I built a curved glass staircase and two of the curved balcony panels didn't get used and so I've been trying to think of a design for a tank that could incorporate them. The glass is 1/2" heat strengthened laminated safety glass so it can't be cut or drilled, but it will act as the front piece so there's no drilling needed anyway. It does however limit the size of the tank. The glass is 45-3/4" tall with a 29-9/16" radius with a width of 35-5/8". I considered doing a fish only tank that was just very tall, but thought of splitting it so that there was a display tank up top and then a displayed refugium and sump in the bottom of it. I've attached a few pictures of what I would propose it look like. The upper display portion would be 35-5/8" wide x 24" deep x 18" tall which would amount to a little over 75 gallons. I was really limited by space for the refugium/sump since the skimmer would need to fit in between and still have an adaquate depth for the refugium. As it's drawn the depth is only 8" which yeilds just under 22 gallons. Here's a cut away of the sump/skimmer. The plumbing would drain to the back center baffles and flow over into two 4" socks and into the skimmer section. Then the water would flow through the opening in the "wall" into the refugium area along the front. The "wall" would be opaque (probably black) to hide the equipment but is clear in this picture to show the functionality of it. The water would then flow back through the "wall" to the return pump section. There is enough room in this area to fit at least one reactor, maybe even two if I'm lucky. I debated painting the middle section in between the display and the refugium to keep the focus on those two areas, but I'm not sure yet. The stand is only about 15" tall and would have either one deep drawer or two shallower drawers for supplies, or possibly doors so that it could house electronics/dosers. The total height would be about 5' tall. I'd like to know your thoughts on it. If there's things that I'm overlooking or should rethink. Also, I have two of the curved pieces of glass. I was considering making one for myself and one to be sold. How much would you pay for a setup like this? Does it appeal to you at all?
