Features and water-care benefits

This spa-care accessory uses a patented mineral formula intended to help destroy bacteria while neutralizing acids that can affect pH.

Another practical advantage is its four-month lifespan, which makes planning replacements simpler. Instead of frequent product changes, spa owners can work the sanitizer into a routine water-care schedule and keep maintenance more predictable.

Fit, compatibility, and replacement notes

The Filter FROG stick is made to fit inside a pleated filter cartridge with a minimum filter core inside diameter of 1.5 inches.

This sanitizer replaces Jacuzzi ProClear and Leisure Time Mineral Purifier, which can be helpful when matching an existing maintenance routine or swapping to a comparable mineral-based system.
