I'm using a mag 12 to run my Bullet 1 protein skimmer (I recently purchased the skimmer used). The skimmate isn't very dark or thick and the bubbles seem to be too large. Is the mag 12 capable of running the skimmer or should a different pump (pressure rated pump ?) be used? I've followed the directions that came with the skimmer but I can't get better performance....My old LifeReef pulled lots more from the tank than the Bullet 1.
