Tank was purchased used. The three holes on the bottom were covered with acrylic, and looked like sealed with silicon.
The silicon pealed right off. But the plate would not lift. It looks like they may have wedon 4 from the bottom hole, and not the edges.
So I'm posting a picture of one of the holes. looks like one piece near the hole.
