Years ago i read that article and I used the your return setup with great success on a 75 gal. however I have read many different variations to your design coupled with either a weir or coast to coast drain. there were pros and cons of each but I don't remember... In a month or so I will be turning my attention to plumbing my 300 and I want to be as current with the information as possible without combing through tons and tons of posts.
It makes sense that it's under construction, because I went to your website last night and noticed there were a lot of supporting pictures missing....

Upsizing the Bean Animal Pipes from the bulkhead size
Does anyone know if it's worth upsizing the drain pipes after a 1" bulkhead to 1 1/4 and likewise in the overflow box on all 3 lines? I know the Durso utilizes the upsizing for the open channel pipe. Obviously it would be easier to not upsize because of all of the reducer bushings/adapters required to change the size. Also is a gate valve really useful on the siphon line or is a ball valve adequate? [IMG][/IMG]
Thanks! |

There really isn’t a need to increase the pipe size beyond that of the bulkhead. Much easier to stay consistent. I am actually replacing a durso with a bean and have a 1-1/4 bulkhead that i am reducing to 1”
Ball valves should only be used for on/off. It would be very difficult to balance the flow without a gate valves adjustability Sent from my iPhone using Tapatalk |

Upsizing the pipe is a good idea at times but it definitely isn’t a rule eighther. I definitely wouldn’t downsize the pipe. Need to know more about your system to say if it would be worth it or not. The biggest thing u gain by upsizing the pipe is the open channel can handle more flow & remain silent. It would also be able to handle more flunctuation in the system & remain silent without having to tune the valve.
So it isn’t as much about overall flow in most cases. A 1” syphon can handle the majority of people’s systems. The larger the open channel the more water it can take & remain silent. For example, say u run a reactor or manifold off your return pump. If u have a 1” plumbing & u turn the reactor off, u will more then likely have to adjust the valve for it to remain silent. If u have 1.5” plumbing u could turn off the reactor or whatever it’s feeding & the system remain quiet because the 1.5” open channel can handle the flunctuation. A gate valve makes it easier to fine tune the system but I wouldn’t say they are a must. I have had no issues using ball valves in the past & I still use a ball valve on one of my setups. I like to have as long of a overflow box as possible, so a ball valve works fine. The newer ghost type overflows that have become popular can have more issues using a ball valve because the exterior boxes are small. It’s really just the 12” & maybe 16” boxes because they hold so little water. Once u get to the larger versions it shouldn’t be a issue. Not all ball valves are created equal. The really cheap ones would have more issues then a higher quality double Union ball valve for instance. Last edited by Lsufan; 04/08/2018 at 11:12 PM. |

I think gate valves are a waste of money... I have never had an issue dialing the system in with a ball valve. That said, in 10 years I can count on one hand the number of times I have had to adjust the system.

a 48" notched weir with 1/4" wide notches that are 1/2" apart (1/4" teeth) would have about 93 notches, at a depth of 1" per notch that should flow over 3500 GPH so I would sa you're fine, from a flow perspective. Make the notches 1.25" deep and you're over 5000 GPH, if you then factor in the teeth clogging over time, even 50% clogging and you're well over 1500 GPH.
For comparison, the same weir at 48" with no notches only needs 0.25" of water over the top of it to achieve 1500 GPH.

OK, so here's the plan (tentatively)
I'm going to build a 48x36x24 tank with an external coast to coast overflow. I'm thinking it might be more structurally sound to extend the side panels (36" panels) an extra 5-6" and make the back panel shorter than the front. Then I would attach the back and bottom of the over flow to the side pieces creating a true coast to coast overflow. I plan on using your 3 pipe silent standpipe setup. I will drill an additional hole in the overflow bottom to run my return line, and may potentially include 4 holes in the back panel for a closed loop. My main question is, how much shorter should I make the back panel if I want it to be able to handle 1500-2000 gph silently? Also, is there a benefit of extending the side panels to help create the overflow box? My thought process is that the overflow box would be more than just siliconed to the back, therefore it would be less likely to leak/fall off

