still, why? whats this for? whats its purpose?
I'm back from class...
Mayo pretty much got my idea down with that diagram. The only reason I asked the question was because I got to thinking about it yesterday and it seemed like it is do-able to me.
I want to set up a system with an external pump, but I don't really want the high flow of that pump AND another return, so I thought it seems like it could work for both. It does seem possible to me, but it also seems like more of a hassle than it is worth. Now I am thinking of using the Little Giant for closed loop and a mag 3 for return from the sump.
Thanks Mayo for defending my idea and not simply saying its stupid and no...

no offense, its still not a closed loop. ron was being fair and informative. also gave good advice based on the very little info that you had provided.
Closed loop or not he clearly understood what I was trying to get across.
Whether it fits the definition of a closed loop or not is something I frankly do not care about at all. And by the way, I feel that the term hybrid or semi-closed loop does make perfect sense because the majority of the water would be going on a CLOSED LOOP without leaving the plumbing.
What is the point of even spending time talking about the meer definition? Everyone understands that I was thinking about using one pump to both re-circulate water from my display and also to return water from my pump.

Wow!
Maybe we should drop the definition thing and continue with what you want to try now that we know what it is that you want.
Ron
if you didn't want people to criticize, why did you ask for opinions? Basically with anyone that told you it wouldn't work you start accusing them of being "critical".
ron was right on going to the definition of a closed loop--it sucks water through one tube and spits it out through another, with no break inbetween, thus no possibility for leak (other than faulty plumbing. He probably assumed that you have enough experience with water that just pointing out that your system wasn't closed (and therefore would leak during a power failure), would be enough to point you towards someone else.
Basically, without expensive check valves that may or may not fail, you WILL end up with a nano-mess. That's pretty much the bottom line.
You could probably just split your overflow into the sump so that only a portion would go to skimmer/fuge and the rest would just get sent back up to aquarium by the return pump.

CLEARLY NOT.
ron thought that you wanted two returns from the pump.
i thought you were trying to reduce flow through the sump without reducing flow in the tank.
and CLEARLY if ron thought it was a stupid question he wouldnt have posted at all or offered no advice.
im sorry ron. im just tired.

Thanks for all your support guys.
I have to member this user and be carefull not to answer anymore of his/her posts.
And Like I said before.
Sounds like jafoca sat on a tolit seat. (my sig)
Just got a bit sick of every third post saying "That is not a closed loop" So what? Yes, it does matter because it is not a fully closed loop there are things to worry about such as reverse flow from a power outage. That is why I posted this, not so my definition of a closed loop could be corrected.
I just went back and counted... four different people said "That is not a closed loop", and most did not post anything more valuable to the thread, hence my fustration. Again, I am not griping about people criticizing my idea, just people who want to debate whether or not this system has a closed loop of any kind involved. I have no interest in that argument.
And by the way douggie, both you and albin were correct in your initial assessment of my idea: the plan incorporates both maintaining high flow in the display, low flow in the sump, and multiple return outlets in the display.
Yes albin, you do know what you are talking about, and I am sorry I was not more clear in my initial post. It was just a bit dissappointing to have the first response to my question be "that is not exactly a closed loop, so no you can not do it".
Thanks to those of you who constructively contributed to this thread, especially mayo for that diagram.
