Spa Frog is a hot tub water care system that uses bromine and mineral cartridges to improve water quality, reduce the need for chlorine, and eliminate daily maintenance. The blue cartridge in the Spa Frog system is responsible for mineral sanitisation. It contains natural minerals that help to: Kill bacteria and inhibit algae growth in the water. Enhance water quality by reducing the need for higher levels of chlorine or bromine. Create softer-feeling water, making your soak more comfortable and gentle on your skin. When used alongside the yellow bromine cartridge, the blue cartridge works as part of a dual sanitising system to keep your spa water clean and clear while reducing chemical odours and potential irritation. It typically lasts for about 4 months, depending on your spa usage and water care routine.
