I made a model out of yard sticks. Its alot more of a cube that I thought. How ever, I will still need a creative solution for air. I don't like bubble columns and will sleep just inches from it so that rules out the conventional air line to the bottom with a stone. The filter, unless I hear ( hint ) of something good as or better than an Aqua Clear ( AC ) for the same price, filter won't help me. I think, anyway. I could run a pipe from the bottom of the tank all the way up the back ( on the out side ) and have it pour back into the top, the top of the pipe being open. An air column in it during the day. It would also help circulation in the rock work.
