Help needed on current for pleco caves

[rage]

when placing caves in center of fish tank, where do you placed the powerhead at? Behind, center or front of the caves for the current to flow ? Thanks.

I place my power head at the back corner of my tank.

I would let the current flow across the entrance of the caves.
