Spa Frog Mineral Cartridge

The Spa Frog Mineral cartridge works with either the Spa Frog Floating system or the in-line frog system used in Marquis Spas and Caldera spas. The silver ions in the cartridge eliminate bacteria and contaminants in the spa water, and lower your bromine consumption. The mineral cartridge should be replaced every 4 months, right around when you should be draining and re-filling your hot tub with fresh water.
