Water Movement in the sump

Hey people,
I was just wondering if anyone sees a problem with the fact that there does not seem to be much water movement in my sump. I know there is some as the Mag 7 is at the opposite end of the 30g sump from the overflow. However, the surface water seems to be pretty stagnant. Is this alright??
 
I have a small power head pointing upwards to agitate the surface. If I don't, sometimes there is a nasty film/algae that appears after a week or two. Yuk!

eee
