Is this considered overfiltration ?

If the current isnt blasting your fish around youre probably okay. You could probably cut back some and save some electricity though, at some point your filtration returns diminish and its not too helpful to run more filters.
I realize there are extremes when it comes to current, but don't a lot of river fish enjoy some currents to swim into? I have never seen what "too much" looks like I guess.
Most fish will enjoy a healthy current. I think of too much as when there are no slower areas for fish to rest or if the flow is so strong they can't swim against it. I doubt you'd have that issue, which is why i mentioned the idea of diminishing returns, that would really be the only way you'd be overfiltering your tank that I can think of
I think energy efficiency might be another way. one big filter vs like 4 or more hobs plus powerheads/sump pumps etc doesn't seem very efficient but it all depends on the setup and bio-load I guess. To each their own.
Rivers flow at 0 to 10 feet /second. Pumps (including some power heads) can generate flows at origin of up to 6-10 feet /second, even more for pumps if proper piping is used. With shear, that flow rate dissipates depending on angle and volume at varying distances from the source.
Fish that live in lakes or slow moving rivers may have some concern over being near an excessive flow rate, especially when it's operating as a stream much faster than surrounding water.
I agree, river fish like loaches that thrive in currents to swim against have areas on the tank to get some exercise and play. If a person has no tank decor such as rocks and wood to interrupt the flow then some fish are not going to enjoy that.
I am REALLY looking forward to building my corner pentagon tank in the next few months that will have a somewhat circular flow with obstacles to create low-flow, no flow and vortex flow areas. I think my fish are going to love it and have areas to enjoy for all mentalities.
