Nice setup so far,

Take it for what this is worth but i'm slightly worried about your stand framing with just single 2x4's from what I can see.. 6 vertical with 3 tanks?

May be okay but I would hate to see disaster, just like a floor you wouldn't see anything short term of having the weight on all the tanks but long term you're going to have some bowing decreasing the structural integrity.

I think a vertical 2x4 weight capacity is somewhere near 500lbs?
