75 gal tank flow

[roundman]

I have a 75 gal tank with a karolia 4 and 3 now. I am looking at adding a closed loop with a mag 9.5 to a 1" scwd with 2 outputs. I am going to put the outpputs in the center of the tank and have them go out from there with the ph in the back corners.

Will this be to much flow or ok? This is new for my tank and just not sure.

Thanks for any help
