You know I think I've seen these before. I had no idea what they were. I was Kayak fishing a small farm pond and I saw several wood squares covered in foliage out in the lake. I thought it was something for the fish, but after seeing your video I think it was duck islands. Thanks for the video. Pretty neat. Great job by the way.
Those bottles are not “extra flotation” … if anything, there’s ever so slightly less air inside the pipes, because of bottle plastic and lids. It does prevent a compromised seal completely filling the pipes, though. But it’s not extra air.
Very good👍👍

Thank you for sharing. Can you please tell me how they did after a winter freeze? Did they come back ok?

Yeah, they are a back-up. They are only helpful in the event of water flooding into the pipes
