Waterflow 180 gallon reeftank

[Rafaelpadro24]

Looking for some advice, currently in my 180 gallon tank I have 2 mp40's one on each side of the tank and 2-1" returns with Y split lockline. I have 2 large gyre that I'm not using. I feel I have a dead spot in the middle back of the tank behind the rockscape. I was thinking of using a gyre in the middle pointing some what down towards that area. Any suggestions on how I could use my wavemaker more effectively. Thank you for your feedback.
