New Guy & Durso Question

[412Reef]

Hi All!

First post! So happy to be apart of this community and hobby.

Got my first tank, sump, and everything this weekend went all out! It was predrilled and came with the plumbing kit for the return nozzle and drain. My question is on the Durso, when the tank is running how deep should it be? This is what it is currently like (tank running) and something tells me it maybe too submerged. The air hole is predrilled at the top and the water is not in or close to that. Thanks!

First off…


And didn’t know much about dorso drains. I setup my brothers tank that runs one. And only know it works haha.

plenty of people there that know about it that can answer your question.

In the meantime, here's the quick answer: water level should sit just below the top of the Durso, low enough that the air hole stays above water and open to air. If water is covering or close to that air hole, it's too high/over-submerged you'll get gurgling and lose the silencing effect. Adjust by tweaking your return/drain flow or the standpipe height until the air hole breathes freely with a steady, quiet vortex below it.

Welcome newer member!

I am going to suggest that you do not use a single 'Durso' styled drain, these can clog easily if a snail gets in there, which can cause a flood.

Better, is a two or three drain system that has an emergency drain to handle water if/when the main drain clogs.

Most predrilled tanks have a hole for a single Durso drain and a second hole for your return line. I'd use that return line hole as your emergency drain and then run your return over the rim of the tank, or drill a third hole for the return.

This article explains the difference between a single drain "durso", a two drain "Herbie", and a three drain "Bean Animal" style of overflows. Please know that these were all named for the people that developed them. Bean Animal is active here on R2R if you need help:
