hydor koralia question?

[rodi]

I just prurchased a koralia 2, it claims to move 600 gph. My power heads say they move 200gph and seem more powerful. Is there something wrong with my new koralia or is the flow of powerhead just more focused/concentrated?

the other ones are probably moving a smaller area of water than the koralia.
for instance a lot of PHs will have the hole that comes out of the tube in the direction of water flow over the koralia which has the propellor open in the direction of water movement.

+1 i had the 2's and it seemed like my marinland 1140(300gph) pushed more but in reality the output nozzle was alot smaller and thats why it looked that way.
