The 5 internal fins form a set of spiraling channels. As the water flows through the nozzle, the channels draw the stream of water in one direction or the other. The small amount of interference at the base of the Eductor causes the stream to randomly change direction as it exits the nozzle.

    I purchased one of these for my Biocube. It worked very well, but wasn’t tight at the loc-line connection. I contacted them back and immediately they told me they would make me another one. He went as far as going to a store in his area to measure the point of connection on a tank. He then made me a revised part and shipped it out to me at no charge, and didn’t want the other one back. It’s very hard to find customer service like this these days. I would recommend this product for someone looking to vary the flow in their tank. You can see the surface of the water change.
