Pond pumps 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 is becoming dirty and fish will 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.
