FROG Mineral + SmartChlor Cartridge Kit for Marquis/Caldera/Hot Springs — 4‑Month Mineral + 3 Chlorine Cartridges for up to 600 ga

FROG @Ease Mineral Cartridge plus SmartChlor Cartridges is a cartridge-based hot tub sanitizing system that combines mineral sanitizers with a low, consistent dose of chlorine to control contaminants in spas up to 600 gallons.

Designed for select Marquis, Caldera, Artesian and Hot Springs models, this set pairs a four-month mineral cartridge with three replaceable SmartChlor cartridges so you get continuous mineral sanitation plus controlled chlorine relief. The system reduces reliance on free chlorine by using FROG Sanitizing Minerals to help manage organic load, condition water for a softer feel, and keep sanitizer levels more stable over time. Cartridges are simple to install in compatible spa heads and are sized to support typical household hot tub use without daily dosing.

Which hot tubs is this cartridge system compatible with?

The FROG @Ease kit is intended only for specific hot tub heads and models; confirm compatibility before ordering. It fits Artesian Elite, Artesian Island (and optionally on Artesian Island Elite and South Seas), certain Marquis Crown units (and optionally Marquis Elite, Vector and Celebrity), Caldera Vacanza, and Hot Spring Hot Spot spas. Using an incompatible model may prevent proper cartridge seating or dosing.

• Artesian Elite and Artesian Island models supported
• Compatible with certain Marquis Crown and optional Marquis Elite/Vector/Celebrity
• Designed for Caldera Vacanza and Hot Spring Hot Spot
• Check your spa manual or the hot tub head for FROG cartridge compatibility

How long do the mineral and SmartChlor cartridges last?

The mineral cartridge provides up to four months of continuous mineral release before replacement is needed, while each SmartChlor chlorine cartridge lasts roughly three to four weeks depending on tub size and use. Replacement intervals vary with bather load, temperature and filtration cycles; heavier use shortens cartridge life. Keeping the system topped up ensures steady sanitizer levels and more even water quality.

• Mineral cartridge life: up to 4 months
• SmartChlor cartridge life: about 3–4 weeks each
• Durability depends on gallons, usage frequency and water temperature
• Monitor free chlorine and replace cartridges promptly when depleted

What does this system do differently from standard chlorine-only care?

FROG combines trace minerals with a low, controlled dosing of chlorine so you rely on far less chlorine overall. The minerals help reduce organic contaminants, soften the water feel, assist with pH stability, and ease the sanitizer workload. SmartChlor cartridges deliver a constant, measured chlorine output rather than large, fluctuating shock doses, which makes maintenance simpler for many owners.

• Uses up to 75% less chlorine compared with traditional methods*
• Minerals help neutralize organic matter and condition water
• Maintains a consistent low free chlorine level for ongoing sanitation
• Reduces the need for frequent manual chlorine additions

How do I install and maintain the cartridge set in my hot tub?

Installation is straightforward: place the mineral cartridge into the spa head per your hot tub’s instructions, then insert the SmartChlor cartridges into their designated housing. Periodically check cartridge condition, refill or replace SmartChlor when empty, and swap the mineral cartridge every four months. Maintain basic spa care—filter cleaning, water testing and occasional shock treatments as recommended by your manufacturer—to support the cartridge system.

• Install mineral cartridge into compatible spa head slot
• Insert SmartChlor cartridges into the chlorinator housing
• Replace SmartChlor every 3–4 weeks; mineral every 4 months
• Continue routine water testing and filter maintenance

Who is this for? This FROG cartridge bundle suits spa owners of the listed Marquis, Caldera, Artesian and Hot Springs models who want an easier, lower-chlorine routine without changing the entire sanitation system. It's a practical choice for households seeking softer-feeling water, steadier sanitizer readings, and fewer daily treatment chores. Verify your spa model's compatibility, follow manufacturer instructions for installation, and keep a regular testing schedule for best results.
