Setterguy, like you, I hade some old garden hose around the place. And I try to recycle as much as possible, so I will pass on what I did with the water hose. I had some 4" green pvc pipe and I added some 1" pvc at both ends of the pipe, where each end had a big X pattern, keeping the 4" pipe in a horizontal position, just a couple feet off bottom of the pond. I then added short cut off pieces of the garden hose,( 2 to 3' ) cut offs and placed them into holes drilled into and all around the horizontal 4" pipe. it worked out pretty good, (I thought) and will provide some good horizontal structure. I sank it in about 7' of water, nest to the deeper water. Sorry no pictures.

Hope this gives u an idea of what to do with extra stuff laying around your place. I also pick up things along the road side, like discarded tires, etc.
