Plumbing...suggestions? Added a drawing...

Ya, I went and found Herbie's original post on Reef Central. Cool idea. I think I'm going to go with that. I think I may just do a u-tube type return as well instead of drilling a return hole, but what are the pros/cons?

I don't know how to make overflow "teeth" in my glass panes though...I imagine the teeth would just break off?
