What Jim said. Additionally, I successfully mounted a Tunze 6060 to a sea-swirl, and am sure the smaller nano-streams could also be so mounted. I have sinced ditched the non-controllable Tunzes for the less expensive modded maxijet stream.
The flow is much greater from these pumps due to the propeller rather than standard spoke-style impeller. At the same time, the flow is more diffuse, more spread out, rather than the concentrated jet of a standard powerhead.
