I ordered a HOB overflow the other day. At first the neighbors probably thought I was crazy, yelling about how this thing sucks as I was trying to get it primed, however after I figured that out, I'm pretty happy with it. I was disappointed at first seeing a huge air bubble in the U tube, though in about 60s the flow through that tube increased so much that the bubble just flowed out. Mine I think is like yours, in the sense that it has one 1" output. Putting another U tube won't help with the flow. You need to have a dual output, or a larger diameter output to increase the flow.
A question though (not to steal the thread). Has anyone ever put up a 'screen' style thing in front of the teeth of the overflow? My flakes keep getting sucked into the overflow so the fish only have like 5s to eat their food before its gone!
