Ozone gas is excellent for cleaning my pool water (http://www.homemadetools.net/forum/c...5142#post81245 ). I have used the system for more than 20 years and have made several modifications. When the tiny ozone bubbles are used in combination with a pool chlorination system there is nothing that can live in the pool water for very long. The ozone is very active and bounds with organic impurities before reaching the water surface. I also have a way to remove the phosphates from the pool water (phosphate comes in after a good rain storm) and it is the phosphate that help the algae grow. When there is no or extremely low amount of phosphate there is zero algae. Using shock to kill the algae only helps to dissolve the dead algae and return the phosphate to the pool water for the next crop of algae.
