Thanks everyone for your responses. You all said what I wanted to hear... It's loud. I have two pumps, first is a little giant 3 and it pumps about 13 feet up. It's undersized, but running flawlessly for 5+ Years, and is really quiet. I'd like to have a bit more power but that's not the issue. Issue is the second pump, a panworld that is just as powerful as the little giant but is noisy and since it pumps the Etss skimmer and a few reactors, I'm having to fiddle all the time with my skimmer adjustments. My thought was to get a reliable pump for the return, up 13 feet and to run GFO, and carbon reactors while having the little giant dedicated just for the skimmer. I keep reading about reef flows and leaks. Dolphin pumps may be the way, but iwaki is a time and true pump.... But guess the nose is a factor I need to assess how important that is...
