The minerals inside the cartridge are designed to destroy bacteria, and reduce bromine use by up to 50%, improving the overall quality of the hot tub water.

The FROG Mineral Cartridge lasts for up to four months — or whenever you choose to refill your hot tub — and is ideal for hot tubs of 600 gallons or less. This product is used in combination with the FROG Bromine Cartridge resulting in Fresh Mineral Water® – soft feeling water that’s easier on skin, swimsuits and spa surfaces.
