The combination of a pond skimmer and pond filter is one of the best ways to ensure a clear and clean pond. Filter falls use coarse and fine material to remove debris from the pond water which can cause cloudy water or green water. The skimmer system uses screens and gates to trap floating pond debris and scum. The use of a filter falls with a pond skimmer is one of the most efficient ways to keep a pond clear.
UV filters can also be combined with filter falls and skimmers to further improve the pond cleaning process.
