I still have a couple of 8" pipes to use up. That was the 12" section. I ended up using over 400' of 1/2" tube on the first one so I think I'll back it down on the next one.

There is a shallow water "shelf" where the boat parks and the baby bluegill and some minnows/tadpoles, dragonfly hang out up under the boat. I'm thinking the one 8" tube will get shorter branches and less qty and I'll stash it under the dock so that the one end is up in the shallow.

I parked the 12" pipe right by my Christmas trees.
