Flow accelerator swirl educator

[jason604]

Does any1 have experience using a similar product as these flow accelerator swirl eductor on fish-street? Planning to use 2 of these as my return via a T to increase flow in my new tank build. Are they efficient and easy to maintain?

Used one until one of my shrimp or fish got sucked into it. haven't been motivated to try it since

It's for pushing water not sucking tho? Unless ur return pump turned off and it siphoned. But I am going to put a check valve on my return line to prevent this

I have them on my tank.Haven't used that brand but if it is the same principle they do work to increase flow.

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.

water gets sucked in from the back side, hence how these work, if a fish is swimming near your loc line return in the display tank, there is a chance he will get sucked in - just like mine did.

but sometimes this aquarium is all about taking chances. it seemed to have worked for me though!

Ahh kk. I guess I'll just stick with the typical flared nozzle then.

if it gives you re assurance to try it... it was a tiny little fish - if you have it - give it a try. I know I wasn't exactly blown away by it
