Marquis SpaCare @ease with SmartChlor In-Line Refresh Kit

The Marquis SpaCare @ease with SmartChlor In-Line Refresh Kit is an easy water care kit for compatible Marquis spas using the in-line FROG @ease system. It helps maintain clean, clear spa water with a mineral cartridge and SmartChlor cartridges designed to work together inside the spa’s in-line sanitation system.

This kit is a convenient refresh option when starting fresh after a drain and refill or replacing your mineral cartridge and SmartChlor supply.

🔹 Key Benefits

  • Designed for compatible Marquis spas with the FROG @ease in-line system
  • Includes mineral and SmartChlor components for easier hot tub sanitation
  • Helps maintain a consistent low level of SmartChlor
  • Uses minerals plus SmartChlor technology to sanitize spa water
  • Can reduce the need for frequent chlorine measuring and handling
  • Great refresh kit after draining and refilling the spa

🧩 Compatibility & Fitment

This kit is intended for Marquis spas equipped with the compatible FROG @ease in-line sanitizing system.

Common compatibility includes:

  • Compatible Marquis spas using the in-line @ease system
  • FROG @ease in-line sanitizing systems for hot tubs up to 600 gallons
  • Systems that use the blue mineral cartridge and gray SmartChlor cartridges

❓ Frequently Asked Questions

Is this for Marquis spas?

Yes. This kit is intended for compatible Marquis spas using the in-line FROG @ease sanitizing system.

Is this the same as the floating FROG @ease system?

No. This kit is for the in-line system. Floating FROG @ease cartridges and in-line FROG @ease cartridges are not the same.

What comes in the kit?

The kit includes the mineral and SmartChlor components used with the in-line @ease system, plus startup items such as Jump Start and test strips.

How long does the kit last?

Usage depends on spa size, water temperature, bather load and water care habits. SmartChlor cartridges are replaced as they are used, while the mineral cartridge follows its normal replacement schedule.

Can I use regular chlorine test strips?

Use FROG @ease test strips for best results. SmartChlor reads differently than traditional chlorine, so standard strips may not give the right interpretation.
