So I am a former long-time reef aquarium enthusiast although I have not had a reef tank in ten years. Now that I am retired, I am dreaming of placing a tank in my current home. I want to place a cylindrical tank in the corner of a spiral staircase (not in the center of the spiral staircase, but on the periphery) with the base at about 1/2 way up the stairs. So one side of the tank would be visible going up the stairs. The opposite side of the tank would penetrate the wall between the staircase and the living room. Thus the tank could be seen from the corner of the Living room. There are multiple tall rectangular windows to the exterior of the home that partly encircle the spiral staircase seen in the photo, and the goal is that the aquarium could also be seen through these windows from the exterior of the house as well. I know that 10 feet would be very difficult or impossible to get light down to the bottom to keep a live reef alive, so that obviously is an issue. One thought that crossed my mind is to have a perhaps 6" wide band of a lighting fixture conforming to the curve of the cylinder which could potentially be mounted on the staircase side and/or the living side of the cylinder that would be mounted on rails hat would slowly move up and down from the base to perhaps 7-8 ft up the tank constantly during the day in order to give light to deeper parts of a live reef. Could have lighting at the top of the tank for the upper 3' of the tank. Anyway just a thought. So i just spoke to a local custom reef tank builder and discussed my desires and he will be coming out next week to check out the house. Yes I know this would be a very expensive and difficult build. Any thoughts?? Yes I know cleaning and access to the tank would be highly limited. Yes I realize that a Fish only tank would be much more doable. Attached are photos of the spiral staircase , and the view from inside the living room and the corner where the cylinder would come out from the wall.
