The Corner-Flo 120 gallon aquarium utilizes the latest advanced-design water-flow technology. It features distortion-free glass and is silicone sealed to prevent leakage. Engineered to deliver perfect circulation and maximize water flow to the main filter system, the Corner-Flo eliminates dead zones, while minimizing flow noise. Water is drawn from the surface and bottom levels at an unprecedented rate of up to 700 GPH. The included plumbing kit contains all necessary bulk-head fittings, drain, return pipes, and dual Loc-Line outlet nozzles.
