Drilling tank

[ree-fready]

I have a 135 gal. as you do with the over flow drilled in the middle of the bottom close to the back wall. I wish I had thought it through a bit more because I would have done it diferently. When I move I will be buying a new tank with the overs and the inny`s drilled in the back for many reasons one of which is neatness inside and outside the tank. I have a overflow box around my down pipe that just takes up way to much room that could be put to a much better use. Repost if you want more reasons.
