How to Sanitize Your Swimming Pool

Every swimming poolregardless of size, system, or frequency of usewill need to be sanitized periodically. Sanitizing your pool eliminates harmful microorganisms such as bacteria and algae, making it safer for swimmers. However, there is no single best method for sanitizing a pool. Which method is best for you will depend on the type of system you have, how often the pool is used, and how much you want to invest in maintenance. Here are a few of the most popular pool sanitation methods and their benefits.


One of the most common ways to sanitize a chlorine pool is by ‘shocking’ it. Shocking your pool, also known as superchlorination, consists of adding a larger-than-normal amount of chlorine to your pool water. This large amount of chloration will destroy any contaminants and sanitize the water, even destroying algae and bacteria. Shocking should be done as the pool filter is operating, but try to do it at nighttime to avoid the loss of chlorine due to UV rays. Chlorine shocking is popular because it’s a cost-effective way to achieve long-lasting sanitation. However, chlorine can be irritating to the eyes and skin, which is why some pool owners prefer other methods.

Salt Sanitation

Salt chlorine sanitation is a method that has become increasingly popular with homeowners in recent years. When you have a saltwater pool, salt chlorine generators convert salt to chlorine utilizing a process called electrolysis. This process is regenerative, as the salt turns into a sanitizing solution and that solution, called hypochlorous acid, turns back into salt. This process makes saltwater pools a low-maintenance choice that provide constant sanitation. The downside to saltwater, however, is that it is corrosive. Salt water can degrade your pool coping and may lead you to require pool tile repair. When choosing salt sanitation, always keep your pool decking materials and possible pool replastering in mind.

UV Sanitizing Light

UV sanitation is a powerful method that can kill or deactivate microorganisms using short-wavelength UV light. UV light is a preferred method for many because it can destroy bacteria and algae as well as chlorine-resistant pathogens such as E. Coli. UV light is different to other methods because it doesn’t involve the use of chemicals in the process. Instead, UV light physically disrupts the microorganism’s DNA, rendering it harmless. The UV method has no harmful side effects, so you don’t need to worry about pool replastering or pool tile repair like with salt sanitation and other harsh chemical methods. However, it is a more expensive option, which limits its availability to some homeowners.
