I am going to be setting up a 225 Gallon Miracles 5x3x2 (60x36x24). I plan on drilling for a closed loop as part of my flow plan. The tank is made entirely with 1/2" glass, starfire on the front panel.
Other than the 2 holes in the bottom of the overflow, the aquarium has 3 other holes already drilled for 3/4" bulkheads in the back of the tank. I will be enlarging 2 of those holes and putting a valve on the 3rd to keep for possible future use, maybe a drain...
The following diagram lays out my drilling plan.
Orange (Return) - Existing 3/4" bulkhead holes that will be enlarged.
Gray - New holes for Closed Loop.
Blue - Existing 3/4" bulkhead hole to be closed with a valve.

Any thoughts on the drilling plan are appreciated. Am I far enough away from all edges? Are each of the holes far enough away from each other to maintain tank integrity? Should I forget enlarging the 2 holes for the return and just drill a hole on the back center of the overflow and bring the return in there?
I will be running all Schedule 80 HD Bulkheads.
If I keep the orange holes, I know they are a little low and I would be using a pair of 90s to get the water closer to the surface to prevent too much drain back into the sump.
