This powerful filtration system keeps your pond clean and sparkling while providing a nice waterfall display. Water runs through the 3 large media chambers into the separable bulkheads to create a wide 19-inch spillway. You may adapt the bulkheads into separate waterfalls or combine them into one to get the ideal display in your pond. The water oxygenating spray bar, venturi valve, and water drain ensure pure and clean water. Laguna Coarse Filter, Laguna Biospheres, and pre-filtration brushes are included. A 2000 - 3000 gph pump is recommended but not included.
