HELP WITH FLOW 37 gallon cube. (Video to show)

[Reeferburns]

Hi, I have a 37 gallon cube style aquarium with around 50lbs of live rock. I’m running one marine orbit wave maker at 660 gph with a flow style of a wave. Then I also have a 530 gph powerhead at a constant flow. I’ve currently got Xenia, GSP and a green bubble tip. I wanna add sps and lps corals in the near future. My GSP isn’t saving around like I see in a lot of other peoples tanks but my Xenia waves around crazy and I’m just scared that one coral might like a lot of flow but one might hate it and die. Also I feel that my placement of power heads is wrong I just feel that I can’t find the right placement or even if I have enough flow. I’m going to leave a video below of my setup. Any help would be much appreciated! Thank you.
