The seaclone is a 'hang-on the side" type so the water coming from the skimmer breaks the surface and I have a powerhead angled toward the surface. I was 'white capping' my water for a while trying just what you thought. The skim on the surface would just swirl around. Didn't help at all. I've seen angled the powerhead less since I was getting water on my floor lol
