I think I know what you mean. Use the front panel to dress out the tank. The front panel edges should cover the seams as seen from the front. Ditto for the tank bottom. Standing in front of the tank, you should not see other panes.ammerman19;568265; said:k makes sense. Does it matter which sheet is on the inside? It would be the easiest to clamp with putting the side piece in between the two long ones. Does this make a difference in the stability of the tank?
