Who rates skimmers

That wasn't what I asked, so I will rephrase, if I throttle back a Dart to 3000 gph and make the outputs disperse similar to a tunze or vortech would they be similar?

Yes and no, same flow rate different velocity. The lower velocity and greater spread creates an advantage as simulates natural water movement better.

So we agree that if I could make the outlets of a Dart replicate the Tunze/vortech with the dart throttled to be the same as the flow then we would have identical flow?

well not quite. A propeller pushes flow outward so it would take more than simply matching nozzle size, you would need some kind of special adapter on the dart outlet to produce the same results, but if that was the case yes I believe the results would be identical. Other than one uses 15W and the other uses 150W.

Seems strange you want to confirm this so badly, do you have a point you plan on springing on me once I agreed?

Of course.
