A: No. Many hot tubs and spas come "ozone ready," meaning the hot tub is equipped for easy installation of UV or CD ozone systems. (For a complete explanation of ozone systems and their benefits, see the "Hot Tub Features" section of our web site).
Most often, ozone systems are optional, and are added to the price of the hot tub. However, it is important to remember that ozone systems help to maintain clean, clear water, and reduce the amount of required chemicals. Over the long run, an investment in an ozone system is a good one.
