| I am doing exactly what you're talking about. I have a 4' 150g its 30" tall. Its a perfecto brand. the bottom is tempered so I drilled the back with 4 1" bulkheads and a horizontal overflow. I built mine out of black glass with no teeth, its 34"x 6"tall and 4" front to back. it is a deep tank but I plan on having rock work built up rather high. mines a work in progress hopefully i can post pics soon.
