FROG® Serene Bromine Cartridge | In-Line Spa Systems

Cartridges have been harder to find locally as a couple spa stores went out of business. Luckily they were in stock here online and priced same as local if not better with convenient shipping. They work well in the tub.

Worry free system. The purple cartridge last much longer than the yellow I was purchasing locally.

Leisure Time continues to be a reliable partner as I transition from an indoor swim spa, to an outdoor hot tub. Navigating new issues like the FROG inline sanitation system requires someone you can look to for support.
