So what I mean by my last post, i took a screen shot of your stand, i circled on the right where the weight should be supported on all 4 corners. And on the left i drew in a 2x4 or whatever sive wood was used on the stad to fill in that void. That's called a jack stud and that is used to support the weight of the tank. As it sits right now the weight is only being held by the screws that go through the outer ring of wood into the existing upright posts.
I hope this makes sense.
