Swimming pool ionizers
Swimming pool ionizers, the friendly healthy way to clean your pool.
Another, less common, but still effective type of pool cleaner is an Ionizer. The main advantages to these is that they reduce the amount of chemicals needed to keep your pool clean and healthy. They are also more environmentally sound then other methods. The basic principle is that Ions are released into the pool to kill harmful bacteria, algae, and other such.
The three major variations are Solar, Electric, and Ozone Generators. Solar is just that: powered by the sun. They release ions into the water as they float, cordless, across the surface. Electric Ionizers must be plugged into an electrical outlet, or battery powered. Ozone Generating ionizers create Ozone (O3) and release it into the water. These have become very popular recently.
