Cloudy water, weak readings, and skin irritation are usually the first signs. Some owners try to compensate by cranking the system's output level higher — but that only accelerates the wear on the depleted cell and can damage the controller. Replacing on schedule is cheaper than rebuilding the system.\u003c\/p\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cstrong\u003e⚠️ Counterfeit Warning:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eWatkins Wellness and Hot Spring have publicly warned consumers about counterfeit FreshWater salt cartridges sold on Amazon and other online marketplaces.
