Standard pool chlorines — calcium hypochlorite (cal-hypo) and trichlor — are designed for outdoor pool volumes and chemistry, and will damage spa equipment over time. Cal-hypo raises calcium hardness with every dose, eventually scaling heaters and salt cells. Trichlor is acidic, driving pH down aggressively and corroding spa interiors. Dichlor is pH-neutral, dissolves quickly in spa-temperature water, and is the form chlorine should take when added to a residential hot tub.\u003c\/p\u003e\n\u003cp\u003eTwo situations where the 2 lb size is the better choice than the 3.5 lb:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew chlorine-program owners\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ewho want to try the FreshWater chemistry program before committing to a year's supply\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSalt System, ACE, or Ag+ Silver Ion owners\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ewho only use chlorine for periodic shock — not enough volume to justify a 3.5 lb container before it ages\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmaller spas, plunge pools, and inflatable hot tubs\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ewith lower total water volumes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacation homes and seasonal-use spas\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ewhere the tub isn't running year-round\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor households running a chlorine program full-time on a typical 400-gallon spa, the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e3.5 lb container\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eis the better per-pound value.\u003c\/p\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cstrong\u003ePro Tip:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eTarget sanitizer residual for a chlorine spa is\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e2–3 ppm of free available chlorine\u003c\/strong\u003e.
