Hi, Are you stating that the pump will continuously be turn on for an hour or it will turn on intermittently within the hour for testing? I have google around there is a white unit and black unit. some are sharing the black unit is an older version? probably the white version has already address thi?Definitely not silent as you have the air bubbler. I wouldn’t define it as loud. I only have experience with an Alkatronic and the x10 and I’d say this isn’t any louder as the bubbler is about as loud as the dosing pumps themselves. The testing on the hour definitely makes it more noticeable tho.
