As Snrub requested, here is a video to begin with for my solar aerator setup: https://www.youtube.com/watch?v=6oQ_Xa9p2M4 More coming soon showing all the equipment. The rope in the video is what we used to lower the diffuser. I'll pull the rope from it when I'm sure I don't want to move it again anytime soon. It's poly rope, is it okay to just leave in place? Affect anything at all?
