Educators?

[Raibaru]

Can someone give me some basic info on educators please?

I'm having a hell of a time researching these things and I'm trying to find out just what exactly they are and what benefit they provide to a tank and water flow.

I've seen a few posts over on the DIY forum about people making their own and it's hard to follow them when I don't even know what they are to begin with. Not having much luck googling them.

Thanks in advance guys.

Search for eductors. No "a".
There is a big thread from way back entitled..."Eductors can be dangerous", I believe.
Not really dangerous though.

hehe, yea spelling things correctly goes a long way in trying to research them.

Thanks!
