Jets are very often overlooked by beginners when building a pond. Anyone who has ever had properly installed jets in their pond would never consider building a pond without them. Jets have several wonderful benefits. They provide exercise for the fish because they love to swim in the current. By installing the proper type of jets, in the right location and depth in a pond, they can be used to direct leaves toward the skimmer making the skimmer much more effective. In addition, as the water from the jets breaks the surface of the pond it picks up considerable amounts of oxygen thus increasing the overall oxygen level of the pond.
