Ok so I wont be able to do this project for another year but I couldnt wait to share. I dont know if anyone has done this but I think it can be done. The island in the middle will be for a turtle. Sorry about the under par diagram. I did it on photoshop. the finished product will be lined with brick and have a rock formation behind the top tank with a waterfall that wraps around the upper tank. I know its not in the diagram but I'm not that good at photoshop.
anyways let me know what you think of the general idea. I'll be thinking up new things and changing the design several times before making the actual finished product.
