[Where does the skimmer locate in the sump? I plan to keep mix coral but mostly will be softy. Thanks for all feedbacks.] said:[In the Pro series models, the skimmer is in the first section where the overflow enters, then the refugium, then the return pump area. On my model, the first section appears to be made JUST big enough to fit the skimmer, and it's an ASM-G2 model skimmer.]
