2 Spa Frog Inline Bromine Cartridge System
The FROG integrated water care system is available for all the Caldera line of Hot Tubs and makes hot tub water treatment amazingly simple. There’s nothing to measure or pour. Simply dial in your use level on the bromine cartridges and insert them into the integrated housing. The FROG system will continually keep your water
FROG Replacement Cartridges
Available only from Caldera Spas dealers, our custom FROG bromine cartridge contains 200 grams of bromine so it lasts longer than standard FROG bromine cartridges and is designed specifically for the water needs of Caldera Spas hot tubs. Replace bromine cartridges approximately every month depending on usage and spa size.
Caldera Ozone System RECOMMENDED with this System
The optional high-output Caldera Corona Discharge (CD) ozone system reduces the need for hot tub chemicals by continuously mixing highly concentrated ozone into the water. This system works efficiently with the FROG inline system, reducing the amount of chemicals required to maintain fresh, clean and clear spa water.
