Finally got a chance to watch the video. Not something I can really do at work.
Looks great!
Maybe it will inspire me to do more than a few quick pics.
Am I understanding you are planning on using loc-line for the overflow?
Neat idea, since you can adjust the height of the water that way easy.
But knowing me, I would accidentally bump it down, which would drain things on the garage floor again .....
It is great that you will be able to buy/qt a set of fish, keep them separated during QT,
and then add them all at the same time.
Better for the territorial types that way.
I wonder if it would be nice if the smaller baffles were removable, or had a large hole you could plug/open.
That way, you can let fish get to know each other as you please.
Maybe you can rent out QT space to pay for all that Sch-80 pipe.
