This is my first setup. I got this setup used from a guy that had things set up just as the pic shows. I'm concerned about weight. The tank does not fit the entire stand and leaves a several inch gap in the back. There's only one relatively thin cross board in the middle. Is this normal? It's a 55 gal tank with 80 lbs of and and plenty of LR. It worked for him but I just don't want any mishaps.
