Pumps have problems being too close to the beckett and wont restart propperly without taking the pump off the skimmer turning it on and then putting it in the skimmer body,
from what i have read they take a long time to start skimming again after a feeding and even the Moderators on the Zeo forum are replacing the injector with better US made becketts. so imo the Eheim powered NW cones ATB makes are a better choice.
