I’m curious after watching yet another reef documentary. A lot of discussion goes on about flow and what is best, I’ve noticed with seeing the corals in the wild that often the water does not move fast but is strong. Is it possible to create this flow with power heads in our tanks? Every powerhead I have bought moves the water well but is moving the water quickly more so than strongly. Anyone have any thoughts on this?

They are slightly less common now than they used to be, but many have replicated the powerful nature of water in their tanks- if you're interested, two common ways are waveboxs or carlson surge buckets.

I think you get something similar with a gyre. BLAST velocity across the top where the corals are not. Strong indirect flow back to the pump where the corals are.
