Here is my 38G tank without it's bottom plastic framing.
The black strip is just black electrical tape. Now, I do have a question about this setup.
The bottom plastic framing was broken when I bought this used tank. It has this construction - showing a cross section:
That's the actual plastic frame (end view) and I drew in the aquarium glass. This framing provides a recessed bottom where only the perimeter of the bottom glass will be supported. It's plain to see that there is no bottom support to the side glass, only side support. A lot of those wrought iron tank stands that are sold have only perimeter support. That puts a lot of pressure on the bottom glass span. I would think the tank bottom would actually bow down from the weight and pressure. Perhaps that is the design of it. It confuses me.
Perhaps this info will help (or confuse), others as well.
End result is that my 38G aquarium is sitting flat on it's bottom with no recess provided by a bottom frame. It holds water just fine and the entire bottom glass is supported, not just the perimeter.
Anybody have information on just why the bottom of so many tanks have this recess area?
