water movement - which direction?

[reefmagnet]

Ok, I have to set up my powerheads soon, I was wondering how should I set it up? Should the powerheads all face one direction so that the water hits the glass and circles back? Or should one face the left, the other the right direction etc.,?

I have ordered 4 submersible powerheads maxijet 1200 to be exact. Im just not sure what is considered good circulation. I figure as long as the water is circling around the tank, that'll be fine. they will be pretty low facing the Live Rocks and Corals.

You can place them anywhere you like, but it's best not to point them directly at any corals as the high velocity flow can damage coral tissue.

If you point them at each other, or direct them to bounce off of the glass or rockwork you can get some nice, random flow patterns.
