Plumbing, A few new Questions

[mark]

Running somwhat similiar (2-2" overflows w/Dursos, 1" return, CL with 2" in, 4-1" out). My tank is eurobraced as well but just along the long length, no bracing on the sides and thats where my overflows are.

Can't tell fr your photos if your bracing on the sides but something to consider is put a the overflow tower on the end (from your picture, swap the CL and overflow placement).

Also for a return pump, since you are planning a CL, you can rely on that for circulation and scale back on the flow through the sump. With the CL providing the flow in the tank, really running any more gph than the skimmer can handle is just an extra.
