Know before you buy
The device uses a mineral formula that works alongside a reduced amount of chlorine or bromine to kill bacteria. By integrating minerals into your filtration process, it provides a dual-action sanitizing effect that keeps your hot tub water cleaner and clearer.
The Frog Filter Mate is designed for use with most standard cartridge filters. Its one-piece design is adjustable, meaning you can shorten the stick if your specific filter cartridge is on the smaller side.
No, the Frog Filter Mate is not compatible with saltwater hot tub systems. It is intended for use in traditional hot tubs that rely on chlorine or bromine sanitizers.
The device features a built-in reminder dial that you set upon installation to track the four-month lifespan. You should also replace the unit whenever you perform a full drain and refill of your hot tub.
The Frog Filter Mate is not pH neutral, so you should continue to monitor your water chemistry as usual. You will still need to test and balance your pH and alkalinity levels regularly to ensure the minerals work effectively.
