Frequently Asked Questions

  • The holder itself is designed to last for years with proper care. You'll only need to replace it if it becomes damaged or cracked. However, the SmartChlor cartridge inside should be replaced every 3-4 weeks, and the mineral cartridge every 4 months.
  • This specific holder (part #6473-315) is designed for 2021 and newer models. Sundance made design changes in 2021, so earlier models may require a different part number. Contact us with your spa's serial number, and we'll help you find the correct holder.
  • Genuine FROG holders are manufactured to exact specifications, ensuring proper fit, optimal water flow, and reliable sanitizer dispensing. Generic holders may not fit correctly, could leak, or may not dispense sanitizer at the proper rate, leading to water quality issues.
  • Yes, this listing is for the holder only. You'll need to purchase FROG @Ease SmartChlor and mineral cartridges separately. We carry complete FROG @Ease replacement cartridge packs at Hot Tub Things.
  • The SmartChlor cartridge will feel noticeably lighter when empty (typically after 3-4 weeks). The mineral cartridge should be replaced every 4 months. We recommend marking your calendar when you install new cartridges.
  • This holder is designed specifically for the FROG @Ease system. It's not compatible with other sanitizing methods. If you're currently using a different system, you'll need to transition fully to FROG @Ease for optimal results.
