It's not nearly as difficult to drill a tank as people think. Especially on one with thin glass like a 40B. HOB
overflows scare me lol. I'll never use another one. I had one lose siphon and the sump was the same size as the DT so it just overflowed the tank onto my floor until it had pumped at 40 or so gallons out of my sump onto my carpet. use glass-holes.com if you decide to try it. They sell the complete kit with the bit to drill it. The bottom glass is the only tempered glass on 90% of aquariums.
