I read the whole thing & it said onto not on top. When putting say the back piece on you silicone the edge of the bottom pane, then align the back piece with it leaning back at an angle, as you bring them together you tilt the back piece upwards to make it 90 degrees to the bottom.
When you build a tank you want to have 1/16" of silicone in-between every piec of glass.
