So, flow to sump won't be a problem. In fact, at full power ridiculously over board. Sump has a slight leak. Sigh. I think it's from where the two halves are joined together. What I get for getting cheap/used.

) Easy enough fix, just waste of time.
Fine tuned the Bean Animal, with 1.5" pipes handles the flow adequately and quite easily. Easily overkill. I'll post a vid when the return line is secured.
Got a problem though, the water level in the tank is too high. It touches the center brace on the under side. (It flexes under load....) I could let it be, another thing to clean....
I placed the top edge of the weir close to the top, maybe 1/4" gap to keep fish from going over
So do I just wait to drain and extend the teeth height with a Dremel? It's already bonded to the tank. Under the Eurobrace. That'll lower the water level I guess.
