Flow vs filtration

I'm hoping someone can answer my question...

I'm having a bit of brain freeze over the flow in my tank. My brain is telling me that to get good biological filtration from my LR I have to have a lot of water movement. But 99% of what's in the tank likes medium flow and I'm worried I'm blasting them.

So my question is - does our LR biological filtration work better in higher flow or doesn't it make a difference as long as the water is "moving"?

Thanks for any help :D

Low-medium flow is fine in terms of actual biofiltration. However, higher flows will help keep the rock "clean" by keeping detritus (gunk) floating in the water.

base tank flow on inhabitants.
Blast rock work every week or two to remove settled detritus.

easy enuf. No need to overthink!
