The Bromine use in your spa is cut by up to 50% with the spa frog minerals in the water. This means less irritation, softer water and no more smelly chemical odours. 

Spa Frog bromine cartridges can be replaced easily if you have the in-line system already built into your spa. This is done by twisting the spa frog cap on top of your tub, pulling the holder out, discarding the old spa Frog cartridge and then replacing with the full one. 

The Spa Frog bromine cartridge lasts between 2-4 weeks depending on use. It is recommended to maintain at least 1.0 ppm bromine level in the water.
