Yes and no. It's built-in to the tank itself (no sump underneath). It's similarly configured to a Biocube or similar - chamber in the back of the tank. Water flows over the "teeth" into the chamber, and gets pumped back in. Room for a skimmer, and/or a small refugium.
Brian ran this tank at home for several years -it was pretty when he had it.
