1000M Lake Diffuser SystemThe 1000M Lake Diffuser System is a robust sub surface aeration kit designed to enhance the oxygenation and circulation of large ponds and lakes up to 1000m (approximately 1 4 acre) with a depth of up to 3 meters. This system delivers superior performance by pumping air from a shore mounted AP12000 air pump through a valved brass manifold assembly. The air is then distributed via 30m lengths of 1 2" internal diameter weighted airline to 3 self sinking
