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.
