Koralia's 1400 too much?

I have 2 1400's in my 75, placed on opposite ends about 1/3 the way down facing each other straight across the tank, pointed slightly up. They don't even move the sand. Now I don't have anything but an eagle eye and some GSP, but there are definitely parts of the tank with high, medium, and low flow for all kinds of coral. I think the problem is that you have them pointed down. With the right placement I don't think that's too much flow. Then again I am a total newb, so take my advice with a grain of salt.
