AquaC Urchin with Maxi-Jet 1200 In-Sump Protein Skimmer. **** PRODUCT MANUAL **** Finally, a small sump skimmer that requires no plumbing, fiddling with, or constant maintenance. The Urchin is the newest addition to AquaC`s line of innovative protein skimmers that utilize spray induction technology. Based on the popular Remora, the Urchin is a sump model that is suitable for small tanks that don`t require the waste-removing power of the AquaC EV Series. No plumbing required, simply drop in the sump and plug in the pump! Unlike most sump skimmers, the Urchin does not need to be raised or tinkered with to maintain the proper water level. For those with larger mini-reefs, try the Urchin Pro. The Urchin and Urchin Pro requires the smallest amount of sump space of any skimmer in it`s class.
