I've got 4 on my tank and love them. They definitely provide a LOT of flow.....I use a Pan-World 100PX-X through an OM-4way to power them.

They push and suck. They're engineered and designed specifically for mixing fluids. That's what eductors ("flow accelerator" is just a marketing term for reefers) do.


EDIT: oh, i wouldn't recommend their use on a return line, though. You need significant GPH (but we're not talking pressure-rated sort of force though) to make these operate efficiently. Unless you have a powerful return pump, don't bother with them. However, I do wholeheartedly recommend their use on the dedicated closed-loop line....works fine for me in this setup.
