But: much too loud. It lies on the storage engine. All rigid, vibration transmitted as the sounding board of a musical instrument. Opinions, after the after about 14 days to put operation, unfortunately I can not share. Have the pump housings filed in the recording, a grommet used which supports the pump casing and yet fixed rubber between the removable floor. Now the pump impeller is mounted tightly and yet subdued, and the vibrations are not transmitted. She hums just barely audible, as I'm used to it by Eheimfiltern.
Clear plus: Power Consumption 3W, High filtering efficiency, long service life
Note: The conversion should make only experienced hobbyists, guarantee omission at this price not an issue.
