FROG® @ease Replacement Cartridges are the consumable heart of the @ease Floating Sanitizing System — the simplest, lowest-maintenance way to keep a hot tub clean. This 3-pack contains the SmartChlor® and mineral cartridges that snap into your existing @ease floating dispenser and do the daily work of sanitizing your spa for you, automatically, between water changes.

If you own a hot tub, you already know the real cost isn't the water care products — it's the time and guesswork. Test, dose, wait, retest, shock, repeat. The @ease system was built to take that off your plate. Instead of manually adding chlorine and chasing a moving target, the system continuously releases a low, steady level of sanitizer using SmartChlor® Technology — a self-regulating chlorine that activates only when your water needs it. The result is water that stays clean and clear with up to 75% less chlorine than traditional systems, no harsh chlorine smell, and far less hands-on maintenance.

These are the genuine FROG® cartridges sized specifically for Bullfrog Spas, so they drop into the Bullfrog @ease dispenser without adapters or workarounds. Keeping a fresh 3-pack on hand means you're never caught with cloudy water and an empty dispenser — you simply swap in the next cartridge when the indicator tells you to.
