75 gallon tank No center brace

I was wondering if anyone had suggestions on how to cover the top of the tank. There is no center brace so I don't know what to do.

You could use fluorescent light diffusers (egg crate). Won't help with evaporation, but will give you something to set the light on, and keep occupants in the tank.
