I know the guy from buying Wyatt, and he wouldn't sell me a sub-par rack, he is simply moving up to a huge rack and has no need for this.

As far as it being too big for my 09, should I just keep him in his tank till he hits the 500 mark, or is there a way to section off the tub or simply fill it with enough stuff to make it seem smaller? He's currently in a 30 gallon tank but has enough plants and hides to make it feel much smaller, not sure if I could do the same for a tub until he hits the 500 mark
