Best powerheads?

put a couple Koralias in that tank and the bamboos will think they are in a river.

the Koralia moves a lot of water and is efficient at it.
 
Will the peacock gudgeons, neon tetras and kuhli loaches be okay with all that flow? Thats why I figured a direct stream might be better, so that the bamboo shrimp can sit in the flow, but the others can avoid it if they want. Maybe just one korelia? Or maybe they will like the flow too.
