The blue Mineral Cartridge last for 4 months. After that, most people choose to drain and refill their hot tub. Therefore, we packaged the new mineral cartridge with everything you need to start up a freshly filled hot tub.
When you refill your hot tub, you’ll need to balance your hot tub water with FROG @ease Test Strips and adjust as they indicate. Then add FROG Jump-Start to shock the water and insert your new Mineral Cartridge with a SmartChlor Cartridge in your holder custom designed for Bullfrog Spas.
The SmartChlor and Mineral Cartridges work together. The SmartChlor self-regulates with a low level of chlorine on demand.  It needs to be replaced when depleted – the “Out Indicator” on the FROG @ease Test Strips indicates this.
The Mineral Cartridge lasts for 4 months, and then the minerals are spent (even if you feel or hear them inside.)
Our goal was to make hot tub water care easier, that’s why all the products are included in one System box. You can be assured that you’ll have what you need when you refill your hot tub.
In between, you can purchase the 3-pack of SmartChlor Cartridges.
