Generic Hot Tub Mineral & Prefilled Replacement Cartridge 1-Pack — Frog Ease compatible, self-regulating for up to 550 gal

These floating mineral and prefilled replacement cartridges keep hot tub water softer, clearer, and easier to balance while floating automatically in spas up to 550 gallons.

Keep your hot tub water comfortable and low-maintenance with a two-cartridge system engineered to work with the Frog Ease floating treatment platform. The package includes one long-life mineral cartridge and one prefilled replacement cartridge so you can start treating water immediately and continue maintenance without hunting for parts. Designed to float and self-orient as they deplete, these cartridges release conditioning minerals that help moderate pH changes and reduce harshness on skin, hair, and swimwear.

How long will each cartridge last and what affects longevity?

Cartridge life depends on spa size, bather load, and run time. The mineral cartridge delivers steady conditioning for months, while the prefilled cartridge is intended for shorter, more frequent replacement.

• Mineral cartridge: up to about 4 months in typical home use.
• Prefilled cartridge: up to roughly 4 weeks, varying by spa capacity and usage.
• Higher bather counts and larger volumes consume cartridges faster.
• Regular filtration and correct sanitizer levels help maximize life.

Will this work with my existing Frog Ease floating system?

Yes — the cartridges are sized and formulated to be compatible with the Frog Ease floating treatment platform found on many residential hot tubs. They install easily and float as the system operates.

• Designed to match Frog Ease cartridge dimensions and function.
• Slides into the floating system without tools.
• Floats upright during use and flips to signal empty status.
• Intended for spas up to 550 gallons; check your tub volume before buying.

What benefits can I expect for water feel and spa surfaces?

The mineral conditioner softens water sensation, helps protect swimsuit fabrics and reduces mineral-related buildup on hot tub surfaces. It works alongside your sanitizer to produce clearer, more comfortable water.

• Softer-feeling water that’s gentler on skin and hair.
• Helps limit scale and residue on shell and equipment.
• Aids in maintaining stable pH by conditioning the water matrix.
• Supports clearer water when combined with routine sanitation and filtration.

How do I install and know when to replace a cartridge?

Installation is tool-free: place the cartridge into the Frog Ease floater and set it on the water. The unit’s buoyancy keeps it working; once empty it will flip to indicate it needs replacement. Replace the prefilled cartridge on schedule and the mineral cartridge per its lifespan.

• Remove old cartridge, insert new one into the floating housing.
• Start with the 1-pack prefilled cartridge for immediate use.
• Watch for the floater to flip over as the replacement indicator.
• Follow spa manufacturer water chemistry guidance alongside cartridge use.
