The video makes it sound way louder than it is in person, but it is still unacceptably loud. I am just setting all of this up on an 8ft 240g and I've never done a sump before so it's all new to me. I had a loud trickle in the overflows so I raised the durso height some and now it is a very minor trickle. The sumps were extremely loud with tons of bubbles so I raised the discharges from the bottom to just below the surface and added a T with an off-shoot standpipe to suck out all of the air. There's a cap on that with a hole in it because otherwise it sounds like a toilet echoing in an empty bathroom. All of these changes cut the sound down by 3-fourths to what is in the vid but it is still too loud. My pumps are Mag 18s and they hum too loudly, too (one more than the other) but they are both clean and undamaged and that's what I'm going to use for now. Any questions? I would love some suggestions so that I can get this thing up and running!
