Thanks!

Actually the last picture is like you're laying below the tank and looking up (yeah hard to tell with my clear sand... ). there are 3 holes in the bottom of the tank. 2 are drains and one is the return. The return is divided into 4 and then pumped into the tank through a bulkhead in each side of the overflow. The water will flow over the overflow into that center section where it will drain through 2 stand pipes. Does that make more sense? It's hard to put all of this in writing!
