Lets Compare Overflows

Currently trying to decide between 3 overflow configurations to get water to the sump via a Bean Animal setup on a newly setup 135 gallon glass tank. The overflow will be on one of the 18"x24" side panels, and now the last bit of planning is which overflow configuration to use.

Currently I'm between 3 configurations, all of which will run a BEAN ANIMAL PLUMBING CONFIGURATION (this thread is not about how to plumb, but about the overflows themselves);

1. Glass Internal Overflow Box - C2C and pipes straight into the side of the tank.

2. Glass Internal + External Overflow Boxes - configured like a Ghost with the inner box being low profile, and the external being larger for the piping. In this instance, relying on GE SCS1200 Black silicone to build and mount the boxes. The internal box will still be C2C. External overflow will be approximately 15" Long, 6" Wide, 8" Tall. Both constructed totally from 1/4" glass, and the edges I will polish after assembly

3. DIY Ghost Overflow - Residual acrylic from my sump build, or new black acrylic for the build. Same sizing as the external box above. My only concerns with this configuration are; the bottom giving out of the external overflow box (I don't know if that is a common issue, but I know normally acrylic tanks need the bottom fully supported), and the bulkheads leaking. If you were doing it in acrylic relying on bulkheads, use 3/8" acrylic?

I'm personally leaning towards the glass internal + external overflow configuration made from 1/4" glass and GE SCS1200 Black, but I am trying to take every precaution possible to not have my tank spring a leak at some point. Which would you guys do, and why? If anyone has any personal experience fabricating the different setups, I would appreciate feedback from your experience and I know everyone likes pictures :lol2:
 
I build an internal ghost overflow box with an external acrylic main overflow box for my 120 gallon system. Given the small size of the external overflow box I don't see any need for it to be supported.
