Pond Skimmers or Pond Surface Skimmers are a very beneficial addition to any pond filtration system and greatly reduce maintenance. While they come in many sizes and variations they all serve the same fundamental purpose, that is remove floating debris from the water service before they sink and clog other components of the filtration system. A sort of mechanical prefilter that removes leaves, pollen, whirly birds and anything else that falls from the sky. They are easy to install and hide but should be placed on the opposite side or end of a waterfall, or other water outlet, to provide good water circulation. A cluttered pond surface is unhealthy and unsitely.
Pond skimmers collect debris and dirt from the surface of the water, keeping your pond clean. Most pond skimmers also house the pond pump, and contain filter media to clean the water.
