The FROG® @ease SmartChlor® In-Line Kit is the complete starter package for the @ease In-Line System — the version of @ease that snaps directly into a port built into your spa's filter area rather than floating on the water. It includes both cartridges you need to start sanitizing right away: a mineral cartridge and a SmartChlor® cartridge, ready to drop into a compatible In-Line dispenser. If your spa came from the factory with an In-Line @ease port (a small cap, often near the filter compartment), this is the kit that brings it to life. Open the cap, snap in the cartridges, close it up, and you're done. From there, FROG handles the daily sanitizing work — releasing minerals and a low, self-regulating level of chlorine into the water as it circulates, automatically and continuously. The chemistry is purpose-built: SmartChlor® is a unique chlorine compound that works only with FROG® minerals. It self-regulates, delivering more free chlorine when your water demands it and pausing when the level is right. Together with the minerals, it sanitizes using up to 75% less chlorine than traditional water care, with no harsh chlorine smell, no daily dosing, and no weekly shocking. Why an In-Line System Matters: A built-in In-Line port is hidden, clean-looking, and out of the way — nothing floating in your spa for bathers to bump into. The cartridges sit inside the filter compartment, water flows through them on every circulation cycle, and the only thing you do is swap cartridges on their schedule. If your spa has the port, the In-Line approach is the most invisible way to run FROG @ease. Brand FROG®
