I've read that corals need turbulent water flows and not linear/one-way flow. How important is this? I'm running a 10-gallon with a single powerhead (Hydor Koralia Nano 425) that seems to provide plenty of flow on the surface and in the water. However, since I'm only running a single head will this not provide the type of turbulence needed to keep corals?
