Silent and Failsafe Overflow System

[Mr.Tan]

Fired up my build for the first time tonight using fresh water only to check for leaks and do the tuning on it. It is a 29g tank with a 10g sump running a sicce syncra return pump and using 3/4" piping. The full siphon seems to be working perfectly and didnt take long to tune at all. But i think i might have tuned it wrong? I dunno... I did NOT install the tube yet on the open channel, i need to do that tomorrow. But i am getting a bit of water dripping/running noise coming from the OC as it drains into the sump. The FS and OC lines each drain 1" below the water line. What can I do to remove the noise of the water? or is it something normal i'll have to deal with? it really doesnt bother me but i just thought it was supposed to be quiet....?


also, i am going to install plastic ratchet clamps on the three drain lines (will remove the steel hose clamp) as well as the output of the return pump to keep the hose on

here is a video that shows the noise i mean

@ Mr. Tan - I'm going to suggest the same as above.

Open the FS valve a bit to reduce the noise/flow in the OC.

i think that solved the problem... or not? The OC no longer seems to be draining as much water. Now it has barely a trickle coming out, sometimes it looks like none and then barely anything comes running out of it. Is this normal? The only audible sound i get is the water running into my overflow now (which doesnt bother me too much) and my pump running (which isn't as quiet as i thought it would be :sicce syncra 2.0: )

there is a happy equilibrium between how much water the FS and OC siphon out. on mine it is the point where the water in the overflow is high enough to cancel out most of the noise, yet where the OC doesn't have a bunch of bubbles.

perhaps you need to close the FS just slightly until you get to that point?

I have another question. Can I attach a Felt Filter Sock with Draw String directly on the Full siphon standpipe end in my sump? If my power goes out and comes back on, will the sock affect my siphon break-in?

if the top of the sock is below the end of the siphon pipe then you would be fine. the problem I see with having it to where the pipe goes into the sock, is that as the sock gunks up the water level in the sock will go up and you will likely get back pressure if/when the water level in the sock goes well above the end of the pipe.

Can anyone help me out?

Reducing to 1" at the sump from 1.5" will not be a good idea. Although 1" at the top of the drain increasing to 1.5" will reduce the friction losses in the system, and yield a higher net flow, reducing at the bottom to 1" will kill the flow, and likely cause other "jet stream" effects you may not care for. Bypass the bulkhead inlets to the sump, and run the drains directly into the skimmer section of the sump.

Bad idea, for reasons already stated.

OK so I installed a mesh filter bag on the Siphon standpipe since a felt one would be a bad option. I unplugged power and tested the siphon with the sock on and siphon started normally at around the same time it takes without a sock on. I know I gotta change these after 3 days but I will try again when the sock gets more cloggued...and post my results.

The issue of the water rising is the same if it's mesh or felt. Also, a full siphon + filter sock is not good for any fish that may get sucked down it. I've never had a fish take a ride down the siphon yet but many others have.

If the sock clogs enough, it won't easily release air on startup. So the system might never purge, and then if it does, flow will be reduced forcing the OC to run stronger and probably oscillate. While this would be an audible indication that your filter sock needs cleaning, it also hampers your system failsafe operation, which is the point of the BeanAnimal system. I would just not do it.

Any other alternatives of hanging the sock somewhere else then? I don't have a specific hanging section for socks in my sump and that was the only possible place i could fix them on. I don't have any fish/inverts/corals yet in my whole system. I'm at my 5th week of cycling tank. I had a diatom bloom and I see it slowly diminish but alot of crap is going through my skimmer and i wanna diminish this with socks. I know skimmers are not suppose to pick up debris but mine does. The smell is horrible too...

Why do you even want to run socks?

I have read to many parts of this thread , but it´s impossible to read all of it , and i have one question ... I hope someone could help me !!
Why in the Beananimal project both standpipe ( full siphon and open channel ) are at the same level and all videos that i saw on Youtube the open channel standpipe is always a little bit higher then the full siphon ? and the emergency standpipe always a little bit lower then the open channel standpipe ? in fact the emergency standpipe is always in the middle level betwen open channel and full siphon on all youtube videos ... what is the correct setup to do ?

We're here just not in a conversational mood!

Just because it's on the internet (or YouTube), doesn't make it true!

You want the full siphon to start first. On most systems this inlet is pointed down. The OC can be equal to or slightly higher. It takes some small flow once the FS is fully running. The emergency can be higher but not so high as to flood the house!

They can all be at the same height and modified with the final fitting.

It's discussed every few pages.

Here's how I have mine setup and discussing heights with someone else. And pictures shown in following posts.

I'd like to setup my leemar 90 with a BA if possible but I've got 2x 3/4" and 1x 1-1/4" holes in my overflow.

Can I do a BA with this?

3/4" for siphon and open channel and the big one for the emergency?

 

[rpaschoal]

So thanks so much ...
My tank is a 120 g and i am planning an external oveflow box with 2 x 1,5 bulheads and 3 x1,5 to sump with two Boyu Eco 5.000 l/h pumps ... is it correct ?

I'm assuming those are bulkhead sizes, not hole sizes.

3"4" is too small imo. I suppose it could be done, but I've never seen it done. 1" drains is as small as I would go.

If anything, the 1" drain for full siphon - but then the system is beginning to become unsafe.
