which is how a 15w pump can do 1800gph. ahhhhh physics. without the stream's educter end on it, it would only be doing about 400gph. go figure.

time to play with some pvc and physics.

Um.. a Stream isn't an eductor at all, totally different set up it is a propeller instead of an impeller. a eductor uses water movement to create more water movement in a siphon type idea.

Thank you for the links. I will have to give one a try.
It appears to get good flow out of an eductor you need a pretty beefy pump.
I will be trying this on a mag7, I doubt it will be much good. But I plan on adding a closed loop to my system one day, which this eductor may come in handy for.
