Help with flow

[PghReef]

Trying to figure out some flow before corals go in. Tank is a standard 90g 4ft by 18inch. Scape is pretty much set. Tank will be mixed reef with a lot of euphyllia and other fleshly moving corals in addition to sps.

I have a reefwave 25 on the face right that I have set to 100% constant for now. Wishing I bought the 45, maybe future upgrade. The corner overflow nozzles pointed back at the reefwave.
I have an mp40 on the backwall but am unsure of best placement so I dont blast away corals or have issues with it blowing sand from bouncing off the front glass.

I also have an mp10 I could add to the mix sitting dry atm.

I would try the 40 on the opposite side of the reef wave and maybe the 10 where the 40 is in the picture. If the mps start moving too much sand you can turn them down.

Also the scape looks nice.

I'm trying to keep the big outside part from being on the visible side there where I walk in the room. Partially for aesthetics but also so my kids dont knock it off and play with it.

Do you think there would be any benefit to putting it on the same side as the reefwave but maybe halfway down and toward the back and then use an mp10 or 2 on the backwall? Or would this create to much flow behind the rockwork and to little in the front?
