Flow

[Wretch]

I am currently running 2 Jebao wp-10s and a hydor koralia 750 in my 54g corner tank. I have just started adding SPS to my tank, I have about 10 frags now. I am looking at trying to get rid of the Koralia as it is huge and right in the middle of my tank. I am was thinking about getting 2 Jebao rw-4s as they are supposed to put out more flow then the wp-10s but are the same size. Then I noticed the price for 2 rw-4s is basically the same as 2 rw-8. Question is if I put 2 rw-8 in a 54g and ran them on low setting would it be too much flow?
