Simplicity cartridges have a rounded shape and install alongside flat, rectangular filters.\u003c\/p\u003e\n\u003ch4\u003eWill these cartridges fit every Bullfrog Spa?\u003c\/h4\u003e\n\u003cp\u003eNo. They only fit compatible Bullfrog Spas using the Classic cartridge holder.

The blue Mineral Cartridge is sold separately and must be used with SmartChlor.\u003c\/p\u003e\n\u003ch4\u003eHow long does each SmartChlor Cartridge last?\u003c\/h4\u003e\n\u003cp\u003eEach cartridge lasts approximately three to four weeks in an average 400-gallon spa. Actual life depends on spa size, temperature, bather load, filtration, water balance, and cartridge setting.\u003c\/p\u003e\n\u003ch4\u003eHow often should the Mineral Cartridge be replaced?\u003c\/h4\u003e\n\u003cp\u003eReplace the Mineral Cartridge every four months or whenever the spa is drained and refilled, whichever occurs first. The minerals are depleted after four months even if material can still be heard inside the cartridge.\u003c\/p\u003e\n\u003ch4\u003eWhy should I use FROG @ease Test Strips?\u003c\/h4\u003e\n\u003cp\u003eSmartChlor creates a sanitizer reserve that standard test strips may interpret as elevated total chlorine. FROG @ease Test Strips are designed for the system and include an Out Indicator showing when the SmartChlor Cartridge needs replacement.\u003c\/p\u003e\n\u003ch4\u003eDo I still need to shock the hot tub?\u003c\/h4\u003e\n\u003cp\u003eYes. Use FROG Maintain or another compatible non-chlorine MPS shock when replacing the SmartChlor Cartridge or approximately once per month.
