Closed loop manifolds (CLM)- water

for folks interested in reading more about teed (top perimeter closed loop) manifold's, I'm keeping a list of some threads that include discussions of it here.

Best of luck and life to all

So this is run off of a return pump from the sump proper then?

I was wondering if I could run my return to the tank on a set up like this and then I could use the two bulkheads that were drilled for returns to feed another closed loop through an OM four way.

this would save me about 1400.00 on Tunze stream pumps for the tank. DO you need ball valves after every T? I am still unclear how the water is distributed equally among all the inlets back to the tank.

Water would take the path of least resistance right? so why would it make it all teh way around if some restrictions or control measures were not in place?

I am asking this becuase I dont know not because I am attempting to be contrary here. I really want to know because if this will work I can save a ton of money nad hopefully not sacrafice anything in the process.

it can be fed/driven by a number of different pumps/means... typically, though via a return sump pump, internal (display) submersible pump, a pump tapped into an internal overflow tower/well or closed loop pump drawing from a bulkhead in the display wall itself.

No ball valves are needed on each tee... none whatsoever. Too ugly, noisy and complicated. Overthought. Manifold tend to equalize flow by virtue of the closed loop. And equal flow is not even necessary or necessarily desired from each outlet. You can finesse individual flow via cheap fittings (reducers or flares).

that clears up some questions.

So this is something that can be done from the return pump then depending on size or a dedicated external pump plumbed from a bulkhead in the tank and fed back through the top mounted manifold

in the spirit of my sig to posts (not wanting to enable aquarists... but helping folks to help themselves)... I have to redirect you at this point, my friend

The link Amy graciously provided above takes you to an article with a literal illustration detailing the very thing you've asked...

... and many posts and pics in the links above (the very purpose for this stickied thread) will do the same.

You will learn much by being adventurous and self-serving. DO help yourself here, mate.

I have read that and I thank you. That is where the questions were derived from. I believe I understand the basic principle now.

the next step will be to test it in the bath tub here at home. Like all reef addicts I have a ton of PVC fittings and parts just laying around. SO in the next couple of weeks I will build a small manifold and run it in the tub to see how it behaves and then I will have an idea of how to apply this method in my new tank.

excellent notion, my friend... its so affordable and very illuminating to test the unit outside fo the tank to do much of the tuning

best of luck!

Is it really better to put holheads on a tank rather then a U tupbe overflow?? I mean if power goes out and your using a bulkhead wouldn't there be LIKE a MASSIVE flood! Or what or should the bulkhead be towards the top. When i take down my 55 gallon to replace the stand and such i am seriously considering putting bulkheads on. But then would i be able to run any type of GPH i wanted? I really want to put a inline pump at about 800 GPH and then do a cloosed loop for the return. Is there anywhere you can point me to learn more about this like a article more indepth. Or can someone correct me and teach me.

there is much to say here, my friend... and much of it is rather fundamental and easy to find in a good search of the RC archives, wetwebmedia.com archives (see plumbing articles and FAQ)... and good books (do keep at least a few on hand).

Also... I see that you are in PA state... we have several good hobby clubs where you can visit and see pics/local displays for the clearest illumination of these plumbing questions.

Do check out the club forums... We have Pittsburgh, Philly, central PA, etc

best regards, Anthony

ok, thanks. Well the whole thing i have is that i dont want water everywhere. And i guess it was you that wrote the article stating its a risk you have to take and a standard U tube would sometimes fail. Would i be able to setup soo that theres 2 outlets coming out of the bottom of the tank??? Or would it put to much stress onto the bottom of the tank soo it would break.

ratimpulse... could I trouble you to please start a general thread on this/your topic outside of this one? I'd like to keep this one uncluttered as best as possible and for the purpose of the stated topic (manifold links).

There are many U-tube discussions and siphon overflow threads... do help yourself to reading some of these before you post for a clearer idea. In short... drilled overflows are very (!) safe... and siphon overflows really are not.

The path of least resistance is all of them. It's a dynamic situation.
But, yes, there will be more flow closer to the positive pressure end (all things being equal, that is).

To any/all folks considering on posting to this thread... let me kindly ask that you start a new thread elsewhere or PM me, unless your comment refers specifically to the list of links in the very first post of this thread.

I'd like to keep this thread open for that reason alone.

Else we'll have to list the this thread of links in the links list itself as a link of useful information Er... somethig like that. Silly

with kind regards, Anthony

Anthony,
Great thread.
Have a question to ask and hope this is the right place. I looked at the above links. I was wondering how many outlets I would need on a 75 gallon tank? The manifold will be run off a closed loop. The pump on the loop will be a sequence dart. There will be a hayward electronic valve on the loop to switch the flow from the left side to the right side. My loop is actually split in halfs. My plumbing will be 1 inch in the tank. I was planning on 8 outlets. Should I reduce them to get better velocity or leave them as they are? I am trying to recreate a shallow reef area and will be having sps from the shallow reef zones in my tank.
Thanks

I hate to have to do this... but this thread is now closed.

Wellington: you have been PM'ed an answer, mate. Although this question has been answered in the threads above. No worries overall.

I just don't want to see this thread become unnecessarily large/long and cluttered with extraneous posts that are answered in the links above, or are better asked in new threads.

Otherwise... it defeats the purpose of having a list of links!
