ML, Sue and others,

This question is tangent to the original post so I apologize but I'm curious to know if anyone maps out or marks the location of underground aeration lines for future reference/landwoners.

Currently, I have one aeration line running off the corner of my outbuilding to my BG pond. This line is only 10' long so its path is simple to see. I plan to run an aeration line to my other pond and thought about burying a piece of metal wire alongside the tubing for future reference. The metal wire would be something that could be picked up with a metal detector.
