HTH Spa Non-Chlorine Shock Oxidizer for Hot Tubs — 2.25 lb Powder, Clears Cloudy Water & Reduces Odors

HTH Spa Non-Chlorine Shock Oxidizer is a powdered oxidizer for spas and hot tubs that clears cloudy water, reduces odors, and refreshes water without adding chlorine.

Designed for routine spa maintenance, this 2.25 lb container of HTH Spa 86135 supplies a non-chlorine shock treatment that works with both bromine and chlorine systems. It oxidizes organic contaminants such as body oils and lotions that cause cloudiness and unpleasant smells, helping restore clearer, fresher water between regular sanitizer doses. Because it is non-chlorine, it avoids the bleaching and strong chlorine scent associated with some shocks while still improving water clarity and overall comfort.

How does HTH non-chlorine shock improve cloudy spa water?

This oxidizer breaks down organic waste and combined sanitizer byproducts that make water look dull or hazy. It does not replace your sanitizer; instead it complements sanitizers by oxidizing contaminants so filters and sanitizers work more effectively.

• Oxidizes body oils, lotions, and organic debris that cause cloudiness.
• Helps filters trap finer particles after oxidation.
• Compatible with bromine and chlorine systems; used between regular sanitizing treatments.

Use HTH Spa Non-Chlorine Shock regularly as a maintenance step or whenever water becomes cloudy or develops a mild odor. Follow dosing instructions on the label for your spa size and re-enter time recommendations; typically the product dissolves quickly and requires little waiting for normal use.

• Treat weekly as part of routine upkeep or after heavy spa use.
• Add with the pump running to distribute the oxidizer evenly.
• Observe manufacturer directions for dosage based on gallons and re-entry timing.
