Description

The FROG® @ease System Cartridge Holder is the bracket that mounts the FROG @ease mineral and SmartChlor® cartridges onto your Sundance Spa’s primary filter. Without it, the @ease cartridges have nowhere to seat — so for a Sundance owner running the @ease system, the holder is the bridge between the cartridges you buy and the spa they need to live in.

Here’s the part that confuses most customers: this holder is built into most Sundance Spas built from 2021 onward. If you bought a newer 780, 880, or 980 series spa, your dealer likely installed the holder at delivery. In that case, you don’t need this product — you just need cartridges. This aftermarket holder is for older Sundance spas, replacement situations, or spas where the original holder is missing. A quick look at your filter area will tell you which camp you’re in.

The design itself is purpose-built for Sundance: the holder clips directly onto your spa’s primary filter cartridge and provides a stable position for both @ease cartridges to seat in. Water that’s already flowing through your filter passes through the cartridges on every cycle, delivering minerals and self-regulating chlorine without any new dispenser, floater, or port required.

Why a Built-In Holder Matters: Unlike a floating @ease dispenser that sits in the spa water and gets bumped by bathers, the holder mounts your cartridges out of the way alongside the filter. It’s invisible from inside the spa, doesn’t drift, and keeps the cartridges in the exact spot they need to be for proper water flow — the cleanest possible install of the @ease system on a Sundance.
