My tank has a tempered bottom so I am planning on drilling several holes on both ends. I really have never drilled for a sump and have always used overflows. I want to keep the plumbing on both ends of the tank rather then being on the back wall or corners like manufactures do, being that it will be see through. I know the surface skimmers across the ends should be fine.
I am planning on having 4 return holes on both sides. 2 about 6 to 8 inches off the bottom, and 2 just below the skimmer boxes. I have made an alternating current device, similar to how a SCWD wave maker device alternates the return flow to opposite sides of the tank.
The issue I am worried about is a siphon on the return lines when a power outage occurs. I'm thinking of making a a 5th return line with a u-bend over the rim, and capping it off about an inch below the water line. Drilling a small hole in the end of the cap to break suction once the water drops below the hole.
Does this sound fail proof? Any other thoughts or issues I am missing? It would pretty much drain the tank if the siphon break holes failed.

On a side note, anyone close to springfield/decatur have a 1 3/4" and/or 2 3/8" glass hole saws i could use for 1" and 1 1/2" bulkheads? Also, anyone good with working with acrylic or a router, to make the skimmer boxes?
