A pond pump provides a healthy and clear pond. Thus pond fish and water plants find the pond more to their liking and you will be confronted with fewer diseased fish and less pond maintenance. Often too many fish are swimming in the pond. As a result of this the water becomes dirty and the fish get insufficient oxygen. If you take care that the water is filtered and oxygen rich, this need not be a problem. A pond pump ensures circulation of oxygen rich water and in this way you will keep your pond clean and healthy.

An air pump can be installed near a pond. The pump will send air into your pond though a hose, providing additional oxygen. An air pump also makes use of aeration stones. Air stones cause the air to be diffused into small bubbles creating a bigger contact area with the water thus improving the oxygen levels in the pond.
