Works Great By David on 2/6/2012

I bought this to use with the Vertex UL-15 reactor that is several feet from my sump. I run carbon and GFO. Perfect match for the Vertex. With the ball valve on the Vertex wide open the GFO tumbles vigorously without causing a storm, close the ball valve a bit and get the perfect flow. Pump works great.
