Marineland durso

[riche]

I picked up a tank yesterday ( first brand new tank ever) Ya well it is a corner overflow and comes with a durso pipe.

My question is has anyone used the one that comes with the tank, its a 1" bulkhead but the durso has been upsized to 1-/2". So its rather big, and it has the hole drilled in the top with a little tube.

Will this be quite or should I get the stuff to make it a herbie? Trying not to go that route as I dont want the returns hanging over the back

The Marineland provided durso has a distinct draining/running water sound. Setting up Herbie has its advantages for sure (safety, quiet, efficient).

I am using the standard durso provided with my 90g. Cannot for the life of me remember if its Marineland or Aqueon.... either way it works really well, but you can hear the water running 24/7. Doesn't bother me though.

The small hole in the top of the durso drain with the tube is for air to escape thus making the drain quieter. It's far from silent though.

Did the setup come with the return pipe & lockline?

I have the same brand setup. To greatly reduce the ‘running water ‘ sound I cut a 2-inch piece of plastic and used a zip tie to deflect the water to an area of the overflow where the sound is greatly reduced as a result.

Where did you put this 2" piece of plastic? I watched a video where a guy put a few zip ties in the pipe and let the water trickle down that way?

Yes it came with the return and locline.

What did you do to quiet the drain into the sump? I have my dc-6000 on the slowest speed and it still sounds like a waterfall in my sump, Ihave teh drain about 3 inchs into the water

Go herbie and run the return over the tank rim. I could never get the durso to be as quiet as I required, gave up and went herbie - perfect.

I'm going to go that route as I cant stand trying to "fix" this nonsense

I've got an acrylic sump with a PVC outlet on the inside that has slots along the bottom with a capped end and small hole in it. The drop to the mechanical filter tray is minimal thus there isn't much sound coming from the bottom. The sound I get is the water flowing over the overflow and down the flexible drain tube.

It's far from quiet by many folks standards.

Go HERBIE, it's ya birfday!

I'm going herbie for the win

 

[Greybeard]

I've owned many durso style systems over the years. In a family room, where the main activity is fish tank watching, fine. In a living room, where I'm trying to listen to conversation, or even the TV... Nope.

Durso... or BeAnAnimal (Durso + a safety) wins the noise category easily.

well since there is only 2 holes drilled in teh corner overflow Im going to go with the herbie, now is 1" pipe ok for both drains the tall one and the short one? Its a 65 gallon tank

+1

You'd think every manufacturer would be working on a modern "reef ready" tank that accommodates more than just a durso overflow by now.

1" bulkheads, right? Increasing the size of the pipe above the bulkhead will do virtually nothing to increase flow. 1" is fine.

A 1" pipe, full siphon, wide open, at gravity pressure should give you somewhere around 800 GPH. Size your return pump appropriately... on a 65g tank, say 650GPH, less head pressure... you're going to be fine with the 1" pipe.

now going with the herbie, will the drain be quite because of the valve? That';s my biggest concern, is I dont want the rushing sound of water going into the sump

 

[Greybeard]

Water flowing into water, with no air source, is virtually silent. The primary drain starts and ends below water level. If you can hear it, your ears are better than mine (not that big a challenge, really... I have tinnitus!)

All the valve is for is to slow the flow enough so that the primary drain is not quite sufficient to allow for all of the flow your return pump produces, so that water levels are maintained above the siphon tube inlet. You get a 'trickle' through the higher inlet drain, which doesn't make much, if any, noise.

Tuning a herbie is easy. Open the valve all the way, turn the pump on and let it settle to full flow. It'll be noisy... don't worry about it. Slowly close the valve until the water level starts rising, very slowly, in the overflow box. Let it rise, until it starts trickling down the 2nd inlet. Got too much going down the 2nd inlet? Open the valve a bit. This is why I recommend a gate valve. Ball valves just don't give you the control you need to regulate flow.

New systems may take some time to settle in... but once it's been running for a few days, you'll seldom have to touch it.

I do recommend using sandpaper to smooth, even bevel the 2nd (trickle) inlet opening. Seems to reduce noise a little.

A strainer of some sort over the primary (siphon) drain inlet is mandatory, in my opinion. An open tube, fully submerged, is far too attractive a target for snails and such.

Oh, and I always test for safety... while it's running normally, plug the primary drain. The trickle drain should be able to handle ALL of the flow, though it's going to be noisy. This is good... let's you know there's a problem. Another safety test is to plug BOTH drains. If your system is set up correctly, it will empty the return compartment, letting the pump run dry, BEFORE the tank overflows and makes a big mess. This is the reason for the BeAnAnimal setups... gives you an additional layer of protection to keep this from happening, but if you set it up right, it becomes unnecessary. Note: An ATO system can really cause you a headache on this one. It's going to detect low water, and try to refill it. The Tunze has a timer in it, where if the pump exceeds a given run time, it alarms, and turns the pump off. Nice feature

Two 1" is fine, just put a gate valve on the primary siphon, and extend the emergency / trickle to like 1/2 below the overflow weir lip, else it will waterfall down and make even more noise after about a 1" drop.

1/2" below?

 

[Kyl]

I have an Aqueon but I'll assume the Marineland is the same. The overflow front has the slits for the water to flow through, but it also has an internal channel that water will come up and over, circled red. Put the emergency / trickle drain line about 1/2" below the water line, sort of where the red line is.

This way you don't have the waterfall sound from the tank overflow into the drain chamber. It does mean that you will have that amount of water to account for in the sump when the pump is turned off and it drains down to the level of the primary siphon drain line.

 

[riche]

Well I ditched the durso and did a herbie and its silent. There is no noise what so ever

I have been taking pictures as I do all this work, so I can start a build thread

Silence is golden
