Master Clear Non-Chlorine Oxidizer: 5 lbs of Active Oxygen Shock for Hot Tubs
Master Clear Oxidizer is a non-chlorine shock treatment that uses active oxygen to eliminate organic waste and restore water clarity in your hot tub. This 5 lb container of fast-dissolving granules works alongside your regular sanitizer to break down contaminants like body oils, lotions, and sweat without adding chlorine to your water.
Key Features & Specifications
- Non-chlorine formula: Uses active oxygen instead of chlorine for oxidation
- Weight: 5 lbs of oxidizing granules
- Fast-dissolving: Granules dissolve quickly for immediate treatment
- Sanitizer booster: Enhances the effectiveness of your existing chlorine or bromine sanitizer
- Targets non-bacterial waste: Eliminates organic contaminants that cause cloudy water and odors
How Non-Chlorine Oxidizers Work
While your regular sanitizer (chlorine or bromine) kills bacteria, it can become overwhelmed by non-bacterial organic waste from bathers. A non-chlorine oxidizer like Master Clear breaks down these contaminants into gases that dissipate naturally, freeing your sanitizer to focus on bacteria. This results in clearer water, less chemical odor, and more effective sanitization.
When to Use
Use Master Clear Oxidizer as a weekly shock treatment or after heavy spa use. Because it’s chlorine-free, you can typically re-enter the spa sooner than with a chlorine shock — always test water before soaking. Follow dosage instructions on the product label for your spa’s water volume.
