Marineland durso

[Forsaken77]

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

I had spoke to Richard Durso, who invented that drain, and he advised me that you could stick air line on the top of that little plastic pipe with an air valve and adjust the air once you get your desired flow rate going. Because I asked him if drilling the hole bigger would help. He said a bigger hole would suck more air. You want the perfect amount of air. You also want to try to avoid 90 degree bends. The air has to escape.

With a durso, if you try to push too much water it will be louder. The slower the flow, the quieter it gets.

Marineland uses a large diameter pipe, but reduces down to 1" at the bulkhead. So the whole drain isn't that big. Just the stand pipe.

This my setup Marineland 60 Cube Dead silent . Return running over the back. with the second pipe as emergency drain.
The return pipe is tight coming up from the sump into the tank so its not loose at all. I could force it out but the tank itself won't force it out of the tank plus with the glass lid on top is a extra safety even that isn't touching the glass.

The post above is a good idea and option. I can tell you from experience that the stock set up is very noisy. You not only get sound from the overflow but the splashing in the sump is unbearable. I eventually sold the tank and went with a Red Sea Max. It is dead silent. All you hear is the pumps running.

I don't hear anything but maybe the sound of the water returning to the tank.
