Sweet! Albert showed my your thread on the weekend and I went with the same setup (although 90G) after looking at your picks on the dual return out the sides of the ovwerflow. The only thing I did different was had black plastic put surrounding the overflow so it hides the plumbing.
Albert has the anti siphon on some of the tanks on the back and they seem to work great, you are considering not using that design though?
On my current 90 I have my return pump throttled back to maybe 1/4 so with this design even if it creates some headloss for me I still have lots of pump power left.
I look forward to seeing this tank up and running with livestock
