Sanitizing Your Pool Water

Expert Advice

The second step in maintaining perfect pool water is to properly sanitize your pool water. Sanitizers are used to kill bacteria and inhibit the growth of viruses, algae and other organic contaminants that enter your pool water by way of wind, rain, dust and swimmers. The most common pool water sanitizer is chlorine.

Chlorine is the most cost effective way of sanitizing your pool and has been a product of choice for over 100 years. Nothing purifies and disinfects better than chlorine. Chlorine must be in your pool at all times and maintained at the ideal “free available chlorine” range. Free available chlorine is the amount of chlorine left to kill new bacteria entering the pool. This is what sanitizes your pool continuously.

We offer two types of chlorine-based sanitizers - stabilized and unstabilized. Our stabilized chlorine sanitizer contains cyanuric acid, which protects the water from chlorine loss caused by the sun's ultraviolet rays.

Chlorine may be added daily, weekly or monthly depending on the type used. Stabilized chlorines are conveniently dispensed by placing them in a skimmer basket, chlorinator or floating dispenser. While unstabilized chlorine should be added directly to the pool water.

* The amount of chlorine you will need to add to your pool water is affected by many factors. These include high water temperatures, heavy pool usage, and heavy rainfall and pH levels of the pool water. It is important to measure your free available chlorine level often and adjust your dispenser as needed to increase or decrease the flow.

** Read labels and follow instructions carefully before adding any chlorine to your chlorinator or floating dispensers.
