Opinions on my flow pattern

[Squadir]

Hi guys and gals,
just wanted to get an opinion on my flow setup, I'm thinking this should create enough flow and turbulence needed for a reef tank but opinions/suggestions are welcomed. Tank is 48L x 20H x 18W (75 gallons) and is/will be SPS dominant

TOP VIEW ....excuse my MS Paint skills

Grey outlines estimate rock placement, this is an old pic showing the bare aquascape, the plumbing has since been done over and is on the other side

Return is around 500 gph when I used the flow calculator
A- 550 gph Koralia
B&C are both 1050 GPH Koralias

C is pointed slightly upwards, A is pointed straight across and is 2 inches from the surface, B is pointed slightly downward and the return is straight across at around 2-2.5 inches from the surface.
The return and powerhead C create the majority of the surface agitation in the tank.

Any input is appreciated.

Looks good to me. However I have found that everything looks great on paper. It's how it actually performs when implemented. I find I have to move mine every once in a while to accommodate a new addition or help increase flow in another spot.

Thank you.
Funny you should say that, I just finished moving the 550 pH to help a dead spot. Its now on the right wall facing straight across and upwards. Flow is dramatically improved with that one move.

As corals grow they will impact the flow, upgrading/moving powerheads around is a must.
