Does anyone know where I could order 1" x 1.25" slip street elbows? I haven't seen them anywhere locally, and haven't been able to find them online.

I tried that, but my overflow is too tight to fit the larger elbow.
Bean, great stuff here and on your web site!!!! And from p-burg!!! Steeler Fan, good God man do you drink Iron City?
Ok little of topic but my real question is on your web site you built a base for your tank with some type of mdf or something, what I want to know about is the process of the clear arcylic self leveling sealer. what it is, where to get it......
thanks

Just wated to say tanks for the idea..
It's working great in my 55..
I didn't have room for the 3rd safety line but my testing shows that the my stockman side can handle full flow if necessary and in the event of a full blockage the pump chamber runs dry before a flood..
In the event of a full on flood (how that would happen i I don't know)
the top of the stockman is an open pipe (not enough flow through it to make any noise anyway) It's ends below the rim of the tank and would go full siphon when it's covered and bypass any in skimmer box blockage.
I'm only pushing about 400 gph, returns are 3/4"
Soup cans are only temporary

I am having a 60 X 24 X 24 built and up till today was going to use a herbie with overflow boxes. I now want to have an external coast to coast overflow with bean's set up. A few questions. I will be using a dart (4300 gph) that will feed the tank and a frag tank (probably herbie here)
1) How deep / wide should the external overflow be? Bulkheads in the bottom or side of the overflow box? (would prefer the bottom to keep width down)
2) Should I use 2" piping to ensure plenty of water for the dart to push or will 1.5 be sufficient?
3) How can I set up my sump so that my internal venturi skimmer will have a slow enough flow rate? Dedicate the siphon to the skimmer the other drain to another portion of the sump? (I want as much return flow as possible {sps dominated} yet still provide the skimmer with adequate contact time with passing water.
4) Any way to hide the return lines (rimless tank)? i.e. cut holes for the return or just pipe them over the top?
Thank you so much in advance for any help.

2 All-Glass Overflow boxes

beanAnimal,
I've read most of this and the old Herbie thread in search for a good overflow solution for my system. I have a 210 gal display, 75 gal sump, and 40gal fuge.
My display is an AGA with 2 built-in overflow boxes, each contains (1) 3/4" bulkhead & (1) 1" bulkhead. I just purchased a Reeflo BlackFin 3500 and expect it will be pushing between 1800gph and 2000gph after head pressure loss and tapping off the return to feed my fuge.
If I set up all 4 pipes (2 in each overflow box) as standard durso pipes, I fear I may not have enough buffer room to handle the amount of flow I want to push through my tank; hence the searching for and reading of this thread.
2 questions:
1. Can I accomplish your design given my current overflow boxes (I don't have 3 bulkheads per overflow)? If not do you have any recommendations for a modified version of your design?
2. The focus of this thread has been on “quieting the overflowâ€Â. This is nice, but my focus is drainage capacity. Do you think this method provides me the best drainage capacity for my setup, or would I be better off with 4 durso (regardless if it is louder or not).
Also, I drop my water into a filter sock, and the end of the pipe is above the water level in my sump. The filter sock dampens the noise and it is in a closet in an adjacent room anyways...
Thanks in advance for the help.

Hey Bean, I will be receiving today a new 260g.(84"x30"x25 h") and was planning on copying your design for the drains. I had planned to use the calfo-style overflow going across one of the 30" ends, but it recently dawned on me that the 3" euro-bracing would be a problem for the internal calfo overflow. Can you or someone who has had to deal with this type of situation suggest a way to incorporate this type of overflow without going external? The tank has not been drilled and has no overflows so I will be starting with a clean slate. Thanks.

Bean, First off awsome work. I saw you post and it got my wheels turning. I was thinking of doing a 75 like you. Do you think 2 set of the calfo overflows will work on a 75. I wanna try to set up a 75 without having to use power heads. I know a big pump is needed. My plan was to use 2 of the reeflo balck fin 6000. So each calfo would have approx. 4000 GPH. Any input or have I lost my mind.

mkarston just saw your post. I run a small pet store in eastern NC.(greenville) Good too see local folks.
I was thinking if you could drill the tank and add a calfo overflow in there and use the AGA overflos as returns. Just an idea.

Anyone think this is similar to Bean's design and should work as well?
From the owner of this image, here is how it works:
BEGIN QUOTE
Once things get flowing, you dial the gate valve back until the water begins to back up into the overflow box. At a magic point, the water level in the overflow box begins to generate enough head pressure to precisely match the amount of flow you are putting in. At that point, water flows silently into the sump because no air is drawn into the drains...No air, no sound, no bubbles, no splashing in the sump..silence.
END QUOTE
It seems to me this is very similar to Bean's design and might actually work better ?

Then they are not "dursos" they are just standpipes
Yes.. It can be at the same height, but raising it a 1/2" or so may make your tuning a bit easier.
Yes, it will work the same.
Keeping the siphon deeper will keep the air out. The valve on the siphon standpipe adjusts the water level in the box also.

Most of my "stuff" has gone... I have a few hayward spa pumps somewhere (brothers shed I think). 56J wetends should be fairly easy to find though.

If setup properly, then yes they should be as silent. The siphon should make no noise. The open channel may make noise if you have a stream of water dropping straight down the middle of it though. There are plenty of creative ways to fix this....
canting the pipe to the side...
slide a bit of airline tubing into it....
etc...

Bottom. Size, enough to fit the standpipes and elbows and get your hand in to do work.
There are a lot of variables... but 2" would be fine.
Tough question... Some folks have teed off the siphon standpipe to feed the skimmer compartment.
Only you can decide that.. .over the top works fine... but drilling is cool too. The oceans motions devices are wonderful in either case.

Re: 2 All-Glass Overflow boxes
There is no easy way to setup my system between 2 boxes. You are pretty much stuck with the "herbie" setups in each box and no failsafe.
A single 1" siphon will easily outperform 2 dursos, if not 3 or 4 (depending on how they are adjusted, as a durso can be pushed noisily towards a full siphon.)

1/2" - 1" maybe... Anyting is better than nothing, but the setup can work with them at the same height (you just have to be aware that you can not submerge the pipe exits deep into the sump).
