This bad boy will cover an all/glass aqueon overflow. It is too tall for a 75 but is darn near perfect for a 65/90 or 120 megaflow overflow. This is the only one I have at this size. It is just under 20" tall and 18" wide. It projects 10" into the tank including the overflow.
We put it in a 75 gallon tank at the LFS and it fits that dead space perfectly between the overflow and side wall. It is just too tall for the 75. A few inches would need to be trimmed as it would stick out above the water line. I really wish I would have brought my camera to take a pic. While talking to the owner we both thought it was almost the perfect aquacape for that half of the tank. It left 8" for a sand bed for an open look with maybe a small aquascape.
I will not be able to make another one this size. It didn't fit in any of my kilns. I had to pay a friend to fire it in his monster kiln. It was the only thing in the kiln. I can make them smaller but right now I will not be able to make one as detailed as this for a long time. I can do the hieght with minimal aquasculpting. Or short and beefy. But not tall and beefy.
Bill from Midwest Saltwater will be bringing this to the Midwest Marine Conference for people to check out. Pictures never show everything. That is of course if it hasn't sold by then.
Enjoy the pics and imagine how cool this would look in your tank.
