Sorry to ask an old question, but looking at your empty tank, can you explain the corners of the glass? It almost looks as if there's something holding the sides together? Or is it simply an illusion of the silicone on the inside. Only reason I guessed something holding it together is it looks like there's something between the sheets of glass where one butts up to another.
Also along the ridge is there anything on top? I know you went with starfire but it almost looks green, as opposed to the "clear" look of starfire.
