Yes. These are closed systems. Otherwise, tremendous water volumes would be wasted. Plus, a lot of time would be consumed filling them. Contained water, especially fresh water must be treated to control bacteria and algae. This is particularly true in locations like these that receive lots and lots of sun light. In addition to physical filtration, there is chemical treatment. The most effective filtration media is diatomaceous earth. There are several ways to chemically treat the water: 1) chlorine (like many swimming pools), 2) ozone and/or ultra-violet light (like water treatment plant), and 3) electrolytic salt (like some swimming pools in which operator wants less chlorine than traditional chlorine pool. Even though called "salt water" pool, it isn't really. The "salt" refers to a different chlorine generating process. Instead of adding chlorine to the pool, you add salt that is converted to chlorine when it passes through and electrolytic converter. The water is slightly salty, but mostly fresh and the water feels softer). I know these things from designing and/or maintaining water treatment plants and swimming pools. However, I have not found out what the Surf Ranch is using. If someone in our forum knows, then please tell me.
