FROG® SooTHe™ Spa Water Conditioner – Softer, Clearer Hot Tub Water

FROG® SooTHe™ increases calcium hardness in spa water, helping prevent corrosion, surface etching, and premature equipment wear caused by water that is too soft. Restores water to the recommended hardness range, improving overall stability and supporting easier long-term maintenance. Helps reduce foaming and improves water clarity by preventing mineral imbalance that affects circulation and filtration. Features the FROG® TruDose™ Cap, which seals tightly and includes built-in measurement marks for precise, mess-free dosing. Ideal for new spa start-ups, ongoing maintenance, or anytime hardness levels drop due to dilution, refills, or heavy use. Compatible with all sanitizing systems, including chlorine, bromine, and FROG® SmartChlor® cartridges.
