Help with SPS water flow for 65g.

I have not been happy with the tank flow in my 65g lately and need some help. I am using an Eheim 1262 for my return, and have three Sicce Voyager 3, and one Voyager 4. Two of the four power heads I run on Sicce's Wavemaker.

I have my SPS on a ledge half way up the tank. Two of the powerheads are mounted up high in opposite corners, pointed down towards the colony, utilizing the wave maker. One is running 24/7, mounted lower in the back of the tank, creating movement around my rock work. The last is mounted up high, running 24/7, pointing down towards the colony, at a different angle than the rest.

In terms of in tank movement, I am at like 5600 gph with just powerheads. The return pumps adds another 900 gph. This would total 6500 gph in water movement in my 65g. I figured this would be sufficient.

I am trying to achieve more random, turbulent flow; as opposed to laminar. Any thoughts on repositioning the powerhead to achieve this? I could buy a 2 way AC splitter, and place all 4 powerheads on the wave maker.

Now I do have a Sicce Voyager HP 7 on hand which puts out 2800 gph. That's more than 2x that of the Voyager3. I could use that and replace one of the other powerheads, but it's such a beast that I think it may be overkill and blow my clowns clear across the tank.

Any input would be appreciated.

Here is a quick pic of the tank for reference. FYI....one powerhead is not pictured, but is placed just to,the right of the overflow box pointing down towards the colony.

Get rid of those pumps and get 2 mp's 10's or 40's turned down would alleviate all your problems.

Yes....that would alleviate my problems. But for now I am trying to use what I have on hand. The Voyager 3 and 4 can be tuned down by turning the front disc and create a wider flow pattern. I am just looking for some ideas on powerhead repositioning and utilization to keep my SPS happy. Noticed a bit of tissue recession at the base, and figured that my flow may be the culprit.

Thanks for your help.
