500M Lake Diffuser SystemThe 500M Lake Diffuser System is an advanced sub surface aeration kit designed to aerate large ponds and lakes up to 500m with a depth of up to 3 meters.

The air is then distributed via 30m lengths of 1 2" internal diameter weighted airline to 3 self sinking diffuser assemblies. Key Features:
