Glass cuts

[Funky_Fish14]

Tanks built with 1-piece trim, like say a hagen, oceanic, perfecto, or all-glass tank, will have the front, back, and sides, resting on top of the bottom pane of glass. (there may be some exceptions with shape tanks or drilled tanks, but im referring to 'boxes').

Uneveness can definitely cause cracking in any build type or fasion. It is always best to make sure you have a proper installation surface anyways.

When building your own tank... any custom tanks I have built myself or have seen built at the glass/tank shop I worked at, or ordered myself from other builders, always have the sides, front and back, around the bottom piece. Even if you are adding trim after, if its cut-to fit trim, I still recommend going around the bottom.
