This system has revolutionized hot tub water sanitation. The ions in these cartridges release as needed to eliminate bacteria + contaminants in the spa water and lower your chlorine/bromine consumption. Levels are adjustable based on the usage/size of your spa.
The mineral cartridge should be replaced every 4 months, roughly right around when you should be draining and re-filling your hot tub with fresh water.
- *Designed for specific spa models. Please check spa model compatibility before purchase.*
- Compatible with Caldera and Marquis hot tubs. These spas have built in holders for the Frog SmartChlor and Mineral Sanitizing Cartridges meaning all your sanitation happens inside the spas plumbing.
- Generally last about 4 months depending on spa usage/size
