I've got it!!
I'm going to design a return waterflow, that won't use a pump on the aquarium water and it will be fairly efficient. This has been a dream of mine and I figured out how to make it work. This will be an Advanced DIY Project as it will require a somewhat complicated engineered structure that will take up some space, and there are a few difficulties that I can think of, and probably twice as many that I haven't, the most important of which is how to make it all failsafe, but I find myself solving the problems I can think of quickly and looking forward to building it. Fortunately I have a sizable place to hide such a structure.
When I have plans and pictures I will post them in a quality linkable thread, and challenge people to make one simpler, because mines definately gonna be complicated, although I'm going to be applying the KISS rule as much as possible so we'll see. I was so excited when I thought of it that I had to post. I will use this thread for any technical questions and updates I may have about this project.
