How does FROG @Ease reduce chlorine and simplify maintenance?

The mineral cartridge delivers continuous mineral sanitization while SmartChlor supplies measured chlorine only as needed, lowering overall chlorine demand. Because minerals help control organics and condition water, you can use up to 75% less chlorine and shock far less often.

• Prefilled cartridge eliminates measuring and messy handling
• Reduces chlorine usage by up to 75% compared with chlorine-only routines*
• Shock only monthly or at drain/refill rather than after every use
• Minerals absorb acids and help maintain pH stability

What performance and water benefits can I expect?

Expect clearer water that feels softer on skin and hair because the minerals condition the water and help control contaminant load. The system is formulated to work together with SmartChlor for steady sanitizing power and predictable maintenance intervals.

• Minerals reduce organic contaminants for clearer water
• Conditioned water feels gentler on skin, hair, and swimwear
• Less frequent shocking saves time and reduces chemical handling
• Prefilled cartridge minimizes guesswork and installation mess

How do I install and maintain the cartridge safely?

Installation is straightforward when your hot tub includes the compatible in-line cartridge holder. Replace per the manufacturer’s recommended interval and always use SmartChlor tablets (sold separately) as directed to ensure the combined system works properly.

• Follow spa maker instructions for accessing the in-line cartridge slot
• Use only the recommended SmartChlor tablets with the FROG mineral cartridge
• Replace cartridge at the interval specified for your spa model
• Shock only monthly or at drain/refill as part of routine care

Who is this for: FROG @Ease in-line mineral cartridge is aimed at hot tub owners with compatible Artesian, Marquis, Caldera, or Hot Spring Hot Spot models who want a lower-chlorine approach and simpler, less frequent maintenance. It suits people who prefer prefilled, no-mess sanitizer solutions and expect soft-feeling water, predictable dosing, and time savings on routine care.
