30m DeepWater Underground Airline

30m roll of unweighted underground air hose is designed for use with DeepWater Aeration Systems, allowing for discreet, below-ground installation from the compressor cabinet to the pond edge. With a 12mm internal diameter and 16mm external diameter, it provides a practical way to route airline neatly out of sight before connecting to the weighted airline system. It is intended to be used in combination with up to 100m of DeepWater weighted airline per diffuser, helping to create a tidy and efficient aeration setup.
