ok I need ideas on how to do this

[Delphinus]

I can't offer any ideas, only thing I can think of to say is "Man you are nuts, that's just Stir Crazy."

Honestly, if the center brace is that offensive to you, wouldn't it just be easier to order a new custom tank and tell the builder "oh and BTW there must be no center brace." ??

I'm having myself nightmares just thinking about removing a brace on a fully stocked tank. BUT ... it's your tank ....

good luck...
