Eductor/Pendcutor/Flow-Accelerator Discussion

I ran one with a mag 9.5 and it worked, not the 400% they claim on the box, but I would say a 200% increase probably.

 

I run two of these off two ports of a Ocean Motion valve with a Reeflo Hammerhead feeding them. I have taken them and drilled the center hole out bigger to let more volume of water out the port. These are on a 1" bulkhead and I am real happy with the amount of water they move. If you don't attach the coral to the rock good, this thing will blow it right off in the sand. Jason McKenzie uses these too, as he is the one I talked to before I bought mine.
