Question about Flow

[parkinsn]

So this thread has me thinking, among other things.

If you have a wave box or vortechs creating a wave, does this cancel out your other power heads, or does it just make for more random flow? and yes i know a wave box does not add flow just water movement. Any thought on this or links would be good.
