Yes, yes, it sows more difference.

But I really prefered some more ilustrative testing method, I havent have time to poore over hydraulic power comparison and thesis.
For example, results of C/W for at least 4 pumps (eheim 1046, 1048, 1250, and one very powerfull pump). So the viewers would se what to expect form pumps with simmilar characteristics.
