Description

The FROG® @ease Swim Spa SmartChlor® Cartridge is the chlorine-generating cartridge built specifically for the FROG @ease Sanitizing System for Swim Spas. It’s the consumable half of the swim spa @ease pair — sized larger than hot tub cartridges to handle the much greater water volume of a swim spa, and engineered to release a steady, low level of self-regulating chlorine for weeks at a time.

Swim spa water care has its own challenges. With 1,500 to 3,000 gallons of water in play (versus the 150–600 gallons of a hot tub), the chlorine demand is higher, the math is harder, and the consequences of getting it wrong are bigger — you can’t just drain and start over the way you can with a hot tub. The @ease swim spa system was built to take that pressure off owners by automating sanitizing the same way @ease automates hot tub care: minerals plus a low, self-regulating level of chlorine, no daily dosing, no weekly shocking.

This cartridge is also one of the few you can actually see working. The housing is translucent gray, which means you can look at the cartridge and see the SmartChlor® inside — a visual cue that complements the floating system’s “flips over when empty” indicator. The chemistry is also cyanuric acid free, which matters in a large body of water like a swim spa where CYA buildup from traditional dichlor would gradually reduce sanitizer effectiveness over time.

Why Cyanuric Acid Free Matters in a Swim Spa: In a hot tub, you refill the water every 3–4 months — so CYA never gets a chance to build up. In a swim spa, you typically don’t drain that often (1,500+ gallons of hot, treated water is a major operation), so any CYA you add stays in the water for the long haul. Over months, a traditional dichlor program can push CYA high enough to start blocking your sanitizer from working. SmartChlor® sidesteps that entirely.
