What I was looking for hehe!

I built one to the specs that he has on that site and am running it with a Rio ( I know, they Suck) pump, and is working great.
I modified my CPR SR-9 skimmer to accomidate it. I will post pics soon.

StoneyReef · 12-14-2003, 04:49 AM

but, does your sound like a jet taking off?

Pro_builder · 12-14-2003, 05:07 PM

Stoney,
No mine doesn't sound like a jet taking off. I can barely hear mine.
Here is the update to the setup. I will keep you informed on the gunk production.
So far so good.

I'm not 100% sure that this is how a mixing eductor works, could someone help me out? It looks like the water flows in the the T, forced through a smaller hole to make it like a jet, and then out through the other end of the T (straight line) in the same size pipe that it entered the T. The 90 degree part of the T has air sucked through it due to the venturi force of the water going through the T (causing a vacuum).
If that explanation is a little confusing here may be a better one: Water goes straight through the T, the flow of the water through the T sucks in air and places it into the water in the form of bubbles.
In essence you are sucking air into the water column (to go to the skimmer) without having to use a seperate pump to blow the air into the water. The only pump needed would be to push the water throught he T.
If this is true I may have found the way to complete a project I have been thinking about!

omg am i the only one confused....

Pro_builder · 12-24-2003, 01:49 PM

mnreefman
yes that is right.

skeletor121 · 12-24-2003, 02:49 PM

Glad I got it right. Since it can suck in air, I would have to think it would be able to suck in water. Maybe this is the part that I have been trying to build to suck water out of the refugium and into the return line so it will not have to go through the pump. Now that I know what pieces I can use to create the suction, maybe I can get one together and try it out. I don't have anything set up to try it out on yet. I am just piecing everything together before I start my tank.

If you are totally confused you can check my original post about the eductor.

I read through the many links and looked at the various diagrams, but I still do not get how the water does not go back throught he space indicated on the picture.
