Hi folks. I just lit off my 20gal sump yesterday for testing. I am running a brand new Rio 20 HF that I purchased from Fish Tanks Direct. My question is, is this niose level normal for this pump? I have taken it out and removed the impeller. Everything looks good. No debris. and clean as a whistle. The impeller does seem to be a little off balance as I can feel vibration when I spin it. Is this normal for this pump? I think not, but I'm new to bigger aquariums.