Depends on many factors I suppose. There's many ways to do it. But pics and/or a sketch help. I can't envision what you're describing, either that, or brain is in the wrong gear

Quick and dirty. This is a side view of the tank. Will the larger side panels make the external overflow stronger? (Less likely to come loose and leak)
Just a thought I had, wondering if it will work Sent from my SM-G930V using Tapatalk

I would just make the overflow box separate from the tank & attach it to the back of the tank. On a box that size I would support it with some triangle pieces under the overflow box.
As far as the notch in the back glass, it depends where u want the water level. I would be comfortable with it being 1.5”. Any more then that & the water level would look low inside of the tank. Any less then that & u start cutting it pretty close once u get wavemakers going on inside of the tank. How are u wanting to attach the teeth. On a box that size teeth won’t cause issues as far as flow. What it does is cut the surface skimming pretty much in half. I think teeth would be more hassle then it’s worth, which to me they aren’t worth much anyways because I prefer a smooth weir Last edited by Lsufan; 04/10/2018 at 08:23 PM. |

What confused me was the description of "extending the sides". I now caught that you are building the tank (or having it custom built). Out of glass or acrylic?

I'm an acrylic guy so I can't answer that heh heh
What I can say is that if you build with the sides on top, that's opposite of the normal technique (for both acrylic and glass) where the front and back panels are on top of the end panels (the edges of the ends are bonded to the inside face of the front/back panel) so "extending the sides" becomes a constructability change, and you may not want to go there. If anything, on the front of your tank, you're going to see the end of the side panels, which is kinda ugly. My personal advice would be to drill the back panel for pass-through holes and then use a very thin inside coast-to-coast and an outside box made of either glass or acrylic, and make those separate pieces. Basically either buy or make your own version of a Shadow or Ghost. The reason I say this is because it allows for a lot of flexibility and allow you to correct something if you later realize that it doesn't work exactly the way you want it or envisioned it, or if you want to do something a bit different, etc. Making is part of the structure of the tank sounds great on paper but it also locks you into a solution and limits your ability to change. Making a sturdy acrylic box and using bulkheads to hold it in place is a solid long-term solution. If you want some peace of mind, you can add in some kind of support method to take stress off the box and mitigate against any potential failure points (like weight of hanging off the back panel, if you're worried about that) Cutting a notch in the top of the back panel or cutting teeth in the glass creates a huge amount of failure points. Lowering the height of the back panel relative to the sides would probably work, then add in a notched attachment or gutter guard etc, there's more than one way to do it, but I go back to the idea of building an overflow solution into the tank as having it's drawbacks...because I've done it.

Im the one that called it a notch & probably shouldn’t have. It sounds to me he is planning on just making the back pane of glass shorter then the front & sides.
I’m no builder & they have calculators for glass thickness if u know how to use them. Imo 3/16 would be way undersized. The only way I see 1/4” being ok is if u use trim & have a center brace & it’s still probably to small. If u plan on it being rimless then I would think it would have to be atleast 1/2”. I don’t think 3/8” would even be enough. I’m not positive on that so u definitely want to find out before getting glass. |

Dumb question but when I hold my finger over the RO/DI line (connected to quick connect fitting) I don’t get a quick flush from the open channel. Any idea what may cause this? I have my siphon channel lower than the open channel. Can’t post a good pic because overflow is against wall.

Because it still has to purge the air from the pipe. So it would have to build up enough to purge the air. In order to test it out u would need to close the valve on the syphon like it got clogged. That way the water builds up in the overflow box enough to purge the air from the open channel

Ah that makes sense. Thought I had something wrong but was confused because it was running so quiet. Thank you for clarifying!

quick question here related to stopping/starting the return pump. Seems I have trouble getting the siphon going. When it's recommended to have the drain into the sump no deeper than 1/2" below the water level, is that when the system is running or when the return pump is off and the return line has siphoned down a bunch of water back into the sump?
