FROG @Ease SmartChlor Replacement Cartridges are prefilled, self-regulating chlorine cartridges that fit the FROG @Ease Floating System and provide continuous low-level sanitation for swim spas up to 3,000 gallons.

Maintain clearer, gentler swim spa water with minimal fuss: these SmartChlor cartridges combine a patented chlorine formulation with FROG’s Mineral Technology to reduce overall chlorine demand and help keep pH balanced. Each cartridge is prefilled and engineered to release a steady, controlled amount of chlorine over several weeks so you don’t have to monitor or dose manually. This 3-pack ensures you have replacements on hand so the floating system can keep working cycle after cycle.

How long will each SmartChlor cartridge last in my swim spa?

Each cartridge typically lasts between three and four weeks depending on swim spa size, frequency of use, temperature, and bather load. Larger spas or heavy use will shorten life; smaller or infrequently used spas may see longer performance.

• Expected lifespan: about 3–4 weeks per cartridge
• Designed for swim spas up to 3,000 gallons
• Higher usage and heat increase consumption

How does SmartChlor reduce overall chlorine needs?

SmartChlor uses a patented low-dosage chlorine formulation that continuously dispenses a small, measured amount of sanitizer. Combined with FROG’s Mineral Technology—which helps reduce contaminants—the system typically allows you to use substantially less chlorine than standard dosing methods.

• Steady, low-level chlorine release minimizes spikes
• Mineral Technology helps shoulder part of sanitizing load
• Manufacturer guidance cites up to 75% less chlorine use versus conventional methods

Will these cartridges work without extra monitoring or testing?

SmartChlor cartridges are intended to be self-regulating and require no daily maintenance, but periodic water testing is still recommended to verify sanitizer and pH levels. The design eliminates frequent dosing; however, routine checks help ensure optimal water balance and cartridge performance.

• No daily cartridge adjustments required
• Periodic testing recommended for pH and sanitizer level verification
• Replace cartridges every 3–4 weeks or as use indicates

How do I install and replace a SmartChlor cartridge in the FROG @Ease Floating System?

Installation is straightforward: remove the spent cartridge from the floating unit and insert the new prefilled SmartChlor cartridge according to the floating system instructions. Dispose of the empty cartridge per local guidelines and always use genuine FROG replacement cartridges to maintain system performance.

• Slide out the old cartridge from the float housing
• Insert a new prefilled SmartChlor cartridge until seated
• Follow local disposal rules for used cartridges
