible with Flippin Frog pool systems
• Compare dispenser compatibility for non-Frog units

What maintenance should I expect when using KEWINTANT cartridges?

Maintenance is minimal: monitor water chemistry per your hot tub manufacturer’s recommendations and swap cartridges when output wanes or the preset time has passed. Cartridges arrive individually wrapped to protect freshness; just dispose of the used cartridge and insert a replacement. No daily dosing or complicated controls are required.

• No daily monitoring—periodic water testing still recommended
• Individual packaging preserves cartridge integrity
• Simple flip-and-replace operation reduces maintenance time
• Reach 24/7 customer support for product questions

Who is this for: KEWINTANT 5 Pack cartridges are aimed at hot tub owners who use the Frog @Ease floating system and want a low-effort mineral dosing solution for tubs up to 600 gallons. They fit users who prefer pre-assembled, easy-to-replace consumables that last weeks each and who appreciate an extended supply in one purchase. If you manage multiple spas or want fewer trips to reorder, this five-pack reduces interruptions and keeps your tub routine simple.

Note: Follow your hot tub manufacturer’s guidelines for water chemistry and safety. These cartridges are not intended as a replacement for regular testing and maintenance.
