If you are using FROG Serene®, then you know you have a Mineral Cartridge and a Bromine Cartridge, but you may be wondering why not a chlorine cartridge?
Both proven and effective sanitizers, here is a quick look at the differences between bromine and chlorine:
Must be hand-fed by the capful or spoonful into the water
Most often used in a floating device
How Often Needed
Usually every few days or after every use
Floaters need refilling every 1-2 weeks
Rate of Dissolution
Dissolves quickly in hot water, which can sometimes gas off, creating an odor
Slow dissolving for a steady output
Affected by Water Balance
Chlorine is very dependent on maintaining a neutral pH
Bromine will continue to perform even when pH is off
Odors are a sign the hot tub is in need of a shock treatment
Some odor is present when removing the cover but dissipates quickly
Shocks are used to break up combined chlorine that is then caught in the filter
Shocks regenerate the spent bromine into active bromine
This chart shows some of the areas where bromine outshines standard chlorine (dichlor):
Less work with a slow dispensing sanitizer that lasts for weeks
Less odor and a more effective technology that regenerates with shocking
Perfect for floaters like FROG Serene
FROG Serene takes using bromine to a new level
FROG Serene’s prefilled cartridges allow you to adjust and dial in the amount of bromine to meet your needs. With FROG Minerals, you can reduce your bromine use up to 50%.*
When it’s time to replace a cartridge, the Serene system tips on its side. There’s no need to measure and spoon in granules or add tablets to a floater by hand. That means no more wondering how much to add and no more worry about smelly hands or spilling chemicals. No mess, no guess, no stress. Just clean, clear Fresh Mineral Water®∞.
As the bromine is used up in your hot tub, it’s easy to revitalize with a shock, like our FROG Maintain® non-chlorine shock. Shocking simply regenerates used bromine into active bromine. FROG Maintain comes in a one-dose pouch – cut it open, pour it into your hot tub water, and in 5 minutes, it’s ready!
*Compared to the ANSI recommended bromine level of 2.0 ppm for spas.
∞For pools or hot tubs.
