Product Information

Frog Serene Bromine Cartridge

SPA FROG takes the thinking out of spa care with easy to set and replace cartridges. No measuring, no mess and no work for weeks at a time. The minerals destroy bacteria and help keep the pH in a safe range with less monitoring. A low 1.0 bromine level (50% less than most spas) finishes the job for a clean, clear spa ready to enjoy when you are.

In-Line Cartridge System

FROG Serene System is so popular spa brands have built it directly into their spas. It makes hot tub care even easier, and your hot tub experience even more luxurious. With FROG Serene, there’s no measuring out the right amount or constantly adding chemicals.  You simply replace your FROG Serene cartridges when used up and enjoy weeks of Fresh Mineral Water®.  That’s what FROG Serene provides with minerals and a low level of bromine that makes water feel softer and look crystal clear. 

Floating Cartridge System

Why limit the peace and serenity of a spa with second rate water care? The Spa FROG Floating System enhances a standard spa up to 600 gallons with its patented delivery of minerals and a low dose of bromine. Spa water stays soft without daily maintenance or the smells of chlorination. The Spa FROG Floater utilizes pre-filled mineral and bromine cartridges that snap into a reusable floating holder and works in any spa. The minerals last up to four full months, while the bromine can be dialed in to your precise needs, usually about three weeks per cartridge. Just snap the cartridges into the floating cap and relax!
