In its simplest terms a pond skimmer filter is a mechanical pond filtration system that removes leaves, grass cuttings and other vegetation that can be found, floating on the surface of your fish pond. They are particularly useful during autumn (fall) when trees start to shed their leaves; usually into your pond, unfortunately!
A pond surface skimmer doesn’t simply remove the pond surface debris so as to maintain the look and feel of your fish pond. By removing excess pond surface debris it also helps to ensure that the debris can’t fall to the pond floor and form sludge; thereby removing the opportunity for unwanted bacteria colonies to form. The build up of these heterotrophic bacteria encourages fish disease and the release of toxic gases, such as hydrogen sulphide.
