You may have heard the term “shock” pool bandied about among pool owners. This is actually a very important aspect of pool maintenance. Shocking a swimming pool—also called super chlorination—is actually a very important step in pool management, so it’s important that you understand the when, why, and how of shocking a pool. Most pool owners don’t even think about shocking their pools until they step out and see either algae, cloudy water, or both. However, by shocking the pool, these issues can be avoided.
Why Do You Need to Shock Your Pool?
When people swim in the pool, organics and contaminants are introduced into the water through things like saliva, sweat, skin cells, body lotions, urine, and many other such things. Natural contaminants such as leaves and dirt can also contaminate the water. These substances are a food source for algae and bacteria. Using pool sanitizers (such as chlorine) can kill the bacteria/algae and breakdown contaminants.
Types of Pool Shock
Essentially, there are two different types of pool shock: chlorine and non-chlorine. When using chlorine, the levels of chlorine in the pool raised very high to destroy contaminants. When using this type of pool shock, you have to wait for the chlorine levels to lower to normal levels before you can use the pool. This can take time, and testing is required.
With non-chlorine treatments, potassium monopersulfate is used rather than chlorine. While it is effective at oxidizing contaminants, it will not kill bacteria. The main benefit of this type of pool shock is that you don’t have as long of a wait to use the pool afterwards.
Maintaining your pool’s proper chemical balance can reduce the need to shock your pool. And of course, this is done through regular maintenance and monitoring of chemical levels. However, you may find that even the best monitoring and care can cause issues with your pool. This can happen through heavy use, after a rain or windstorm, or even after a water change.
