what does non chlorine shock do

Maintaining a sparkling clean and healthy swimming pool involves more than just chlorine. Non-chlorine shock, also known as a non-chlorinated oxidizing shock, plays a crucial role in keeping your pool water pristine. This article will explain exactly what non-chlorine shock does, how it works, and when you should use it.

Understanding the Role of Oxidizers in Pool Care

Before diving into non-chlorine shock, let's understand the importance of oxidizers in pool maintenance. Chlorine, while a powerful sanitizer, primarily tackles bacteria and algae. However, it's less effective at breaking down organic contaminants like sunscreen, sweat, leaves, and other debris that can cloud your water and create an unpleasant smell. This is where oxidizers come in.

Oxidizers work by breaking down these organic contaminants, preventing them from combining with chlorine to form chloramines – the compounds responsible for that harsh chlorine smell and irritated eyes. They essentially "clean up" the pool, leaving chlorine free to focus on its primary sanitizing tasks.

What is Non-Chlorine Shock?

Non-chlorine shock uses different chemicals than chlorine to oxidize the pool. The most common active ingredient is potassium monopersulfate (MPS). This powerful oxidizer effectively eliminates organic contaminants, leaving your pool water clearer and smelling fresher.

Key Benefits of Using Non-Chlorine Shock:

  • Effective Oxidation: It efficiently removes organic contaminants, improving water clarity and reducing unpleasant odors.
  • Gentle on Pool Surfaces: Unlike some chlorine-based shocks, MPS is generally gentler on pool surfaces, minimizing the risk of damage or discoloration.
  • Compatible with Chlorine: It can be safely used in conjunction with chlorine, enhancing its effectiveness.
  • Faster Oxidation: It often works faster than traditional chlorine shock, improving water quality more quickly.
  • Environmentally Friendly Option: Some consider it a more environmentally friendly alternative to chlorine shock, though this is a complex issue with varying opinions.

How Does Non-Chlorine Shock Work?

Non-chlorine shock, containing MPS, releases oxygen radicals that break down organic contaminants. These radicals oxidize the contaminants, converting them into harmless substances that can easily be filtered out of the pool water. This process helps prevent the formation of chloramines and keeps your pool water clean and clear.

When Should You Use Non-Chlorine Shock?

You should use non-chlorine shock regularly as part of your pool maintenance routine. A good schedule might include:

  • After a heavy swim: Following a busy swimming period, especially with many swimmers, using non-chlorine shock helps eliminate the excess organic matter.
  • After a storm: Rain can introduce leaves, dirt, and other contaminants to your pool. Shock treatment helps clean this up.
  • Before closing your pool for the winter: This ensures your pool water is clean and prevents organic material from causing problems over the winter months.
  • Whenever the water appears cloudy or smells bad: If your pool water looks or smells off, non-chlorine shock can be a quick fix.

How to Use Non-Chlorine Shock: A Step-by-Step Guide

  1. Test your water: Before adding any chemicals, test your pool water to ensure proper balance.
  2. Calculate the amount needed: Follow the instructions on the packaging to determine the appropriate amount based on your pool's size.
  3. Add the shock: Dissolve the non-chlorine shock in a bucket of water before adding it to your pool. Pour it slowly into the deep end while the pump is running.
  4. Run the filter: Keep your pool pump running for at least 12-24 hours after adding the shock. This allows the filter to remove the oxidized contaminants.
  5. Retest your water: After 24 hours, retest the water to ensure it's balanced.

Non-Chlorine Shock vs. Chlorine Shock: Key Differences

While both shock treatments aim to clean your pool, there are key differences:

Feature Non-Chlorine Shock (MPS) Chlorine Shock
Active Ingredient Potassium Monopersulfate (MPS) Calcium Hypochlorite, Sodium Dichloro-s-Triazinetrione, etc.
Primary Action Oxidation of organic contaminants Sanitization and oxidation
Impact on Chlorine Enhances chlorine effectiveness Can deplete free chlorine levels
Pool Surface Generally gentler Can be harsh on some pool surfaces
Smell Usually less pungent Strong chlorine smell

Conclusion

Non-chlorine shock is a valuable tool for maintaining a clean, clear, and healthy swimming pool. Its ability to effectively oxidize organic contaminants, without the harshness of some chlorine-based shocks, makes it a popular choice among pool owners. By understanding how it works and when to use it, you can ensure your pool remains a refreshing oasis all season long. Remember to always follow the product instructions and test your pool water regularly.
