Water Flow Noise

[bart84]

I am curious if anyone has this problem or knows anything about. During the day my tank is dead quiet until my lights go off. Then for some reason all you can hear if the water flowing between the DT and the sump. Any suggestions would be great.

What kinda overflow setup?

Are you running a sock on your output into the sump?

Sorry guys. 75 gallon with a 40 sump, bean drain, all 1" and no socks. Like I say it's dead quiet till the lights go out. Then you can hear the water trickling and flowing between the tank and sump.

 

[EricTMah]

That's really odd.

No kidding. I can figure out why it's doing it. I was kinda thinking maybe expansion and contraction with the heat ?

 

[saltyair]

How do you top up the sump? Do you change your fan/pump settings at night?

 

[jeffopentax]

Do your lights have a fan? If so, they could be masking the water sound til they go off. Try opening your full syphon ever so slightly.

slow your flow rate just a touch

Do your powerheads have a sensor and go into night mode?

Does the trickle have a down turned inlet with a vent like a durso or vent with a hose like the actual Bean design?

I will try that tonight

No sensor, they are koralia gen 3 and my trickle is just a straight riser with an open top.

Don't know why you only notice this after lights out.....but anytime it's running down a trickle with a straight open top it will make noise. Add a couple of elbows so it is turned down and drill a hole in the top to prevent siphon (make it work like a durso) then the trickle will be silent unless you start pushing major flow through it.

 

[bart84]

I will try that as well. I have a couple 90's in my stock pile. Thanks.

Yeah i know the fans on my light cover up my trickle sound if its started taking on to much water. Fot the most part the i just adjust my gate valve and all i can hear is my returns moving the water surface...that and the equipment.

 

[reef keeper]

The bean needs the down pipe 1" in the sump below the waterline. That's what makes it silent

 

[pulpfiction1]

im sure youve seen this diagram,the only time i hear anything is if my trickle has
to much water comming down it,i can see bubbles into my sump when this happens.
i dial the rate in so that its silent

11 years old, that's funny Dave, Funnier that it's quiet at night, maybe you just notice it more with lights out. Happy belated Buddy

I think its all your coral growing big and strong, or could be that bristle worm that wants out and is drilling a hole in seem of the bottom of the tank.


My money is on the fan masking the sound.
