Also why does the planted part of river need to be narrower and longer again? I was thinking of having the air lift �exhaust� into an area almost like a wetland: wide. shallow, and maybe 100 feet long, filled with plants. What do you think of this? What is the right depth so that filtering plants can grow, and yet it doesn�t �fill in� too fast?
Also any particular reason why I should pull from as deep as possible? I figure if I get the intake part way down water should still get sucked in from all around, including the deeper areas. What do you think?
