Description

The Reef Flow 2.0 4000 is a compact, high flow device for the home aquarium. Measuring only 2.2 inches thick (including the external magnet) by 1.9 inches in diameter, the 4000's svelte size doesn't seem like it could be capable of the over 1056 gph of precisely controllable flow it puts out. Flow can be adjusted via the 30-degree adjustable head, the three (included) interchangeable nozzles and the three different flow programs you can choose. An industry unique, flow through design helps cool the unit while preventing calcium and detritus build up on the innovative impeller.
