King Technology Spa FROG Serene Mineral Cartridge | 01-14-3812
The ultimate foundation for a truly relaxing, odor-free hot tub experience. The King Technology Spa FROG Serene Mineral Cartridge (01-14-3812) is the essential blue purifying component engineered specifically for use in factory-installed Spa FROG In-Line plumbing systems and Spa FROG Floating Dispensers. Utilizing a highly effective, EPA-registered blend of natural minerals, this cartridge actively destroys bacteria and neutralizes contaminants in spas up to 600 gallons, working continuously behind the scenes to keep your water crystal clear.
By harnessing the power of active minerals, the Serene system handles a massive portion of the sanitizing heavy lifting. This allows you to drastically reduce your hot tub’s reliance on harsh traditional chemicals, cutting your necessary bromine or chlorine levels by up to 50%. The result is "Fresh Mineral Water" that feels remarkably silky on the skin, completely eliminating the dry, itchy irritation, faded swimsuits, and overpowering chemical smells associated with standard hot tub maintenance.
Features
Powerful Mineral Purification: Contains a proprietary, EPA-registered blend of silver and other active minerals. As water flows through your system, these minerals are steadily released to actively neutralize harmful bacteria and keep your spa water pristine and safe for soaking.
Dramatically Reduces Chemical Use: Because the natural minerals are constantly fighting off contaminants, your hot tub requires a significantly lower sanitizer residual (as low as 1.0 ppm of bromine or chlorine) to stay perfectly balanced. This translates to a much healthier, more comfortable soaking environment.
Versatile Compatibility: Designed to click perfectly into both factory-installed Spa FROG In-Line systems (commonly found tucked into the shells of major hot tub brands like Caldera, Marquis, and Hot Spring) as well as the standard tethered Spa FROG Floating Dispenser.
Extended 4-Month Lifespan: Enjoy months of hands-free water care. A single blue mineral cartridge is engineered to last for a full four months. A convenient dial is built directly into the cartridge, making it easy to set a physical reminder of exactly when it is time to swap it out.
Synergistic Water Care: Engineered to work perfectly in tandem with the Spa FROG yellow bromine cartridges or green SmartChlor cartridges, creating a complete, highly effective two-part water care system that completely eliminates the need for measuring messy powders or handling loose tablets.
