This is certainly true [the flow patterns I mean], but the fact is that it does not cause issues unless things are way out of balance. This has to be the case, otherwise those aquarists who have maintained large tanks with minimal flow or even no filter at all for decades would have killed off all their fish long ago. And, don't forget that fish can swim where they want in the aquarium, to avoid what they don't like.
It is also perfectly true that without plants, filtration is much more significant an issue, as I've often written.
But it is the fish in the tank that is the guiding factor. Different fish require different methods.
My initial response addressed the specific
case set out by corina savin.
