			 Toss up: closed loop system OR oceanmotion OR vertech mp40 for a 200-240gallon tank.  
		
	
		
		
		
		
		
	
		
		
	
	
	Cant make up my mind, closed loop + or - oceanmotion, or 2 vertechs?  |

			 depends on your rockwork. If really packed, then maybe closed loop, but if fairly open, 2 vortechs opposing each other should work. I've got 2 on my 120 and the fish and corals love it.

			 I'm sure after a while you won't notice the Vortechs but take a look on OM WaterPix forum for some clutter free CL tanks.
