While both pools and spas require chemical additives to sanitize and condition the water, there is a big difference between cold water and hot water chemistry. In many cases the chemicals used are the same, but in some instances they are radically different. Never use pool chemicals in a spa without first making sure they are compatible with hot water!

Like pool water, when a spa is filled with your garden hose it is generally chlorinated and fluoridated. But left untreated, water is a perfect host for all kinds of living organisms and mold. Spa water, because it is kept at a high temperature, is particularly susceptible to organic growth. The most important chemical your spa needs is some form of sanitizer to kill bacteria. There are several different types of sanitizers available. Choose from our wide selection of products to find the solution that is right for you.
