Enough flow reefer 170?

Thinking about adding another power head to my upper right hand corner not sure if the bottom of my tank is getting enough flow of it would be over kill for a smaller tank I would want to angle it down with a low flow any opinions?

I have a 170 with no power head, just the return pump alone seems like enough but no SPS. I wouldn't think that a second power head would be needed

Yea I just feel like the two back corners are dead spots idk mabe if I move my one power head over to the back a bit more
