Maintaining a hot tub can be a relaxing and enjoyable experience, but it also requires careful attention to water quality. One of the essential tools in your hot tub maintenance kit is Non-Chlorine Shock for Hot Tubs. This guide will explore what non-chlorine shock is, its benefits, and how to use it effectively.
What is Non-Chlorine Shock?
Non-chlorine shock, also known as MPS (monopersulfate), is a powerful oxidizer used to keep hot tub water clean and clear without the use of chlorine. It works by breaking down organic contaminants such as body oils, lotions, deodorant, dead skin cells, sweat, detergents, and leaves, helping to prevent foaming and reduce strain on your hot tub filters.

Benefits of Non-Chlorine Shock
Improved Water Clarity: Non-chlorine shock helps to clarify cloudy water by oxidizing non-living organic and inorganic particles. This results in crystal-clear water, enhancing your hot tub experience.
Enhanced Sanitizer Efficiency: Using non-chlorine shock alongside sanitizers like bromine or chlorine can boost their effectiveness. This means you need less of these agents to maintain a clean and healthy hot tub environment.
Reduced Chemical Odours: Non-chlorine shock helps to break down chloramines, which are responsible for the strong chlorine odour often mistaken for too much chlorine. This improves your bathing experience by reducing eye irritation and unpleasant smells.
Regenerates Spent Bromine: Unlike chlorine, bromine can be regenerated. Non-chlorine shock oxidizes bromide ions (spent bromine) to form new bromine, boosting the bromine level in your hot tub.
Gentle on Skin and Equipment: Non-chlorine shock is less harsh on your skin and hot tub equipment compared to chlorine-based shocks. This makes it a suitable option for regular maintenance without the risk of bleaching or damaging surfaces.
How to Use:
Preparation: Ensure your hot tub is on, but turn off the jets while keeping the circulation pump running. Wear safety equipment like gloves to protect your skin.
Dosage: Check the label of your non-chlorine shock product for the correct dose. A common recommendation is 2 ounces per 200 gallons of hot tub water.
Application: Slowly add the non-chlorine shock into the hot tub, near a water inlet to help spread it evenly. Allow the shock to circulate for the recommended time before using the hot tub again.
Testing: After the treatment, test the water using test strips or a digital hot tub tester to ensure it is safe for use. Regular testing helps maintain optimal water quality.
When to Use:
After Each Use: Adding non-chlorine shock after each use helps maintain water clarity and reduces the build-up of contaminants.
Weekly Maintenance: Incorporate non-chlorine shock into your weekly maintenance routine to keep your hot tub water clean and clear.
Special Circumstances: Use non-chlorine shock in situations like severe foaming or cloudy water to quickly restore water quality.
Conclusion
Non-chlorine shock is an essential tool for maintaining a clean and healthy hot tub environment. Its ability to oxidize contaminants, enhance sanitizer efficiency, and reduce chemical odours makes it a popular choice among hot tub owners. By following the guidelines outlined in this guide, you can ensure that your hot tub remains a relaxing and enjoyable oasis.
