Skimmer features innovative design allows you to choose between a vertical filter mat or filter brushes. Removable center divider, creating two chambers in the skimmer box - one for filtering and one for the pump. Two chamber design eliminates cutting filter pads to fit around the pump and plumbing. Pumps can be inspected or removed without removing mesh net or filter pad. Skimmers have a flange above the opening where water enters from the pond into the skimmer, allowing you to not only stack rocks along side but also above the skimmer opening. Provides an ideal place to hide the pump from view. Internal filters prevent plugging and are easy to clean. Skimmers have a one piece debris net, design keeps mesh in place and is easier to clean.
