I picked up a 40 gallon long tank (48" long) which has no center brace. I cannot tell if there used to be one. Does anyone know if there is supposed to be one? If so, I guess I would need to get one just to be on the safe side. Thanks!
I have an old 75 gallon that I've had for 11 years and it was an old tank when I got it. Has much thicker glass than the new ones today. Never resealed it yet and have had no problems with it except for all the scratches.
