I'm going to have to talk to him about it again... I have a couple of ideas for strengthening it, so I guess stay tuned!
Save yourself aggravation. Use the short ones for giggles. When you move the tank later on just buy 2 dowels long enough to go through in one solid piece, or better yet as Hoppy said pipe, so the only thing the screws and pipe brackets are doing is keeping them in from sliding left off the long edge.
