Frequently Asked Questions
Your local Sundance Spas dealer will carry the product that has Sundance Spas right on the carton. These cartridges are also the same as the FROG @ease for Jacuzzi Hot Tubs and FROG @ease 2-in-1 Water Care cartridges if needed.
SmartChlor Technology offers a self-regulating sanitizer that maintains a consistently low and effective chlorine level for weeks.
Unlike traditional chlorine, which rapidly dissipates when people enter the water, SmartChlor automatically adjusts its output based on demand, preventing the fluctuating “yo yo” chlorine levels common in standard hot tub maintenance. This time release approach reduces chlorine use, minimizes odors, prevents faded swimwear and requires shocking only once per month—dramatically reducing maintenance.
With standard chemicals you experience peaks and valleys in your sanitizing routine. When you add more sanitizer, the level spikes. When you use the tub, the level drops. This yo-yo method goes away with FROG @ease because it maintains the same level of sanitizing from day 1 until the day the system flips over and it’s time to replace the SmartChlor Cartridge.
No, SmartChlor won’t work properly by itself. It must be used with FROG Sanitizing Minerals to properly sanitize your hot tub and maintain the low free chlorine level of 0.5-1.0 ppm..

Use the FROG @ease Test Strips to see if the color block on the test strip is lighter or darker than the purple block on the bottle label. If lighter, it is time to replace the cartridge.
Keeping your hot tub balanced will extend the life of your SmartChlor Cartridge. Keep pH under 7.6.
No. Use FROG @ease Test Strips only. Standard strips will show misleading readings with SmartChlor Technology.
