FROG® Water Care System

The FROG System* is bromine-based and is formulated to work effectively in warm water. The system is integrated into the shell of the spa.

Available on all Vacanza Series Spas.

How it Works

The FROG water care system makes hot tub water treatment amazingly simple. There’s nothing to measure or pour. Simply dial in your use level on the bromine cartridge and insert it into the integrated housing. Other than testing your water weekly, that’s all you need to do! The FROG system will continually keep your water crystal clear. The system uses fewer chemicals than traditional systems and contains bromine that is gentler on your skin. Treating your hot tub with bromine also eliminates the harsh smell associated with chlorine sanitisers. * This system is approved for use in the following countries: Austria, Denmark, France, Germany, Ireland, Italy, Norway, Portugal, Sweden, UK.

FROG Replacement Cartridges

Available only from Caldera Spas dealers, our custom FROG bromine cartridge contains 150 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 monthly to maintain sparkling clear water. (With regular use. Varies by spa size.)
