Sun sun vs hydor koralia

Okay I bought a hydor koralia 600 powerhead Saturday. I recieved it yesterday. I also have a sun sun 800 powerhead in my tank. I know the sun sun is rated at 800 gph and the hydor is 600 gph but I can barely even tell the hydor powerhead is on. Put my hand in front of them both and can really feel the sun sun and barely feel the other. Is that okay or do you think there is something wrong with the powerhead? I bought it for more flow and can barely see any difference.
