Sorry for this noob question on building glass tanks 
What is the best way to seam a tank together? Here is the diagram thing...
I'm not sure if you can see the difference but if you do, can someone say which number is the best one?
Is it good to have a little bit silicon between the glass or should it just be on the inside like on pic 1.
#1 and 3 are a bit exaggerated but its supposed to show a layer of silicon between the glass while 2 and 4 show that there is no silicon the glass.
Any help would be appreciated
If this helps, the tank will only be a 12 inch cube tank.
Thanks!
