Pump is strong no doubt. Calculated jet nozzle velocity there is up around 10.0-10.5m/s based on the flow rate being seen in that test. Peak possible velocity with the MD-30RZ is around the 12.5m/s mark, but only through restricting volumetric flow rates to a mere trickle (~1LPM) with the restriction required to achieve that.

Still, even with an Eheim 1250 in a full assembled 1/2" system the Storm block's jet velocity is around the 5m/s mark, while with the Iwaki MD-30RZ on a Cascade the jet velocities were around the 6m/s mark.

It's not really possible for me to eke out significantly more velocity without choking flow rates to a near stand-still.
