I am going to disagree with you all for once, my LPS do NOT like the flow in my tank at all, I can only keep my frogspawn and duncans happy, my torch and two hammer constantly have me think they are going to be dead, I havent lost any yet but they arent happy campers.
That being said, if you are keeping SPS I will agree with the above posts, if you are keeping LPS you might be overdoing it.
