FROG @Ease Floating System for Hot Tubs
The FROG @Ease system offers a self-regulating sanitizing solution with SmartChlor technology. The floating system stays in the tub, automatically releasing minerals and chlorine as needed for up to four months with three additional SmartChlor Cartridges.

This kit emphasizes consistent water quality with minimal daily effort.

The included test strips help monitor ongoing water quality to maintain a safer soak.
SpaGuard Chlorinating Concentrate

It is designed to be compatible with various sanitizers, including chlorine, bromine, ozone, and mineral or UV systems, supporting flexible spa care routines.
Buying Guide: Key Purchase Considerations
When selecting hot tub and spa care products, consider the following:
- Water balance versus sanitization: Decide whether you prioritize pH, alkalinity, and hardness control or chemical sanitizers to maintain clear water.
- Maintenance frequency: Some systems offer long intervals between cartridge changes or dosing, reducing hands-on maintenance.
- Spa type compatibility: Ensure products work with your tub’s material (acrylic, inflatable, wood) and heater or pump configuration.
- Foam and clarity management: If foaming or cloudy water is a concern, prioritize defoaming agents and clarifiers that suit your water chemistry.
- Deliberate additive blends: Multi-function kits simplify purchases but check if all components (test strips, pH adjusters, hardness increasers) align with your needs.
- Safety and storage: Read safety guidance for handling concentrated chemicals and store them away from children and pets.
- Cost and replacement cadence: Assess the long-term cost by considering cartridge life, dosage frequency, and storage requirements for each product.
- Compatibility with sanitizers: If you already use mineral systems or ozone, confirm compatibility to avoid additive conflicts.
