I got my hands on 2 mp40 pumps to try out. First impression was the look of the pumps they are very nice. I quickly looked through the manual 40 some pages. This pump has some nice running modes. I got them running I could hear them especially when I turned them up, they are really noisy in pulse mode. I can't run them at max speed anyways because it disturbs my sand. I turned them down and they are not so loud but definitely noticeable. I'm currently using reef crest mode.
