Hot Tub Things® Chlorinating Granules – Premium Fast-Dissolving Spa Sanitizer
Hot Tub Things® Chlorinating Granules are a concentrated dichlor (sodium dichloro-s-triazinetrione) sanitizer specifically formulated for hot tubs and spas. Unlike traditional chlorine tablets designed for pools, our granules dissolve quickly in warm water, providing immediate sanitization without leaving residue or affecting your spa's pH balance significantly.
This fast-acting formula eliminates bacteria, viruses, and organic contaminants, ensuring your hot tub water remains crystal clear and safe. Whether you're maintaining daily chlorine levels or shocking your spa after heavy use, our chlorinating granules deliver consistent, professional results.
