Simplify hot tub water care with the FROG Serene Floating System Kit, an easy-to-use mineral and bromine sanitizing system designed to keep spa water clean, clear and comfortable with less day-to-day chemical handling. Instead of measuring bromine every time your hot tub needs sanitizer, FROG Serene uses convenient pre-filled cartridges that snap into a floating holder and continuously treat the water.
The FROG Serene system combines a Mineral Cartridge with an adjustable Bromine Cartridge to destroy bacteria in two ways. Because the minerals provide part of the sanitizing work, FROG says the system can reduce bromine use by up to 50% compared with the minimum ANSI-recommended bromine level for a residential hot tub. That means effective sanitation with a lower bromine level, helping create softer-feeling water with less sanitizer odor.
Once installed, the system simply floats in your hot tub and continuously dispenses sanitizer. The Mineral Cartridge lasts four months or until the spa is drained and refilled, while each Bromine Cartridge typically lasts 2–4 weeks depending on hot tub size, use and cartridge setting.
The adjustable design also lets you fine-tune bromine delivery for your spa. FROG recommends maintaining a bromine level of 1.0–2.0 ppm when using the system and adjusting the cartridge as necessary based on regular water testing.
Why Choose the FROG Serene Floating System?
Up to 50% less bromine: FROG minerals work with bromine to provide effective sanitation while reducing the amount of bromine required.
No daily measuring: Pre-filled cartridges reduce the mess and guesswork associated with manually measuring sanitizer.
Long-lasting mineral cartridge: The Mineral Cartridge lasts four months or until the spa is drained and refilled.
Adjustable bromine delivery: Set the Bromine Cartridge according to your hot tub size, then fine-tune it based on your test results and usage.
Softer-feeling water: Using less bromine helps provide water that feels softer on skin, swimsuits and spa surfaces.
Made for a wide range of spas: FROG recommends the Serene Floating System for hot tubs from 150 to 600 gallons.
Easy cartridge replacement: When a cartridge is depleted, simply remove it from the floating holder and install a replacement.
For hot tub owners who prefer bromine but want an easier way to maintain their water, the FROG Serene Floating System Kit offers a convenient combination of effective sanitizing, lower bromine use and simple cartridge-based maintenance.
