I have a 95 pentagon corner. I have 2 Koralla Evolution 1050gph powerheads now. I am having a hard time getting the flow to go where I want it. Im thinking about getting a Mp 40. My questions is will the Mp 40 get the movement everywhere? Then I can use the Koralla to supplement? All the vids I see the Mp 40 moves a ton of water and seems it moves everything in the tank.....as long as the Mp isnt to small.
