Anyone build a Hang On Overflow??

[200gal]

Thanks Canadian Man. Was just wondering a few things. What size are the two flow tubes and what are they made of?
What size is the drain hole and tube running to the basement? I do have the basic principles of how to build it. I was also planning to plumb to the basement also. What kind and size of pump runs your return and what size is your return line? Is the tank in your basement raised much off the floor? What size tank were you running this overflow on? And by the way, nice job.
