Ideal for small to medium-sized the ponds which are directly fed from a pump in the pond, since the filter is a sealed unit, the water leaving the filter is still under pressure, allowing more flexibility in positioning of the unit eg even below the water level, they can be almost completely buried or covered with decorative rock for almost invisible integration in the water garden.
Note. The filter system needs to circulate the total pond water volume once every 2 hours with fish stock.
