10 Best Hot Tub Chemicals 2025 in the United States

The FROG @Ease Floating System is a convenient sanitizer solution for hot tubs up to 600 gallons. It uses a combination of mineral cartridges and SmartChlor technology to keep water clean, soft, and well-sanitized with less chlorine odor and skin irritation compared to traditional chlorine products. The system is easy to use, floating in the water and signaling when cartridges need replacement—minerals every four months and SmartChlor every 3 to 4 weeks. Adding FROG Maintain monthly helps manage organic contaminants, supporting clear water and balanced sanitation.

The FROG @Ease Mineral Cartridge + SmartChlor Cartridges offer a convenient and efficient solution for maintaining a clean hot tub, suitable specifically for certain models like Artesian Elite, Marquis Crown, Caldera Vacanza, and Hot Spring Hot Spot, making it less versatile for other models. This product includes a mineral cartridge that lasts up to 4 months and three SmartChlor cartridges, each lasting 3-4 weeks, which is quite beneficial for extended maintenance without frequent replacement.
