The original question was about the intake and it being hidden. So long as it's not blocked I don't see a problem. For tank appearance, I give a two tumbs up for the lava rock to right, artificial in the middle, wood to left. I really like that, and think it looks "natural". I don't care about accuracy, I just like something that visually flows and looks good. For me, and maybe me a lone that really works particularly with your planting plans.
Care to fill us in on what plants you plan on using and stocking?
