The bottom line: this replacement reservoir is for anyone already using the Pool FROG 6100 system and looking to maintain cleaner, softer water with far less daily effort. Installation is straightforward, the reservoir is prefilled with FROG minerals, and it is intended to last a season, making it the single most convenient maintenance item for owners who prefer automatic, low-chlorine treatment.

Key Features

• Designed fit: Made to fit inside the Pool FROG Model 6100 Cycler so replacement is simple and aligns with the existing system.
• Prefilled convenience: Each reservoir comes prefilled with FROG sanitizing minerals so users can install and set the dial without manual mixing.
• Long service life: The mineral reservoir is intended to last up to 6 months or one pool season, reducing the frequency of replacements.
• Chlorine reduction: Using the mineral reservoir with Bac Pacs can reduce chlorine use by up to 50%, which leads to softer water that is gentler on skin and swimsuits.
• Complementary Bac Pacs: Works together with the included Pool FROG Bac Pac replacement chlorine cartridges, which last about 1 to 3 weeks for consistent sanitation.
• Proven technology: Built on more than 25 years of FROG water care know-how and patented mineral technology for reliable pool maintenance.

Who It's For

The FROG Model 6100 Mineral Reservoir is best for residential pool owners who already have the Pool FROG 6100 Cycler and want lower-maintenance sanitation with reduced chlorine levels. It suits families and frequent swimmers who prefer softer water that is easier on skin and swimwear and who value a seasonal, install-and-forget replacement approach.

It is not for pool owners who do not have the Pool FROG 6100 Cycler, or for those who want an all-in-one chemical program without Bac Pac chlorine cartridges. Those seeking instant heavy-duty shock treatment should look to specialized shock products instead of this seasonal mineral reservoir.
