So im considering building a tank for a corner, the questions I have is should I try to make it just a triangle or more of a pentagon? Also how would I know the angles to get the glass / acrylic cut to? as well as what length i would make the 3 viewing panels? I am also clueless of how I would make a frame for it. another question is would it be easier or more cost efficient to use plywood for the sides in the corner? I want the Length & Width to be 48x48. Any and all input would be appreciated.
