I'm about to purchase a 75 gallon with the brace in the middle. the Dimensions are 48" long 18" wide and 21" tall, I want to get a versa top for it, but do i need to buy 2 versa tops since it has the brace in the middle? Or Does anyone suggest a better top to put on it? I like the versa top, as this is what i have on my 40 gallon, and it has worked well for me. Thanks
