Then, how come cannister filters place the media on the intake side of the
impeller assembly - isn't this effectively the same as reducing the input
flow? I understand that this is done to give suction, rather than pressure,
inside the cannister - making any leaks less of a trouble, but at the
expense of the motor? What am I missing here?
