The Open Channel (right) standpipe is open to the air via the airline attached to it. Because air is allowed in, the standpipe will not siphon or gurgle. The excess flow that is not being handled by the Siphon (middle) standpipe quetly flows through the Open Channel (right) standpipe. Because the flow is very low, very little air makes its way to the sump. Jordan: I believe your talking about how far down should you drill your holes. If thats the case, a general "rule of thumb" is 2x the size of the bulkhead hole. So for your 1.5" bulkheads, the holes should be 2 3/8" apart, and 2 3/8 down from the top edge of the glass, not the trim. Someone verify that?

The system works fine if the siphon and open channel wiers are at the same height, but if you can set the open channel standpipe higher than the siphon, you will help ensure that the siphon starts first. If you decide to drill holes in the standpipes, the only one that needs drilled is the siphon standpipe. Drill the holes just above the waterline of the sump (as observed during normal operation). |

hey beananimal - can i use this sort of pipe without issues? i have no idea if any of the various types of pipe are more or less inert relative to sea water. i will be running things like ozone on this large system. http://www.usplastic.com/catalog/ite...4369&catid=730

So I was looking into a Bean drain system for my 125 RR, and have a question. Since in theory, a full siphon can accomodate a huge amount of drain capacity, is this set-up a possibility.
I have a standard 125 6' Reef ready, with 2 overflows, 2 bulkheads per overflow. So I was thinking using one of the current return bulkheads for the full siphon, the currentdrain in the OTHER bulkhead as the regular dynamic drain, and the 2 other bulkheads as the emergency overflows. My tank is supplied with a Mag-18. CJ edit, my return lines would be plumbed behind the tank, and would peek over the tank and hang on the back, then would be terminated with the aimable locline returns. |

Hey Bean I have a quick question:
I've been using your overflow design for almost a year now and things have been going swimmingly. However, over the last two weeks I've noticed the open channel isn't working. When the water level rises to the height where the airline would normally start to take in water and start the siphon it doesn't do anything and therefore doesn't start to siphon. I've checked for blockages and there isn't anything in the air line or the open channel plumbing. I don't understand what could be going on. Any explanations?

I drilled the holes in the main siphon just as you explained right above the sump water line and I also raised the level of the open channel weir for kicks. Still, when I restart the system the open channel is draining significantly more water than how it runs when I tune the system to be quiet. Every time I restart I get a significant amount of noise. I can tune the system back to quiet each time as well, but that could get annoying...lol. Any ideas? Thanks for the help!

Lo and behold, it turned out to be the most obvious solution. I had accidentally turned a ball valve on the drain line which caused it to slow down and obviously the pump kept going at the same rate.....hence the sump kept filling up slowly but surely. If you have a ball valve or gate valve on that open channel you may want to check that. I know thats kind of a dumb obvious suggestion, but sometimes those are the ones that escape us the most in this hobby.

also, i just noticed that when I drilled the holes in the main channel siphon line, its causing a pretty loud gurgling noise in the sump area......Did I drill too big, too many????? I went 1/4" and about 5 holes.

It seems that drilling the holes worked and that raising the open channel weir by itself did not (I tried this first then drilled the holes). However, both solutions combined ensure that the main channel starts first. So that is working. Of course, with my luck, when one thing works something else doesn't.....what i said above about the holes in the main channel siphon line causing a very loud gurgling noise in the sump area is still true......the question then remains.....Did I drill too big, too many????? I went 1/4" and about 5 holes.

Newest issue......I removed the section of pipe that I drilled the holes into because of the noise they were making. I replaced with a shorter piece of pipe that is only about a half inch under the water line instead of 1.5"
When I did this the system restarted fine.....but after running for about 15 minutes or so, for no reason I can pinpoint, it kicked into hyper mode and the siphon began to work too fast to where it almost drained the overflow box and it began to suck in air. Almost as if I opened the gate valve more. When this happened I tuned it back down to allow for the overflow to fill back up. Once it did, it was perfectly silent and everything was great. And then I restarted again.......and sure enough, this time the Open channel took in more water than its supposed to and its gurgling. So in summary, when I drilled the holes in the siphon pipe just above the sump water level, everything started and restarted fine but the noise from that pipe was too much. Still, this is the only scenario where the system has restarted as its supposed to each time. Sorry to post so repeatedly in this thread but I really appreciate the help.

Please post photos of your setup or an explanation of your standpipes. Are they straight shots into the sump? What size are the pipes and fittings?
It sounds like you may have a small leak in your siphon standpipe causing it to be unstable. |

Hey Bean....thanks...here are some pics. I do have a tiny leak in my return line, but I have found nothing in in the main siphon channel.
The Drain pipes are 1.5" and same for any fittings used. As you can see from the pics, its not quite a straight shot, but we did try to minimize any use of 90 degree elbows. We used all 45's for all the drains. I did add the airline to the open channel after this shot: Where the pipes end up, a little less than 1.5" under the sump operating level.

Ok everyone I am need of some great thoughts on how I can make a dual Overflow when I cant drill the tank and only have about 2" or so behind the tank.
Shoot me some Ideas

Put an external overflow on the END instead of the back of the tank. And - are you talking about a BEanAnimal type overflow?

Not being able to modify the tank, would make it a bit difficult, no doubt. 2" behind the tank, will make just about everything else a bit difficult also. They make HOB overflows, but fitting in 2" I am not SURE about. Teesquare had the solution, hang it off the end. Redesign the canopy to make it happen.

And - suspend the lights rather than have the canopy sit on the tank.
Thewre are some advantages: 1. You can use a pulley system to lift, haold, and lower the suspended hood 2. By suspending the hood, the tank is easier to keep from overheating. T
