The Aquascape Pond Filter Urn provides efficient mechanical and biological filtration for smaller ponds up to 500 gallons, including preformed ponds or container water gardens. The decorative filter housing allows the filter to be easily integrated into almost any setting, adding the sight and sound of trickling water to ponds without waterfalls or streams. It can also be added to existing ponds to provide additional filtration. The filter is simple to use, and its removable filter lid allows easy access for cleaning and maintenance. The Aquascape Pond Filter Urn contains a filter mat that provides mechanical filtration, while the ceramic filtration rings provide substantial surface area for beneficial bacteria to colonize, optimizing biological filtration. Aquascape Pond Filter Urn can easily be incorporated into existing ponds with a 1/2-inch water hose connection and is ideal for use with pumps up to 400 gallons per hour. Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
