Basically on the open channel the water has to get to the point where the two 90ís join together to make the U for it to drain any water. Basically where u have the dotted line drawn. The water would have to get over that point before the open channel takes any water being it isnít a syphon.

Is the open channel taking any water when the water level is flunctuation in the overflow box or is it never getting to that point?

If the water in the overflow keeps fluncuating to where it raises & then all of a sudden completely drains the overflow box, then eighther the syphon is kicking in & out of syphon or the open channel syphons & empties the overflow before the syphon kicks in on the syphon drain. That is one of the reasons the output of the airline is supposed to be above the emergency drain.

It sounds like u are just having trouble getting the syphon tuned in, so when the syphon kicks in it just empties the overflow box until the syphon sucks air. When the syphon sucks air the water will build up again until the syphon purges the air again & when it does it just empties the overflow again.

When u get the system going the first thing u want to try & achieve is to get the water in the overflow box stable to where it doesnít flunctuate. Once u get to that point is when u can fine tune it to get the water level to where u want it. In your case u are going to want the water level right where u have the dotted line drawn on the open channel.

I would start with the valve fully open. Let the system get going & close the valve half way & see what happens. If the water level still doesnít rise & isnít steady then u will need to close the valve even more. Depending on flow & size of the plumbing u may end up having to run it with the valve halfway to 3/4ís of the way closed.
Okay, i'll give it another shot with more time at each setting.

To answer ? If water ever reaches the U.... If I do reset via open full siphon such that box drains below open inlet and start over here's what happens. Dial gate valve partially closed until water begins to rise, maybe 80%open. Water rises to U. Once it hits the U it immediately drains it down to the open inlet and from there on begins surging up and down never reaching the U again. That's why I thought a vacuum had occurred.

To add to this I ran another crude test to try and confirm some thoughts. I have my airline in a cap similar to Beans original design. So I just took the entire cap off with the airline tube to allow more air, again thinking a vacuum was occurring. Thing is this did help, albeit not solved nor quiet. So at the time I was still thinking it was a vacuum issue. But sounds like you don't think the vertical is effecting it, so I'll play with it more because I'd prefer not to cut it out.

Solved! Was just needing a little time for regulating with the setting / dial in issue. As with most things in the hobby, patience is key! Thank so much for the help!

Yea, somtimes it takes some playing with it to tune it in. Especially with a gate valve because if u are way off & only making small adjustments it seems like u are getting nowhere. It sounds like water level in the overflow would build up to the U on the open channel before the syphon could purge the air for the syphon to kick in. When the syphon would kick in it would drain the overflow because the valve needed to be closed more.

I was surprised by how closed it was. I suppose it makes sense now considering its 1.5in pipe serving a 75g. Meaning tuned with my return pump its 84% closed (21 of the available 25 qtr turns on my gate). I'm just glad its working and dead silent!

Hello, I’m picking up this tank tomorrow and wondered if there was a shot to do a modified bean animal with this. It’s a 72x24x36. I think the small standpipes are either 3/4” or maybe 1” at biggest. I appreciate your thoughts.

Here is how I am going to set up my Bean Animal system./

I just bought the Synergy 20'' external overflow box for my new 150 display that I am currently building. Here are few pixs! The only thing that I glued are the 1.5'' unions and then I will reduce down to 1'' for the bulkheads on my sump. For my returns I will be going 1'' and reduce down to 3/4'' locline. The last picture will be the way I hard plumb my system with Wye Check Valves
