The unique dual-action sanitizing system employed by this product kills bacteria through two different methods. Firstly, it utilizes a low level of chlorine, and secondly, it incorporates FROG Sanitizing Minerals. This combination allows the product to use up to 75% less chlorine* while maintaining a consistent low level of free chlorine in the water.

The FROG Sanitizing Minerals play a crucial role in conditioning the water, imparting a soft and balanced feel. They help keep the pH balanced and absorb acids, all while assisting in the elimination of bacteria and reducing the burden on the chlorine.

By employing this advanced sanitizing system, the product offers several key benefits. It maintains a consistent low level of free chlorine, which is ideal for hot tub users who prefer a gentler sanitizing approach. The FROG Sanitizing Minerals work in tandem with the chlorine to create a more balanced and user-friendly water environment.

The extended duration of the Mineral Cartridge and the FROG @ease SmartChlor Cartridges minimizes the need for frequent replacements, making this a convenient and cost-effective solution for hot tub owners. The product's ability to use up to 75% less chlorine* also contributes to a more enjoyable and comfortable hot tub experience.

Overall, this Mineral Cartridge and FROG @ease SmartChlor Cartridge set offers a comprehensive and effective solution for maintaining the cleanliness and balance of hot tub water. Its dual-action sanitizing system, water conditioning properties, and reduced chlorine usage make it an attractive choice for hot tub enthusiasts seeking a more user-friendly and sustainable water treatment option.
