Ian, Ya both pipes are submerged. My setup is one drain from Tank, into two sump lines. One at each end of the sump. Skimmer>pump<Refugeum Is my plan, but dont think I'll have enough room in 10g sump. Quite a bit of air comes down the Durso drain. I have small air holes drilled into the top of the Durso too, 6 .045" holes. Just enough to stop the water in the overflow from surging. Most my noise is from Durso gurgling too.
