Is Too Much Water Current Bad?

[Hulka9]

I can't tell if my current is too strong or not. It seems like the fish like it. almost like a treadmill. I have a corner with low current where they go when they want to relax, but the center of the tank is pretty strong. Heres my specs...

10 Gallon
Eheim 2213 (flow turned down halfway)
Marineland Penguin 150B

5 Peppered Corys
1Dwarf puffer
3 Amano shrimp

I have the eheim directed across the top of the surface. It gets pushed down against the glass on the other side and loops down across the sand. I can see the corys swimming to stay in place when they are in the middle, but they have to swim hard to swim through it. The puffer stays in the back corner in the plants and doesnt seem to have a problem with it until he comes out into the open. Then he gets pushed around in the highest current spots.

So can too much current be bad?

From what i can tell it still looks like the fish enjoy the current (other than the puffer, he hides in a dead spot). Only part thats annoying is the sand getting blown around.

Why do you feel you need so much current?

Im adding another tank in a couple months and want the eheim to be cycled.
