another problem will be power to your tank for all the various equipment. i'm assuming this is in the basement, because of the concrete below the hardwood floor?
because this is hardwood on top of concrete, there probably isn't a lot of room between the two. otherwise you're left with running extension cords.
one idea is to use corner columns running from floor to ceiling. this way you can use the columns to hide the plumbing and run the electrical power along the ceiling, which would be easier to hide.
sorry... just spit-balling
