Water movement question
			 
			 
			
		
		
		
		I have a 50 gallon tank with fluval 404 filter system blowing in the tank.  I also have a prism protein skimmer, which doesn't add much to the water movement.  Do I need a powerhead to add to my water movement? 
 
I have a few corals, live rock, anenomes and fish.
