Laguna Filter Spillway is for ponds up to 4500 litres/1000 U.S. gallons. The Filter Spillway can be installed in or above ground and is easy to use and maintain. A faceplate is included to allow easy liner attachment. The unit has a 38 mm (1-1/2 in) threaded bulkhead for making a hose connection to a circulating pump, such as a Laguna Max-Flo pump (sold separately).
As water flows through the Filter Spillway, it passes through filter foam and biomedia, both providing mechanical and biological filtration. Completely filtered water then exits the unit over a 37 cm (14-1/2 in) wide spillway in stunning waterfall fashion.
The Filter Spillway is made of solid, professional grade fiberglass that will provide lasting durability. The Filter Spillway is covered by a 2-year warranty.,
