Crossflow cp-25 or cp-40 for 40 breeder

[Alazo1]

I have a 40 breeder sps tank.
Currently I have 2 rw8's on either side of the tank facing each other. There is also an mp10 blowing across the back of the tank. The flow is good but it's getting hard to place them due to coral growth.
I'm thinking of getting one crossflow to subsitute for one of the rw8's. Is the cp-40 overkill?.

thanks,
Albert

I would do the cp-40. I have one on 36 inch wide Frag tank. You can always turn it down if needed
