Description
The Frog Serene Chemical Bundle includes the supplies you need for a full season or more of fresh, pure mineral water for your hot tub or swim spa. This set of four cartridges refills the Serene In-Line System or the Serene Floating System. These systems were previously known as the Spa Frog In-Line Sanitizing System or the Spa Frog Floating System. The size, quality, and formulation have not changed. All that has changed is the addition of the brand name "Serene." Please note that these are genuine, King Technology brand refills. You must already have the green floating frog or an inline-dispenser in your hot tub.
