Hot Tub Serum Dichlor | Spa Chlorine Granules
Hot Tub Serum Dichlor is a fast-dissolving, stabilized chlorine sanitizer for hot tubs and spas. Its granular sodium dichlor formula dissolves quickly and completely, providing a steady source of available chlorine that controls algae, kills bacteria, and destroys organic contaminants — the core sanitizing your spa needs to stay safe and clear.
Sanitizer is the single most important part of spa water care. A hot tub is warm, agitated, and used at close quarters — ideal conditions for bacteria. Chlorine keeps that water safe to soak in, neutralizing bacteria continuously between uses. Let it drop and the water can turn cloudy, develop an odor, and stop being sanitary; keep it in range and the water stays clear and worry-free.
Because these granules are stabilized against UV, the chlorine resists burning off in sunlight — slowing the decay rate and extending the life of your treated water in an outdoor spa. And they're designed to work seamlessly with Hot Tub Serum Total Maintenance, so your chlorine and your weekly biofilm care work as one regimen.
