The Urchin is a compact sump skimmer that is designed on our popular Remora Hang-On. These skimmers share the same internal structure and are identical in terms of performance. The Urchin is designed to sit inside of a sump, and is powered by small pump approx 1200LPH. There aren't many skimmers with such a small footprint with this level of performance.
