durso with a cage? Lots oh noise

[pr3dict]

Soooo I'm new to this game and I've been doing a lot of research and maybe I just have super sonic hearing but my aquarium is lllooud.

I have, what I think to be a durso standpipe.

This is exactly what mine looks like.

I think its from bubbles but I'm not sure It just sounds like a ton of running water and bubbles every once and while like a blurprlble.

also my tank is always dirty for some reason but thats another post...


Please help

Yes, that is a durso .... aqueon if I’m not mistaken. Is the air vent nipple at the top of the assembly clear? Durso can be noisy certainly - depends usually on how much flow you are running. Try backing off your pump and see if the noise is reduced.

Deff looks like an aqueon from that patent design haha... So Should I switch to a stockman or something? I have my pump at 40% which is like 300gph on a 60 gallon display

the quietest is a tuned bean animal. but they require 3 holes in the tank.
I have a modified one, essentially a bean animal without the emergency drain.
it's totally silent 99% of the time, and when it starts to make noise, it's a simple screen cleaning, or valve adjustment.

That seems complicated lol. Any other suggestions?

You can add an adjustable air valve to the top air hole. This will allow for a little adjustment of the air to water ratio. It might help.

Durso Standpipes

Durso Standpipes are used to make your aquarium overflow (weir) nearly silent. We help you make your own or purchase them ready made!

One of the reasons the durso gets noisey is because the air line on top gets clogged.
Keeping it clear and going bigger and adding a air valve can help alot.

@pr3dict, Describe the "noise" your hearing. Is it a "gurgling" sound or a "toilet" flush sound?

The durso curved elbow needs to be just below the waterline of the overflow box.

As @lapin and @mfinn have stated, the top of the drain should have a air hole. If it's clogged or if the air to water ratio is too little, a "toilet" flushing sound will happen as pressure builds up and releases.

 

[pr3dict]

It's a running water sound. Like when a toilet bowl is running... It's so much worse now that I drilled a hole bigger in the top. I just bought air line and an adjustable valve to try that... If this doesn't work I'm going to try the stockman type and if that doesn't work then I guess I'll do the her ie though I really don't want to do that because then I need to basically redo my entire plumbing.

Maybe needed. Splitting the drain into two at the sump may be causing this. Best to have it drain as a single drain into the sump.

Interesting. Veryyyy interesting. Again I'd have to redo my plumbing. The sump I have has 2 sealed channels that the pipes go into. They are about 6 inches below the water line. Maybe if I drill holes in them it will help instead of having it go down as it does now? I just don't know. #physics.

 

[Flippers4pups]

Water is hitting the 90's and with the drains exiting underwater, may be causing some back pressure. Water builds up in the pipes with air trapped because of the 90's. This then flushes when there is enough water above to push the water out.

You could try cutting the ends of the drains above the water line in the sump first.

Howdy

Not sure if I missed it, what tank do you have, as far as drilled, number of holes. As said, the 90 isn’t adding much to the party. Usually one is plumbed for siphon and one for an emergency drain in a herbie overflow. ( I think, not 100% on that. I have mine that way.)

Lampin attached a good link. Here’s a basic read also

65 gallon oceanic.

I would guess it’s drilled running the durso. How many holes does it have?

Two bulkheads. 1 for the durso and 1 for the return.

Ah, check out lampins link and google tuning durso. There are ways to reduce noise.

Slowing return pump helps but you loose flow. Another option is set up the 2 holes as a herbie and run the return line up and over.

Maybe someone running that set up can give some first hand experience running it that way.

 

[link81]

if you end up needing to re-pipe, can very easily use an over the back return, and use the 2 holes in the overflow for the drain. The smaller one can get a valve, and be the full syphon line, and the larger gets no valve, and is the overflow/emergency line.
adjust the valve so there is just a small trickle down the overflow line.
Each line uses a separate bulkhead in your sump.
