The 1.5" standpipe allows the open channel to flow more water quietly by allowing more air space and less change of gurgling or partial siphon. The larger the open channel diameter, the better. The larger diameter Siphon and Emergency drains help to increase their capacity by lowering resistance. |

Now, that is not to say that your setup will not work quietly. The water will collect on the bottoms of the standpipes at the level of the sumps surface. Sorry I don't have a better answer, but your setup is going to take some trial and error to get silent and a lot depends on your target flow rate. |

You are going to likely want to turn those valve handles around! They are going to be tough to manipulate in that position. You should also consider rigid support for ALL of the standpipes and CL pipes, as manipulating the valve can put tremendous torque on the bulkheads. |

I like the external overflow better from an easthetic standpoint and display standpoint. The eurobracing will get in the way of an "in tank" overlfow and make it hard to access. |

Glad to see someone with more holes in the back of the tank than mine has. Looks good!

My main return pump is about 1900gph @ 0' (but my tank is 10' above the pump and I will divert some flow to the refugium) so say around 1200gph from the overflow. If having two systems is not a good idea and being the anal retentive person that I am (I'm afraid of overflowing the tank and flooding my house) should I then use three of the six holes for your type of overflow and leave the other three as triple emergency overflows (each set at a slightly higher level)? Or possible as inlets for a CL (or would that starve my sump)? Thanks

You can use them as closed loop intakes, everything will balance. However, that means a significant increase in flow over the weir and a severe dilution of the surface skimmed water going to the sump. It also means certain cavitation when the return pumps are off (the closed loops will not get any water). In other words, it is not a good idea. |

Stupid question here. I understand how this works when using an overflow inside the tank, but how does an external overflow work and still go coast to coast and skim the waters surface? Would this be a box that hangs over the tank and is really just a giant siphon flowing into the external overflow box? The external would be so you don't have to drill holes in the tank or what?

Hey Bean,
Hope all is well. I just moved back to Pittsburgh, and was wondering how to get a hold of you? I noticed you no longer have the PM or Email option. I had some questions regarding a backup power system. Do you attend the PMAS meetings? If so... I'm not in any rush, and could talk to you at the next meeting. Thanks. (sorry for the hijack)

great thread. I learn something new about this hobby every month. amazing.
I created a thread about a year ago about helping to solve my micro bubble issue, and this is the answer. Reducing the air intake in the dursos. I can't believe the answer was right in front of me the whole time. Bean, I've dealt with you several times in the past, and admit, you like to be right and can be a real pain in the butt... but, you usually are right. Forgive me if this is already buried somewhere, but how can I retrofit my existing tank which can't be pulled out from the wall or drilled for extra holes? I have 4 dursos, 1.5" each, 2 in each compartment. I also have 2 more in a single compartment in the other room on a 75G. I'm wondering how I can retrofit this setup if possible? Even if it's only a version that helps reduce air intake? main tank, you can see the two overflows, each has 1.5" durso I think. refugium/angel fish tank in the dining room, has 2 dursos in this one, shared sump of course. Edit: I forgot to say, estimate 1000gph overflow rate in display, 400gph in fuge *Also, I have a wavemaker, and I assume the siphon tube would only be 1 of the 4 tubes in my setup? So will the waves that splash from one box to the other really screw up the consistency of operation of this device?

zactos, the wavemaker should not effect anything relating to the siphon tube. The "regular" durso drains will make up for any fluctuations in flow.
I have about 1000gph flowing through my "BeanAnimal" overflow setup and sometimes one of my Tunze streams creates a wave that adds a bit of "extra" water into the overflow box and the system handles it just fine. I have some pics of my setup that I need to post here.

If you have the room behind the tank. I would go this route as the internal box takes up a lot of real estate. If it is a decent sized box I would also use additional bracing in the form of gussets for the additional support. |

zachtos...
I am on the way out the door. I will attempt to answer your questions when I return this evening, or first thing in the morning. |

I haven't heard back yet for a design suggestion, but I have a few more questions to tack on. Must each pipe have it's OWN pipe leading to the sump? Or can they all be connected together before they proceed to the basement sump?
It is quite a chore to plumb them all seperately, I'm not sure how a shared pipe would affect the setup. I'm considering doing this setup in my display which has 4 x 2" standpipes, but only 1000gph turnover. I think I could use 3 of the four and let the fourth be capped off or unused? Does this sound right or is there another use for it? They are in seperate compartments so I think I would keep the overflow emergency pipes in one compartment, and the durso and siphon in the other? Or should I put the siphon and a emergency in one, and the durso and emergency in the other? There must be others consdiering this retrofit!

Bean, I am having trouble getting my overflows to restart normally. My system appears to be the same as your design. It runs great, but upon restarting it continues to cycle or purge itself until I open the siphon valve back to fully open. Then the system will regulate itself and I can close it back off some. Nothing else seams to work. I have three compartments in my sump and one drain line runs into each one. I cut the return PVC to about 1” above the normal water level and then went back and drilled some holes to help the air escape the returns. Am I missing something? What can I try?

In theory that means that 3 1" pipes can flow into a single 2" pipe and it would handle the flow.

The more I think about it, the more I think that maybe you shouldn't...hmmm. Not sure.
