How much flow?

I've read where flow in our tanks is important for proper nutrient distribution and algae prevention.

I have a 60g and two fluval canisters. The outputs are at opposite ends of the tank which is creating a nice circular flow on the surface. However, I was concerned that I didn't have enough flow at the bottom of the tank as all plants do not sway.

I bought a Koralia nano pump and installed it on the end thinking it would provide gentle flow. Well, I don't know what type of flow I should have but I did not get a gentle sway, it looked like blowing branches from a thunderstorm.
It just did not look natural although the fish seemed to like it.

I thought the nano was one of the smallest available so I'm wondering if using it is too much flow or am I just not accustom to seeing this type of movement in the tank? Sounds like a lot of folks use the nano in tanks smaller then mine so I'm confused.

It sounds good, just put the koralia closer to the bottom of the tank and point it upwards. regardless of where it blows it will circulate the water in the tank eventually and keep from having stagnant areas.

Thanks. Is it normal to create a debris field? I had leaves and particles going everywhere. Perhaps it will settle down?

I'd love to see a quick video of the flow inside somebody's tank. Not the surface, but what it looks like, say at the bottom. Any takers?
