Powerhead PLacement

Anyone have any opinions on the best placement of my new powerheads for optimal flow. I have a 120 Gal tank with two rock piles for coral with a bridge of rock in between. I plan on getting either 2 Koralia 1's, or possibly 2 Koralia 1's and a Koralia 2. Basically I'm trying to increase my water flow and kept my detritus suspendedlong enough to be taking in my overflow to my sump. My return hoses from my sump both have nice flow on sand level. Any ideas of placement or better ideas of what powerheads to use would be great.

Do you have any powerheads already? The reason I ask is because if you dont, I would go for a lot more flow than that. I have two Koralia 4's in my 75, and could easily afford more flow than that. You can't have too much. As for placement, I would do what ever allows for the most particle suspension (no detritus sinks on bottom). I have one on the right side (rear) pointed at the one on the left side (rear) that points to the middle front of my tank. It allows for a circular motion around my rock pile. Many recommend as random a flow as possible which makes sense. I have also heard that wavemakers do a good job suspending stuff.

I like my powerheads up top and at opposite ends of the tank. High flow in the middle and it will work itself out from there.

I aim 4 powerheads to converge at the middle. The Koralia 1's will be way too small. I have 2 of them and 2 MJ1200's in my 54 gallon and I wish I had went with 2's. I would get at least 3's if I were you.
Whether you think you can... or you think you can't... you're probably right!
