Oh I agree. I am not thrilled about it. I got the tank used and the person before me had replaced the trim with no center brace. And the trim was in 4 pieces glued on. So I had to do something. So I removed and cleaned it and will brace it with glass or acrylic on the top. I'm thinking 3" braces on both corners and in center will hold. "I hope".edit: the removing of the rim would scares me. Editing the quote didn't work.
This would keep me awake at night! That's alot of water/weight.
