I have just found 3 sheets of glass 6' by 3'.... what I am considering is making an L shaped tank... one section would be 6x6 then the other portion of the L would be 6x4 has anyone made a plywood tank like this??? with multiple viewing windows??
There were some L tanks around but none plywood that I've seen. Assuming you make it structurally sound shouldn't be a problem. avoiding flex with such a shape is difficult but not impossible. good luck keep us posted on your progress.
