This super-efficient overflow aquarium system combines a custom Perfecto aquarium with Marineland's advanced water-flow technology. Engineered to deliver perfect circulation and maximize water flow to the main filter system while minimizing flow noise, the Corner-Flo eliminates filtration "dead zones". Water is drawn from the surface and bottom levels at a rate of up to 700 GPH, providing the ultimate in circulation efficiency. Silicone sealed to the back corner walls, the Corner-Flo components are protected and out of sight. The front section is removable for easy, convenient cleaning.
