Step I - Size matters

I like the idea of a freestanding tank with room to view it from all sides (like in the ADA gallery, look here too).

Unfortunately, since I don't have the space, a corner would have to do. The size of the tank was limited by the furniture to 50cm, so I was looking for a tank that would give a large as possible viewing are and maximize the water volume. I wanted a 50cm cube liking its symmetry but when I positioned a cardboard model to help determine the height of the stand it didn't look so good. In the end I decided on a 50x50cm 40cm high rimless tank. At 100 lt. it is not huge but there is enough depth to it so that I can do something interesting...
