Interesting. Looks like the Spin pipe is specifically designed to be used with a much higher flow filter (ES-300? No idea on the lph/gph specs though) than what we're used to seeing on Mini tanks and the like, particularly the Eheim 2211~2217. The flow distribution should allow for much more efficient filtration of the aquarium water volume without giving too much concentrated flow. Well played, ADA. Perhaps we'll see some setups with Eheim 2215/2217s on Mini M tanks.
