Powerhead Placement

[Drumachine09]

When I redo my nano, I am going to add a bit more rock. Basically the picture is what the structure will be like, looking from the top. The green dots are places on the rock that I would like to place small soft corals, such as various mushrooms, zoos, and the like. Where would be the optimal place to put a powerhead or two?

if you get 2 i would put one in the upper-left corner and one in the lower right (going by the diagram) and get a nice even flow in the whole tank

Top right corner from that diagram...point the powerhead 'off' though...towards a wall or the top water...not directly at the rock...

Would I only need one?

One is enough...just try to stack the rock so there's adequate flow throughout...
