Ponds and waterfalls provide a pleasant environment and create habitats for birds, small mammals, and various reptiles and amphibians. To keep the water that is contained in a self sufficient pond from becoming foul and stagnant it is necessary to include pond skimmers. Skimming relates to filtering or purifying the water in an aquatic life support system such as a pond.
Typically water in a pond is continuously circulated through some combination of pond skimmers and filters, thus reducing the overall amount of debris or matter on the surface area of the water. Water movement is important to oxygenate the water for the pond to support aquatic life. Fish, water plants, amphibians, etc. can thrive in a well aerated pond.
The surface or pond skimmer draws surface water from the pond and into its core where leaves and other floating debris are removed via filtration. The skimmer utilizes a submersible pump to draw the water into its unit. The actual filter function of the skimmer is performed by a net, basket or other strainer device. These filter apparatuses all have some type of entrapment meshing / web which can capture the larger particles from the water. The particles entrapped within the strainer are later removed from the filtering element manually which detaches from the skimmer. Once removed, the debris can easily be taken to a waste receptacle. Most ponds and waterfalls can include pond skimmers as part of its overall system to enhance its operational function.
