FROG ease SmartChlor Replacement Cartridges

No, these specific cartridges are designed exclusively for use with Bullfrog Spas Classic models that utilize the FROG ease system. They will not function correctly in other spa brands or systems.

The lifespan of a cartridge typically depends on your spa usage and water volume, but generally, one cartridge lasts between three to four weeks. You will know it is time to replace it when the cartridge flips over, indicating it is empty.

The FROG ease system is designed to be a complete sanitizing solution, so it significantly reduces the need for traditional chlorine. However, you should still periodically test your water balance—specifically pH and alkalinity—to ensure the sanitizer works effectively.

SmartChlor maintains a consistent, low level of chlorine that is gentler on skin, swimwear, and spa surfaces. It automatically releases sanitizer as needed, which helps prevent the sharp chemical smell often associated with traditional chlorine treatments.

This 3-pack contains only the SmartChlor replacement cartridges. It does not include the mineral cartridge or the floating holder system required for the full FROG ease setup.
