Which hot tubs and spa models will these cartridges fit?

These cartridges are intended for spas that accept the Frog @Ease in-line SmartChlor mineral cartridge and hold up to 600 gallons. They fit specific models across several makers; verify compatibility with your spa’s manual or existing cartridge housing before buying.

• Compatible models include select Artesian, Marquis, Caldera, and Hot Spring spa lines.
• Designed for hot tubs with capacities up to 600 gallons.
• Meant to replace the in-line SmartChlor mineral cartridge, not floating units.

How long does each cartridge keep my spa water clear?

Each cartridge provides consistent performance for about 3–4 weeks under normal use and maintenance. Replacement frequency depends on bather load, water temperature, and spa chemistry; higher use or warmer temperatures can shorten cartridge life.

• Typical replacement cycle: every 3–4 weeks.
• Monitor chlorine and pH regularly to ensure optimal performance.
• Keep spare cartridges on hand to maintain uninterrupted protection.

What water-care benefits do these cartridges offer?

Lisyee cartridges combine mineral media with slow-release SmartChlor to help soften water and maintain clarity while lowering the total chlorine needed. They are designed to work with your existing sanitation routine, not replace routine testing and balancing.

• Slow-release SmartChlor aims to reduce free chlorine demand while sanitizing.
• Mineral media can improve water feel and help reduce harshness.
• Helps maintain clearer-looking water with less daily chemical adjustment.

How easy is installation and maintenance?

Installation is straightforward: insert the Lisyee cartridge into your spa’s in-line SmartChlor housing per manufacturer instructions. Routine upkeep remains the same—test water chemistry regularly and swap cartridges on the recommended schedule.

• No special tools required for standard in-line cartridge replacement.
• Follow your spa manufacturer’s placement and orientation guidance.
• Dispose of used cartridges responsibly and replace as scheduled.

It’s a practical choice for people with compatible Artesian, Marquis, Caldera, or Hot Spring models up to 600 gallons who prefer predictable 3–4 week cartridge changes, a gentler water feel, and fewer daily chemical adjustments.
