Would anyone be willing to attempt to help me make one of these?

http://www.reefcentral.com/forums/showthread.php?s=&threadid=503664&perpage=25&pagenumber=1

the only restrictions that I have is that I only have 3 inches to work with behind my tank... but from what I understand is that 3 inches is plenty of room for this...

Anyone up for the challenge? Not now, or tomorrow but in like 2 weeks... I need to get a return pump and stuff first and baffle off my sump/fuge tank...
 
looks like way to over thought to work well I prefer to keep it simple less chance of a woops and man does that thing eat up some room in the tank i would say no way ....much simpler solutions

Its definitely interesting. Almost looks like you could hit a musical note with that thing.

All things considered equal though, even if it works, there is no way I would have that much PVC visible in my display. Even with good coralline growth on it, it would be an eyesore IMO.
 
I made one before. It works to move water to a sump well, but doesn't cover enough surface area to keep the surface water in the DT free of dust. Melev has a nice overflow build thread on his site that I copied. It didn't come out looking as good as his but it works. I haven't had any probs with mine yet, but I think I'm gonna buy a lifereef for insurance.
 
I CAN'T use an over-flow BOX... I stated that I only have 3 inches behind the tank to work with, unless I drain everything out, and take most of the rock out, and physically move the tank... which is too much freaking work... I already moved the tank once... Not doing it again...

Why are these so scary? They don't over-flow your tank during power outages, and If you have a black background and use black pvc... you can barely see it anyways...

This is a simple solution to my problem... I don't have ROOM for an over-flow box, end of story... and drilling is NOT an option at this point... When I setup my 90g, sure, I'll have that one drilled... But it's not an option at this point..
 
Didn't realize that you only had 3" to work with.

The PVC overflow can absolutely over-flow your tank. Let me see if I can explain. They're kind of like CPR overflows. They can build up air in the *U* portion that goes over the tank. Too much air in that part will cause it to lose siphon and your tank will overflow. The solution to this is to drill a hole in the top of that *U* portion and install an aqualifter. However, that hole will need constant cleaning as it can clog very easily.

If you really wanna build one, drop me a PM. I live in Youngstown and will try to help you out.
 
Yea I was planning on using an aqualifter and stuff... I just feel this is my only option for where my tank is at without moving everything AGAIN. LOL

I'm still trying to figure out what one I want to build, there are several that I found but this one, and one other that I will try and find a link for are the ones I was picking out, though the other one can't fold and thin out as you need it to I don't think but it's design is much better IMO.


AHA! Found it... Check this thing... I'm not sure that this will fit though.

Here is the link to the parts needed and animations and full 3d drawings of the thing... Picture after the link

The one in the original link folds out so that the only space behind the tank required is the diameter of the pipe you use. That also means that the two inputs are spread out so that there are one in each corner. The one above need 2x's the diameter of the PVC as space behind the tank and does not spread out.
 
Ok, this is using the design from your original link. If you do it spread out like I mentioned above, the only portion of the unit you actually see inside of the tank is the to input sections that I have circled in green that would be in each corner. Now you can connect those two inputs with a PVC tube that's cut in half lengthwise like an upside down *U*. That's the purple line I drew. If that upside down *U* is right at the waters surface, we just created a coast to coast overflow.

Hope I make sense to someone :smokin:

I'm glad you understand. Again PM me if you want to get together to build one. I'm off every weekend, but busy this next weekend coming up
