greetings everyone
i am another who wants to use this setup, but need some help.
i have a non drilled AGA 75 gallon and at first i was going to do everything like beans design but now i decided to change it a tad. If i went with a glass internal overflow half the length of the tank (or 24in x 5in x 5in) and i used 3 x1.5in bulkheads with a 30 gallon sump, what would be the best return pump to use so that the flow through the sump is not too fast?

Matt:
I have a question about your proposed tank configuration: Your drawing ( which is very nice BTW...) does not show any trim or bracing around the top. Will the tank be an "Elos" style - or rimless tank? If not - you might want to model the trim/bracing on the drawing, and perhaps even do a cardboard mock up. I say this - because the access to the "intake trough" ( forgive me BeAn - I am not sure what to call it if other than an overflow) IS tight - should you need to remove anything. Just a thought ....( I only get one thought every 3 to 4 months T

Each box has two stockman variants of the durso, and I never have gotten it as quiet as I want. If I were to do it again, I would do as you have drawn with a single outside box rather than two, or at least put a third hole in each of the boxes to allow use of Bean's design. Make the box as long as you can and add an extra hole to the back of the tank if you can. Make sure that at only 5" tall your fittings will fit . I had to get creative, but then I have glass lids on mine with a 1/4" tee fitting in a hole drilled into the lid to further muffle the sound (makes the whole boox a durso, kinda, except you don't really limit the air flow).

bean,
quick question, my display tank is going to be about 6ft higher (top) than the sump which will be located in the garage area. question is, the sump is going to be 7 to 8ft over (to the side) from the display, do you think there will be a problem with the horizontal run of the system when using your draining method? vertical drop from tank overflow would be about 4ft then horizontal to sump about 7ft then 1ft into top of sump. thanks again. |

So what is the though on using a “U” trap? Someone suggested it earlier in this thread, but for me I am not sure I will be able to do a “beanAnimal siphon” drain. (I might have to stick with a durso given my situation). I would use a trap just because I don’t have much room, and would need to drop the drain pipe down past the top of my sump, and then back up over into the sump.
Would this be a big issue? Anyone using a trap? |

bean,
making last minute design changes, and have another question, i can't edit my above post, so here it is...... drains 1in, (3) in middle as per original, but i am thinking of running my 3/4in returns slightly higher than the drains on each side and run through the bottom of overflow coast 2 coast with a 90 then terminate with ??? thoughts from you or anyone else about the returns run through the overflow. any pics would be great. if it sounds good, is it wiser to run through bottom or straight out the front of the overflow. i am trying to avoid the over the top return lines. sorry for so many questions, but i am trying to get it right from the start. thanks Last edited by NVReefer; 03/13/2009 at 03:50 PM. |

My build
Thought I'd show you my build of this style overflow. In the UK we don't get sanitary T, so I used a 45 and a 45 T to smooth the flow. It stands off the tank a little further, so I placed the overflow at one end of the tank.
The only problem I've encounted is cavitation and therefore noise introduced by the valve halfway down the pipe. I'v now added a second valve at the bottom and opened the mid point valve fully. Now works silently. The overflow is almost coast to coast, but chamfered to avoid the front glass. |

what's the drain capacity you guys have? i have always told to shot for 3 to 5x of the tank volume in the sump. a single siphon will have ~2000gph or so (?), that seems a lot of flow through the sump. are any of you guys concern about the high turn around? or do you find a way to dial the flow down a bit any yet still make it silent? am i wrong to think that if the return pump is not powerful enough, the siphon will not be able to form because there won't be enough water in the overflow box?

Make the horizontal run slanted and use 2.5" or larger PVC to allow for air space. The vertical to horizontal transition should be gradual, not a simple 90. |

Sump turnover rates can vary greatly depending on your setup and needs. I prefer moderate to high flow sumps and refugia. |

bean
thanks for the replies,
yes, run the return through the back in the middle of overflow area, then 90 turn to exit the bottom of overflow into tank any ideas how to make a Silent drain with my horizontal run. i don't see me using 2.5in piping. |

Run the setup as a full siphon (a herbie) and hope it stays in tune. Setup the other standpipe(s) as emergency drains.

BeanAnimal, I have read thru a great deal of this thread and very much appreciate the work you have done on this subject. I am using the setup you described and I would like some input from you on a change that I made.
I recently started a new 90g build and put all of the details plus pictures in the build thread. http://www.reefcentral.com/forums/sh...readid=1561603 My change is a collector that I used to bring the three overflow pipes together to one so that I can use a filter sock. I do understand that changes to the system will effect the overall performance of it, but I Hope that this change will not be of the "critical variety." I would very much like your input before I glue it together. Thanks in advance, Joe

Since this is a constant ongoing debate in my mind, I'm considering again the original method bean proposed but perhaps not coast to coast but leaving off 12". Someone in my club pointed out that in my 90 I won't be as concerned with height loss as I will with depth loss so going full internal may not be that bad. Most of the guys here seem to be ending up with around a 5"x5" or so internal overflow right.. 5" is hard to give up at least for me mentally. |

Matt:
Is it poosible to do an external box on you new tank design? Who is building the tank? Even Perfecto now will ( if you beg Not pushing a brand here - I was just surprised that they are now trying to compete with some of the smaller, more custom builders. T

Bean, i seem to get a periodic siphon on my system as it flushs every so often. Am I getting air into the system somewhere???
