For those of you who have had the chance to build a stand from RedSea... Does it have a little wiggle to it with and without the tank on it? I bought a peninsula 650 and I built the stand without the back stationary walls (since it was going to be right next to the wall) in the direction on how to build the stand the photos show that the back doors are above the ground and are screwed on by two screws I just dont think three doors will do much for support since they are above the ground and are more for looks since its a peninsula.
