Thanks! When I decided up upgrade my tank the idea of an in-wall in my office got stuck in my head. I'm glad I went through with it. My #1 priority was that it was dead silent and except for the Jebao cross flow pump I am trying out it is.

I have been running mine with just the emergency straight pipe and open bulkhead since my previous post.
I run a lot of flow from the returns, so I saw strong turbulence in the external side of the overflow box, causing a vortex around the main drain that could suck air. To address this, I inserted a 1" 45 degree elbow fitting inside the 1.5" bulkhead feeding the external overflow box, and turned it to direct the inflow away from the main drain. This effectively prevented the vortex and air being sucked into the main siphon drain. The small hose in the top of the overflow lid is my ATO inlet hose.
Did you glue the 1" 45 degree fittings in place or not? I'm thinking of doing the same but can't seem to make it stay in place.
Just wondering how ya'll like this overflow? Pros, cons? would you purchase again? also, what is the big difference between this and the synergy reef ones besides price?
heh, old thread, but I cannot thank you enough!!I have been running mine with just the emergency straight pipe and open bulkhead since my previous post.

Here's a picture of the internal overflow and two 3/4" return lines:
And finally the 1" plumbing to the sump drains and from the sump 1" return, T-ed into two 3/4" lines.
