Product: Filters - Pressurized External
External bio-filtration which uses a pressurized system to enhance filtration. These filters are usually buried apart from the pond and is powered using a pump system, running from your skimmer and sometimes be made to power your waterfall. There is the option with this type of filter to use an in pond pump which is able to pump some solids but will not clog.
Pressurized external filters simplify maintenance and upkeep by being positioned outside of your pond. This keeps the filters free of the debris found in pond water, making them a great alternative for those who prefer not to use submersible pumps. The filters can be buried in the ground, so they will not detract from your landscaping and offer efficiency similar to that of standard submersible pumps.
